Chapter 5. Cluster extensions

5.1. Managing cluster extensions

Important

Operator Lifecycle Manager (OLM) v1 is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

After a catalog has been added to your cluster, you have access to the versions, patches, and over-the-air updates of the extensions and Operators that are published to the catalog.

You can manage extensions declaratively from the CLI using custom resources (CRs).

Important

Currently, Operator Lifecycle Manager (OLM) v1 cannot authenticate private registries, such as the Red Hat-provided Operator catalogs. This is a known issue. As a result, the OLM v1 procedures that rely on having the Red Hat Operators catalog installed do not work. (OCPBUGS-36364)

5.1.1. Supported extensions

Currently, Operator Lifecycle Manager (OLM) v1 supports installing cluster extensions that meet all of the following criteria:

  • The extension must use the registry+v1 bundle format introduced in existing OLM.
  • The extension must support installation via the AllNamespaces install mode.
  • The extension must not use webhooks.

  • The extension must not declare dependencies by using any of the following file-based catalog properties:

    • olm.gvk.required
    • olm.package.required
    • olm.constraint

OLM v1 checks that the extension you want to install meets these constraints. If the extension that you want to install does not meet these constraints, an error message is printed in the cluster extension’s conditions.

Important

Operator Lifecycle Manager (OLM) v1 does not support the OperatorConditions API introduced in existing OLM.

If an extension relies on only the OperatorConditions API to manage updates, the extension might not install correctly. Most extensions that rely on this API fail at start time, but some might fail during reconciliation.

As a workaround, you can pin your extension to a specific version. When you want to update your extension, consult the extension’s documentation to find out when it is safe to pin the extension to a new version.

5.1.2. Finding Operators to install from a catalog

After you add a catalog to your cluster, you can query the catalog to find Operators and extensions to install. Before you can query catalogs, you must port forward the catalog server service.

Prerequisites

  • You have added a catalog to your cluster.
  • You have installed the jq CLI tool.

Procedure

  1. Port forward the catalog server service in the openshift-catalogd namespace by running the following command: 

    $ oc -n openshift-catalogd port-forward svc/catalogd-catalogserver 8080:443

  2. In a new terminal window or tab, download the catalog’s JSON file locally by running the following command: 

    $ curl -L -k https://localhost:8080/catalogs/<catalog_name>/all.json \
  -C - -o /<path>/<catalog_name>.json

    Example 5.1. Example command

    $ curl -L -k https://localhost:8080/catalogs/redhat-operators/all.json \
  -C - -o /home/username/catalogs/rhoc.json

  3. Run one of the following commands to return a list of Operators and extensions in a catalog.

    Important

    Currently, Operator Lifecycle Manager (OLM) v1 supports installing cluster extensions that meet all of the following criteria:

    • The extension must use the registry+v1 bundle format introduced in existing OLM.
    • The extension must support installation via the AllNamespaces install mode.
    • The extension must not use webhooks.

    • The extension must not declare dependencies by using any of the following file-based catalog properties:

      • olm.gvk.required
      • olm.package.required
      • olm.constraint

    OLM v1 checks that the extension you want to install meets these constraints. If the extension that you want to install does not meet these constraints, an error message is printed in the cluster extension’s conditions.

    • Get a list of all the Operators and extensions from the local catalog file by running the following command: 

      $ jq -s '.[] | select(.schema == "olm.package") | .name' \
  /<path>/<filename>.json

      Example 5.2. Example command

      $ jq -s '.[] | select(.schema == "olm.package") | .name' \
  /home/username/catalogs/rhoc.json

      Example 5.3. Example output

      NAME                                                        AGE
"3scale-operator"
"advanced-cluster-management"
"amq-broker-rhel8"
"amq-online"
"amq-streams"
"amq7-interconnect-operator"
"ansible-automation-platform-operator"
"ansible-cloud-addons-operator"
"apicast-operator"
"aws-efs-csi-driver-operator"
"aws-load-balancer-operator"
"bamoe-businessautomation-operator"
"bamoe-kogito-operator"
"bare-metal-event-relay"
"businessautomation-operator"
...

    • Get list of packages that support AllNamespaces install mode and do not use webhooks from the local catalog file by running the following command: 

      $ jq -c 'select(.schema == "olm.bundle") | \
  {"package":.package, "version":.properties[] | \
  select(.type == "olm.bundle.object").value.data | @base64d | fromjson | \
  select(.kind == "ClusterServiceVersion" and (.spec.installModes[] | \
  select(.type == "AllNamespaces" and .supported == true) != null) \
  and .spec.webhookdefinitions == null).spec.version}' \
  /<path>/<catalog_name>.json

      Example 5.4. Example output

      {"package":"3scale-operator","version":"0.10.0-mas"}
{"package":"3scale-operator","version":"0.10.5"}
{"package":"3scale-operator","version":"0.11.0-mas"}
{"package":"3scale-operator","version":"0.11.1-mas"}
{"package":"3scale-operator","version":"0.11.2-mas"}
{"package":"3scale-operator","version":"0.11.3-mas"}
{"package":"3scale-operator","version":"0.11.5-mas"}
{"package":"3scale-operator","version":"0.11.6-mas"}
{"package":"3scale-operator","version":"0.11.7-mas"}
{"package":"3scale-operator","version":"0.11.8-mas"}
{"package":"amq-broker-rhel8","version":"7.10.0-opr-1"}
{"package":"amq-broker-rhel8","version":"7.10.0-opr-2"}
{"package":"amq-broker-rhel8","version":"7.10.0-opr-3"}
{"package":"amq-broker-rhel8","version":"7.10.0-opr-4"}
{"package":"amq-broker-rhel8","version":"7.10.1-opr-1"}
{"package":"amq-broker-rhel8","version":"7.10.1-opr-2"}
{"package":"amq-broker-rhel8","version":"7.10.2-opr-1"}
{"package":"amq-broker-rhel8","version":"7.10.2-opr-2"}
...

  4. Inspect the contents of an Operator or extension’s metadata by running the following command: 

    $ jq -s '.[] | select( .schema == "olm.package") | \
  select( .name == "<package_name>")' /<path>/<catalog_name>.json

    Example 5.5. Example command

    $ jq -s '.[] | select( .schema == "olm.package") | \
  select( .name == "openshift-pipelines-operator-rh")' \
  /home/username/rhoc.json

    Example 5.6. Example output

    {
  "defaultChannel": "stable",
  "icon": {
    "base64data": "PHN2ZyB4bWxu..."
    "mediatype": "image/png"
  },
  "name": "openshift-pipelines-operator-rh",
  "schema": "olm.package"
}

5.1.2.1. Common catalog queries

You can query catalogs by using the jq CLI tool.

Table 5.1. Common package queries
QueryRequest

Available packages in a catalog 

$ jq -s '.[] | select( .schema == "olm.package") | \
  .name' <catalog_name>.json

$ jq -c 'select(.schema == "olm.bundle") | \
  {"package":.package, "version":.properties[] | \
  select(.type == "olm.bundle.object").value.data | \
  @base64d | fromjson | \
  select(.kind == "ClusterServiceVersion" and (.spec.installModes[] | \
  select(.type == "AllNamespaces" and .supported == true) != null) \
  and .spec.webhookdefinitions == null).spec.version}' \

$ jq -s '.[] | select( .schema == "olm.bundle" ) | \
  select ( .name == "<bundle_name>") | \
  select( .package == "<package_name>")' \
  <catalog_name>.json

5.1.3. Creating a service account to manage cluster extensions

Unlike existing Operator Lifecycle Manager (OLM), OLM v1 does not have permissions to install, update, and manage cluster extensions. Cluster administrators must create a service account and assign the role-based access controls (RBAC) required to install, update, and manage cluster extensions.

Important

There is a known issue in OLM v1. If you do not assign the correct role-based access controls (RBAC) to an extension’s service account, OLM v1 gets stuck and reconciliation stops.

Currently, OLM v1 does not have tools to help extension administrators find the correct RBAC for a service account.

Because OLM v1 is a Technology Preview feature and must not be used on production clusters, you can avoid this issue by using the more permissive RBAC included in the documentation.

This RBAC is intended for testing purposes only. Do not use it on production clusters.

Prerequisites

  • Access to an OpenShift Container Platform cluster using an account with cluster-admin permissions.

Procedure

  1. Create a service account, similar to the following example: 

    apiVersion: v1
kind: ServiceAccount
metadata:
  name: <extension>-installer
  namespace: <namespace>

    Example 5.7. Example extension-service-account.yaml file

    apiVersion: v1
kind: ServiceAccount
metadata:
  name: pipelines-installer
  namespace: pipelines

  2. Apply the service account by running the following command: 

    $ oc apply -f extension-service-account.yaml

  3. Create a cluster role and assign RBAC, similar to the following example:

    Warning

    The following cluster role does not follow the principle of least privilege. This cluster role is intended for testing purposes only. Do not use it on production clusters. 

    apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: <extension>-installer-clusterrole
rules:
- apiGroups: ["*"]
  resources: ["*"]
  verbs: ["*"]

    Example 5.8. Example pipelines-cluster-role.yaml file

    apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: pipelines-installer-clusterrole
rules:
- apiGroups: ["*"]
  resources: ["*"]
  verbs: ["*"]

  4. Add the cluster role to the cluster by running the following command: 

    $ oc apply -f pipelines-role.yaml

  5. Bind the permissions granted by the cluster role to the service account by creating a cluster role binding, similar to the following example: 

    apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: <extension>-installer-binding
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: <extension>-installer-clusterrole
subjects:
- kind: ServiceAccount
  name: <extension>-installer
  namespace: <namespace>

    Example 5.9. Example pipelines-cluster-role-binding.yaml file

    apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: pipelines-installer-binding
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: pipelines-installer-clusterrole
subjects:
- kind: ServiceAccount
  name: pipelines-installer
  namespace: pipelines

  6. Apply the cluster role binding by running the following command: 

    $ oc apply -f pipelines-cluster-role-binding.yaml

5.1.4. Installing a cluster extension from a catalog

You can install an extension from a catalog by creating a custom resource (CR) and applying it to the cluster. Operator Lifecycle Manager (OLM) v1 supports installing cluster extensions, including existing OLM Operators via the registry+v1 bundle format, that are scoped to the cluster. For more information, see Supported extensions.

Important

Currently, Operator Lifecycle Manager (OLM) v1 cannot authenticate private registries, such as the Red Hat-provided Operator catalogs. This is a known issue. As a result, the OLM v1 procedures that rely on having the Red Hat Operators catalog installed do not work. (OCPBUGS-36364)

Prerequisites

  • You have added a catalog to your cluster.
  • You have downloaded a local copy of the catalog file.
  • You have installed the jq CLI tool.
  • You have created a service account and assigned enough role-based access controls (RBAC) to install, update, and manage the extension you want to install. For more information, see Creating a service account.

Procedure

  1. Inspect a package for channel and version information from a local copy of your catalog file by completing the following steps:

    1. Get a list of channels from a selected package by running the following command: 

      $ jq -s '.[] | select( .schema == "olm.channel" ) | \
  select( .package == "<package_name>") | \
  .name' /<path>/<catalog_name>.json

      Example 5.10. Example command

      $ jq -s '.[] | select( .schema == "olm.channel" ) | \
  select( .package == "openshift-pipelines-operator-rh") | \
  .name' /home/username/rhoc.json

      Example 5.11. Example output

      "latest"
"pipelines-1.11"
"pipelines-1.12"
"pipelines-1.13"
"pipelines-1.14"

    2. Get a list of the versions published in a channel by running the following command: 

      $ jq -s '.[] | select( .package == "<package_name>" ) | \
  select( .schema == "olm.channel" ) | \
  select( .name == "<channel_name>" ) | .entries | \
  .[] | .name' /<path>/<catalog_name>.json

      Example 5.12. Example command

      $ jq -s '.[] | select( .package == "openshift-pipelines-operator-rh" ) | \
select( .schema == "olm.channel" ) | select( .name == "latest" ) | \
.entries | .[] | .name' /home/username/rhoc.json

      Example 5.13. Example output

      "openshift-pipelines-operator-rh.v1.12.0"
"openshift-pipelines-operator-rh.v1.12.1"
"openshift-pipelines-operator-rh.v1.12.2"
"openshift-pipelines-operator-rh.v1.13.0"
"openshift-pipelines-operator-rh.v1.13.1"
"openshift-pipelines-operator-rh.v1.11.1"
"openshift-pipelines-operator-rh.v1.12.0"
"openshift-pipelines-operator-rh.v1.12.1"
"openshift-pipelines-operator-rh.v1.12.2"
"openshift-pipelines-operator-rh.v1.13.0"
"openshift-pipelines-operator-rh.v1.14.1"
"openshift-pipelines-operator-rh.v1.14.2"
"openshift-pipelines-operator-rh.v1.14.3"
"openshift-pipelines-operator-rh.v1.14.4"

  2. If you want to install your extension into a new namespace, run the following command: 

    $ oc adm new-project <new_namespace>

  3. Create a CR, similar to the following example:

    Example pipelines-operator.yaml CR

    apiVersion: olm.operatorframework.io/v1alpha1
kind: ClusterExtension
metadata:
  name: pipelines-operator
spec:
  packageName: openshift-pipelines-operator-rh
  installNamespace: <namespace>
  serviceAccount:
    name: <service_account>
  channel: <channel>
  version: "<version>"

    where:

    <namespace>
    Specifies the namespace where you want the bundle installed, such as pipelines or my-extension. Extensions are still cluster-scoped and might contain resources that are installed in different namespaces.
    <service_account>
    Specifies the name of the service account you created to install, update, and manage your extension.
    <channel>
    Optional: Specifies the channel, such as pipelines-1.11 or latest, for the package you want to install or update.
    <version>

    Optional: Specifies the version or version range, such as 1.11.1, 1.12.x, or >=1.12.1, of the package you want to install or update. For more information, see "Example custom resources (CRs) that specify a target version" and "Support for version ranges".

    Important

    If you try to install an Operator or extension that does not have unique name, the installation might fail or lead to an unpredictable result. This occurs for the following reasons:

    • If mulitple catalogs are installed on a cluster, Operator Lifecycle Manager (OLM) v1 does not include a mechanism to specify a catalog when you install an Operator or extension.
    • OLM v1 requires that all of the Operators and extensions that are available to install on a cluster use a unique name for their bundles and packages.

  4. Apply the CR to the cluster by running the following command: 

    $ oc apply -f pipeline-operator.yaml

    Example output

    clusterextension.olm.operatorframework.io/pipelines-operator created

Verification

  1. View the Operator or extension’s CR in the YAML format by running the following command: 

    $ oc get clusterextension pipelines-operator -o yaml

    Example 5.14. Example output

    apiVersion: v1

5.1.5. Updating a cluster extension

You can update your cluster extension or Operator by manually editing the custom resource (CR) and applying the changes.

Prerequisites

  • You have a catalog installed.
  • You have downloaded a local copy of the catalog file.
  • You have an Operator or extension installed.
  • You have installed the jq CLI tool.

Procedure

  1. Inspect a package for channel and version information from a local copy of your catalog file by completing the following steps:

    1. Get a list of channels from a selected package by running the following command: 

      $ jq -s '.[] | select( .schema == "olm.channel" ) | \
  select( .package == "<package_name>") | \
  .name' /<path>/<catalog_name>.json

      Example 5.15. Example command

      $ jq -s '.[] | select( .schema == "olm.channel" ) | \
  select( .package == "openshift-pipelines-operator-rh") | \
  .name' /home/username/rhoc.json

      Example 5.16. Example output

      "latest"
"pipelines-1.11"
"pipelines-1.12"
"pipelines-1.13"
"pipelines-1.14"

    2. Get a list of the versions published in a channel by running the following command: 

      $ jq -s '.[] | select( .package == "<package_name>" ) | \
  select( .schema == "olm.channel" ) | \
  select( .name == "<channel_name>" ) | .entries | \
  .[] | .name' /<path>/<catalog_name>.json

      Example 5.17. Example command

      $ jq -s '.[] | select( .package == "openshift-pipelines-operator-rh" ) | \
select( .schema == "olm.channel" ) | select( .name == "latest" ) | \
.entries | .[] | .name' /home/username/rhoc.json

      Example 5.18. Example output

      "openshift-pipelines-operator-rh.v1.11.1"
"openshift-pipelines-operator-rh.v1.12.0"

  3. Edit your CR by using one of the following methods:

    • If you want to pin your Operator or extension to specific version, such as 1.12.1, edit your CR similar to the following example:

      Example pipelines-operator.yaml CR

      apiVersion: olm.operatorframework.io/v1alpha1
kind: ClusterExtension
metadata:
  name: pipelines-operator
spec:
  packageName: openshift-pipelines-operator-rh
  installNamespace: <namespace>
  version: "1.12.1" 1

      1
      Update the version from 1.11.1 to 1.12.1

    • If you want to define a range of acceptable update versions, edit your CR similar to the following example:

      Example CR with a version range specified

      apiVersion: olm.operatorframework.io/v1alpha1
kind: ClusterExtension
metadata:
  name: pipelines-operator
spec:
  packageName: openshift-pipelines-operator-rh
  installNamespace: <namespace>
  version: ">1.11.1, <1.13" 1

      1
      Specifies that the desired version range is greater than version 1.11.1 and less than 1.13. For more information, see "Support for version ranges" and "Version comparison strings".

    • If you want to update to the latest version that can be resolved from a channel, edit your CR similar to the following example:

      Example CR with a specified channel

      apiVersion: olm.operatorframework.io/v1alpha1
kind: ClusterExtension
metadata:
  name: pipelines-operator
spec:
  packageName: openshift-pipelines-operator-rh
  installNamespace: <namespace>
  channel: pipelines-1.13 1

      1
      Installs the latest release that can be resolved from the specified channel. Updates to the channel are automatically installed.

    • If you want to specify a channel and version or version range, edit your CR similar to the following example:

      Example CR with a specified channel and version range

      apiVersion: olm.operatorframework.io/v1alpha1
kind: ClusterExtension
metadata:
  name: pipelines-operator
spec:
  packageName: openshift-pipelines-operator-rh
  installNamespace: <namespace>
  channel: latest
  version: "<1.13"

      For more information, see "Example custom resources (CRs) that specify a target version".

  4. Apply the update to the cluster by running the following command: 

    $ oc apply -f pipelines-operator.yaml

    Example output

    clusterextension.olm.operatorframework.io/pipelines-operator configured

    Tip

    You can patch and apply the changes to your CR from the CLI by running the following command: 

    $ oc patch clusterextension/pipelines-operator -p \
  '{"spec":{"version":"<1.13"}}' \
  --type=merge

    Example output

    clusterextension.olm.operatorframework.io/pipelines-operator patched

Verification

  • Verify that the channel and version updates have been applied by running the following command: 

    $ oc get clusterextension pipelines-operator -o yaml

Troubleshooting

  • If you specify a target version or channel that is deprecated or does not exist, you can run the following command to check the status of your extension: 

    $ oc get clusterextension <operator_name> -o yaml

Additional resources

5.1.6. Deleting an Operator

You can delete an Operator and its custom resource definitions (CRDs) by deleting the ClusterExtension custom resource (CR).

Prerequisites

  • You have a catalog installed.
  • You have an Operator installed.

Procedure

  • Delete an Operator and its CRDs by running the following command: 

    $ oc delete clusterextension <operator_name>

    Example output

    clusterextension.olm.operatorframework.io "<operator_name>" deleted

Verification

  • Run the following commands to verify that your Operator and its resources were deleted:

    • Verify the Operator is deleted by running the following command: 

      $ oc get clusterextensions

      Example output

      No resources found

    • Verify that the Operator’s system namespace is deleted by running the following command: 

      $ oc get ns <operator_name>-system

      Example output

      Error from server (NotFound): namespaces "<operator_name>-system" not found

5.2. Upgrade edges

Important

Operator Lifecycle Manager (OLM) v1 is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

When determining upgrade edges, also known as upgrade paths or upgrade constraints, for an installed cluster extension, Operator Lifecycle Manager (OLM) v1 supports existing OLM semantics starting in OpenShift Container Platform 4.16. This support follows the behavior from existing OLM, including replaces, skips, and skipRange directives, with a few noted differences.

By supporting existing OLM semantics, OLM v1 now honors the upgrade graph from catalogs accurately.

Important

Currently, Operator Lifecycle Manager (OLM) v1 cannot authenticate private registries, such as the Red Hat-provided Operator catalogs. This is a known issue. As a result, the OLM v1 procedures that rely on having the Red Hat Operators catalog installed do not work. (OCPBUGS-36364)

Differences from original existing OLM implementation

  • If there are multiple possible successors, OLM v1 behavior differs in the following ways:

    • In existing OLM, the successor closest to the channel head is chosen.
    • In OLM v1, the successor with the highest semantic version (semver) is chosen.

  • Consider the following set of file-based catalog (FBC) channel entries: 

    # ...
- name: example.v3.0.0
  skips: ["example.v2.0.0"]
- name: example.v2.0.0
  skipRange: >=1.0.0 <2.0.0

    If 1.0.0 is installed, OLM v1 behavior differs in the following ways:

    • Existing OLM will not detect an upgrade edge to v2.0.0 because v2.0.0 is skipped and not on the replaces chain.
    • OLM v1 will detect the upgrade edge because OLM v1 does not have a concept of a replaces chain. OLM v1 finds all entries that have a replace, skip, or skipRange value that covers the currently installed version.

Additional resources

5.2.1. Support for version ranges

In Operator Lifecycle Manager (OLM) v1, you can specify a version range by using a comparison string in an Operator or extension’s custom resource (CR). If you specify a version range in the CR, OLM v1 installs or updates to the latest version of the Operator that can be resolved within the version range.

Resolved version workflow

  • The resolved version is the latest version of the Operator that satisfies the constraints of the Operator and the environment.
  • An Operator update within the specified range is automatically installed if it is resolved successfully.
  • An update is not installed if it is outside of the specified range or if it cannot be resolved successfully.

5.2.2. Version comparison strings

You can define a version range by adding a comparison string to the spec.version field in an Operator or extension’s custom resource (CR). A comparison string is a list of space- or comma-separated values and one or more comparison operators enclosed in double quotation marks ("). You can add another comparison string by including an OR, or double vertical bar (||), comparison operator between the strings.

Table 5.4. Basic comparisons
Comparison operatorDefinition

=

Equal to

!=

Not equal to

>

Greater than

<

Less than

>=

Greater than or equal to

<=

Less than or equal to

You can specify a version range in an Operator or extension’s CR by using a range comparison similar to the following example:

Example version range comparison

apiVersion: olm.operatorframework.io/v1alpha1
kind: ClusterExtension
metadata:
  name: pipelines-operator
spec:
  packageName: openshift-pipelines-operator-rh
  installNamespace: <namespace_name>
  version: ">=1.11, <1.13"

You can use wildcard characters in all types of comparison strings. OLM v1 accepts x, X, and asterisks (*) as wildcard characters. When you use a wildcard character with the equal sign (=) comparison operator, you define a comparison at the patch or minor version level.

Table 5.5. Example wildcard characters in comparison strings
Wildcard comparisonMatching string

1.11.x

>=1.11.0, <1.12.0

>=1.12.X

>=1.12.0

<=2.x

<3

*

>=0.0.0

You can make patch release comparisons by using the tilde (~) comparison operator. Patch release comparisons specify a minor version up to the next major version.

Table 5.6. Example patch release comparisons
Patch release comparisonMatching string

~1.11.0

>=1.11.0, <1.12.0

~1.12

>=1.12, <1.13

~1.12.x

>=1.12.0, <1.13.0

~1.x

>=1, <2

You can use the caret (^) comparison operator to make a comparison for a major release. If you make a major release comparison before the first stable release is published, the minor versions define the API’s level of stability. In the semantic versioning (semver) specification, the first stable release is published as the 1.0.0 version.

^2.3

>= 2.3, < 3

5.2.3. Example custom resources (CRs) that specify a target version

In Operator Lifecycle Manager (OLM) v1, cluster administrators can declaratively set the target version of an Operator or extension in the custom resource (CR).

You can define a target version by specifying any of the following fields:

  • Channel
  • Version number
  • Version range

If you specify a channel in the CR, OLM v1 installs the latest version of the Operator or extension that can be resolved within the specified channel. When updates are published to the specified channel, OLM v1 automatically updates to the latest release that can be resolved from the channel.

Example CR with a specified channel

apiVersion: olm.operatorframework.io/v1alpha1
kind: ClusterExtension
metadata:
  name: pipelines-operator
spec:
  packageName: openshift-pipelines-operator-rh
  installNamespace: <namespace_name>
  serviceAccount:
    name: <service_account>
  channel: latest 1

1
Installs the latest release that can be resolved from the specified channel. Updates to the channel are automatically installed.

If you specify the Operator or extension’s target version in the CR, OLM v1 installs the specified version. When the target version is specified in the CR, OLM v1 does not change the target version when updates are published to the catalog.

If you want to update the version of the Operator that is installed on the cluster, you must manually edit the Operator’s CR. Specifying an Operator’s target version pins the Operator’s version to the specified release.

Example CR with the target version specified

apiVersion: olm.operatorframework.io/v1alpha1
kind: ClusterExtension
metadata:
  name: pipelines-operator
spec:
  packageName: openshift-pipelines-operator-rh
  installNamespace: <namespace_name>
  serviceAccount:
    name: <service_account>
  version: "1.11.1" 1

1
Specifies the target version. If you want to update the version of the Operator or extension that is installed, you must manually update this field the CR to the desired target version.

If you want to define a range of acceptable versions for an Operator or extension, you can specify a version range by using a comparison string. When you specify a version range, OLM v1 installs the latest version of an Operator or extension that can be resolved by the Operator Controller.

Example CR with a version range specified

apiVersion: olm.operatorframework.io/v1alpha1
kind: ClusterExtension
metadata:
  name: pipelines-operator
spec:
  packageName: openshift-pipelines-operator-rh
  installNamespace: <namespace_name>
  serviceAccount:
    name: <service_account>
  version: ">1.11.1" 1

1
Specifies that the desired version range is greater than version 1.11.1. For more information, see "Support for version ranges".

After you create or update a CR, apply the configuration file by running the following command:

Command syntax

$ oc apply -f <extension_name>.yaml

5.2.4. Forcing an update or rollback

OLM v1 does not support automatic updates to the next major version or rollbacks to an earlier version. If you want to perform a major version update or rollback, you must verify and force the update manually.

Warning

You must verify the consequences of forcing a manual update or rollback. Failure to verify a forced update or rollback might have catastrophic consequences such as data loss.

Prerequisites

  • You have a catalog installed.
  • You have an Operator or extension installed.
  • You have created a service account and assigned enough role-based access controls (RBAC) to install, update, and manage the extension you want to install. For more information, see Creating a service account.

Procedure

  1. Edit the custom resource (CR) of your Operator or extension as shown in the following example:

    Example CR

    apiVersion: olm.operatorframework.io/v1alpha1
kind: Operator
metadata:
  name: <operator_name> 1
spec:
  packageName: <package_name> 2
  installNamespace: <namespace_name>
  serviceAccount:
    name: <service_account>
  version: <version> 3
  upgradeConstraintPolicy: Ignore 4

    1
    Specifies the name of the Operator or extension, such as pipelines-operator
    2
    Specifies the package name, such as openshift-pipelines-operator-rh.
    3
    Specifies the blocked update or rollback version.
    4
    Optional: Specifies the upgrade constraint policy. To force an update or rollback, set the field to Ignore. If unspecified, the default setting is Enforce.

  2. Apply the changes to your Operator or extensions CR by running the following command: 

    $ oc apply -f <extension_name>.yaml

5.3. Custom resource definition (CRD) upgrade safety

Important

Operator Lifecycle Manager (OLM) v1 is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

When you update a custom resource definition (CRD) that is provided by a cluster extension, Operator Lifecycle Manager (OLM) v1 runs a CRD upgrade safety preflight check to ensure backwards compatibility with previous versions of that CRD. The CRD update must pass the validation checks before the change is allowed to progress on a cluster.

Additional resources

5.3.1. Prohibited CRD upgrade changes

The following changes to an existing custom resource definition (CRD) are caught by the CRD upgrade safety preflight check and prevent the upgrade:

  • A new required field is added to an existing version of the CRD
  • An existing field is removed from an existing version of the CRD
  • An existing field type is changed in an existing version of the CRD
  • A new default value is added to a field that did not previously have a default value
  • The default value of a field is changed
  • An existing default value of a field is removed
  • New enum restrictions are added to an existing field which did not previously have enum restrictions
  • Existing enum values from an existing field are removed
  • The minimum value of an existing field is increased in an existing version
  • The maximum value of an existing field is decreased in an existing version
  • Minimum or maximum field constraints are added to a field that did not previously have constraints
Note

The rules for changes to minimum and maximum values apply to minimum, minLength, minProperties, minItems, maximum, maxLength, maxProperties, and maxItems constraints.

The following changes to an existing CRD are reported by the CRD upgrade safety preflight check and prevent the upgrade, though the operations are technically handled by the Kubernetes API server:

  • The scope changes from Cluster to Namespace or from Namespace to Cluster
  • An existing stored version of the CRD is removed

If the CRD upgrade safety preflight check encounters one of the prohibited upgrade changes, it logs an error for each prohibited change detected in the CRD upgrade.

Tip

In cases where a change to the CRD does not fall into one of the prohibited change categories, but is also unable to be properly detected as allowed, the CRD upgrade safety preflight check will prevent the upgrade and log an error for an "unknown change".

5.3.2. Allowed CRD upgrade changes

The following changes to an existing custom resource definition (CRD) are safe for backwards compatibility and will not cause the CRD upgrade safety preflight check to halt the upgrade:

  • Adding new enum values to the list of allowed enum values in a field
  • An existing required field is changed to optional in an existing version
  • The minimum value of an existing field is decreased in an existing version
  • The maximum value of an existing field is increased in an existing version
  • A new version of the CRD is added with no modifications to existing versions

5.3.3. Disabling CRD upgrade safety preflight check

The custom resource definition (CRD) upgrade safety preflight check can be disabled by adding the preflight.crdUpgradeSafety.disabled field with a value of true to the ClusterExtension object that provides the CRD.

Warning

Disabling the CRD upgrade safety preflight check could break backwards compatibility with stored versions of the CRD and cause other unintended consequences on the cluster.

You cannot disable individual field validators. If you disable the CRD upgrade safety preflight check, all field validators are disabled.

Note

The following checks are handled by the Kubernetes API server:

  • The scope changes from Cluster to Namespace or from Namespace to Cluster
  • An existing stored version of the CRD is removed

After disabling the CRD upgrade safety preflight check via Operator Lifecycle Manager (OLM) v1, these two operations are still prevented by Kubernetes.

Prerequisites

  • You have a cluster extension installed.

Procedure

  1. Edit the ClusterExtension object of the CRD: 

    $ oc edit clusterextension <clusterextension_name>

  2. Set the preflight.crdUpgradeSafety.disabled field to true:

    Example 5.22. Example ClusterExtension object

    apiVersion: olm.operatorframework.io/v1alpha1
kind: ClusterExtension
metadata:
    name: clusterextension-sample
spec:
    installNamespace: default
    packageName: argocd-operator
    version: 0.6.0
    preflight:
        crdUpgradeSafety:
            disabled: true 1
    1
    Set to true.

5.3.4. Examples of unsafe CRD changes

The following examples demonstrate specific changes to sections of an example custom resource definition (CRD) that would be caught by the CRD upgrade safety preflight check.

For the following examples, consider a CRD object in the following starting state:

Example 5.23. Example CRD object

apiVersion: apiextensions.k8s.io/v1
