Defines the way in which the workspace plugins and editors are exposed in the single-host mode. Supported exposures: - 'native': Exposes servers using OpenShift Ingresses. Works only on OpenShift.

CHE_INFRA_KUBERNETES_INGRESS_DOMAIN

Used to generate domain for a server in a workspace in case property che.infra.kubernetes.server_strategy is set to multi-host

CHE_INFRA_KUBERNETES_NAMESPACE

DEPRECATED - please do not change the value of this property otherwise the existing workspaces will loose data. Do not set it on new installations. Defines OpenShift namespace in which all workspaces will be created. If not set, every workspace will be created in a new namespace, where namespace = workspace id It’s possible to use <username> and <userid> placeholders (e.g.: che-workspace-<username>). In that case, new namespace will be created for each user. Service account with permission to create new namespace must be used. Ignored for OpenShift infra. Use che.infra.openshift.project instead If the namespace pointed to by this property exists, it will be used for all workspaces. If it does not exist, the namespace specified by the che.infra.kubernetes.namespace.default will be created and used.

CHE_INFRA_KUBERNETES_NAMESPACE_DEFAULT

<username>-che

Defines OpenShift default namespace in which user’s workspaces are created if user does not override it. It’s possible to use <username>, <userid> and <workspaceid> placeholders (e.g.: che-workspace-<username>). In that case, new namespace will be created for each user (or workspace). Is used by OpenShift infra as well to specify Project

CHE_INFRA_KUBERNETES_NAMESPACE_ALLOW__USER__DEFINED

false

Defines if a user is able to specify OpenShift namespace (or OpenShift project) different from the default. It’s NOT RECOMMENDED to configured true without OAuth configured. This property is also used by the OpenShift infra.

CHE_INFRA_KUBERNETES_SERVICE__ACCOUNT__NAME

NULL

Defines OpenShift Service Account name which should be specified to be bound to all workspaces pods. Note that OpenShift Infrastructure won’t create the service account and it should exist. OpenShift infrastructure will check if project is predefined(if che.infra.openshift.project is not empty): - if it is predefined then service account must exist there - if it is 'NULL' or empty string then infrastructure will create new OpenShift project per workspace and prepare workspace service account with needed roles there

CHE_INFRA_KUBERNETES_WORKSPACE__SA__CLUSTER__ROLES

NULL

Specifies optional, additional cluster roles to use with the workspace service account. Note that the cluster role names must already exist, and the CodeReady Workspaces service account needs to be able to create a Role Binding to associate these cluster roles with the workspace service account. The names are comma separated. This property deprecates 'che.infra.kubernetes.cluster_role_name'.

CHE_INFRA_KUBERNETES_WORKSPACE__START__TIMEOUT__MIN

8

Defines time frame that limits the OpenShift workspace start time

CHE_INFRA_KUBERNETES_INGRESS__START__TIMEOUT__MIN

Defines the timeout in minutes that limits the period for which OpenShift Ingress become ready

CHE_INFRA_KUBERNETES_WORKSPACE__UNRECOVERABLE__EVENTS

FailedMount,FailedScheduling,MountVolume.SetUpfailed,Failed to pull image,FailedCreate

If during workspace startup an unrecoverable event defined in the property occurs, terminate workspace immediately instead of waiting until timeout Note that this SHOULD NOT include a mere 'Failed' reason, because that might catch events that are not unrecoverable. A failed container startup is handled explicitly by CodeReady Workspaces server.

CHE_INFRA_KUBERNETES_PVC_ENABLED

true

Defines whether use the Persistent Volume Claim for che workspace needs e.g backup projects, logs etc or disable it.

CHE_INFRA_KUBERNETES_PVC_STRATEGY

common

Defined which strategy will be used while choosing PVC for workspaces. Supported strategies: - 'common' All workspaces in the same OpenShift Namespace will reuse the same PVC. Name of PVC may be configured with 'che.infra.kubernetes.pvc.name'. Existing PVC will be used or new one will be created if it doesn’t exist. - 'unique' Separate PVC for each workspace’s volume will be used. Name of PVC is evaluated as '{che.infra.kubernetes.pvc.name} + '-' + `{generated_8_chars}’. Existing PVC will be used or a new one will be created if it doesn’t exist. - 'per-workspace' Separate PVC for each workspace will be used. Name of PVC is evaluated as '{che.infra.kubernetes.pvc.name} + '-' + `{WORKSPACE_ID}’. Existing PVC will be used or a new one will be created if it doesn’t exist.

CHE_INFRA_KUBERNETES_PVC_PRECREATE__SUBPATHS

true

Defines whether to run a job that creates workspace’s subpath directories in persistent volume for the 'common' strategy before launching a workspace. Necessary in some versions of OpenShift/OpenShift as workspace subpath volume mounts are created with root permissions, and thus cannot be modified by workspaces running as a user (presents an error importing projects into a workspace in CodeReady Workspaces). The default is 'true', but should be set to false if the version of Openshift/OpenShift creates subdirectories with user permissions. Relevant issue: https://github.com/kubernetes/kubernetes/issues/41638 Note that this property has effect only if the 'common' PVC strategy used.

CHE_INFRA_KUBERNETES_PVC_NAME

claim-che-workspace

Defines the settings of PVC name for che workspaces. Each PVC strategy supplies this value differently. See doc for che.infra.kubernetes.pvc.strategy property

CHE_INFRA_KUBERNETES_PVC_STORAGE__CLASS__NAME

Defines the storage class of Persistent Volume Claim for the workspaces. Empty strings means 'use default'.

CHE_INFRA_KUBERNETES_PVC_QUANTITY

10Gi

Defines the size of Persistent Volume Claim of che workspace. Format described here: https://docs.openshift.com/container-platform/4.4/storage/understanding-persistent-storage.html

CHE_INFRA_KUBERNETES_PVC_JOBS_MEMORYLIMIT

250Mi

Defines pod memory limit for persistent volume claim maintenance jobs

CHE_INFRA_KUBERNETES_PVC_ACCESS__MODE

ReadWriteOnce

Defines Persistent Volume Claim access mode. Note that for common PVC strategy changing of access mode affects the number of simultaneously running workspaces. If OpenShift flavor where che running is using PVs with RWX access mode then a limit of running workspaces at the same time bounded only by che limits configuration like(RAM, CPU etc). Detailed information about access mode is described here: https://docs.openshift.com/container-platform/4.4/storage/understanding-persistent-storage.html

CHE_INFRA_KUBERNETES_PVC_WAIT__BOUND

true

Defines whether CodeReady Workspaces Server should wait workspaces PVCs to become bound after creating. It’s used by all PVC strategies. It should be set to false in case if volumeBindingMode is configured to WaitForFirstConsumer otherwise workspace starts will hangs up on phase of waiting PVCs. Default value is true (means that PVCs should be waited to be bound)

CHE_INFRA_KUBERNETES_INSTALLER__SERVER__MIN__PORT

10000

Defined range of ports for installers servers By default, installer will use own port, but if it conflicts with another installer servers then OpenShift infrastructure will reconfigure installer to use first available from this range

CHE_INFRA_KUBERNETES_INSTALLER__SERVER__MAX__PORT

20000

Definedrange of ports for installers servers By default, installer will use own port, but if it conflicts with another installer servers then OpenShift infrastructure will reconfigure installer to use first available from this range

CHE_INFRA_KUBERNETES_INGRESS_ANNOTATIONS__JSON

NULL

Defines annotations for ingresses which are used for servers exposing. Value depends on the kind of ingress controller. OpenShift infrastructure ignores this property because it uses Routes instead of ingresses. Note that for a single-host deployment strategy to work, a controller supporting URL rewriting has to be used (so that URLs can point to different servers while the servers don’t need to support changing the app root). The che.infra.kubernetes.ingress.path.rewrite_transform property defines how the path of the ingress should be transformed to support the URL rewriting and this property defines the set of annotations on the ingress itself that instruct the chosen ingress controller to actually do the URL rewriting, potentially building on the path transformation (if required by the chosen ingress controller). For example for nginx ingress controller 0.22.0 and later the following value is recommended: {'ingress.kubernetes.io/rewrite-target': '/$1','ingress.kubernetes.io/ssl-redirect': 'false',\ 'ingress.kubernetes.io/proxy-connect-timeout': '3600','ingress.kubernetes.io/proxy-read-timeout': '3600'} and the che.infra.kubernetes.ingress.path.rewrite_transform should be set to '%s(.*)' For nginx ingress controller older than 0.22.0, the rewrite-target should be set to merely '/' and the path transform to '%s' (see the the che.infra.kubernetes.ingress.path.rewrite_transform property). Please consult the nginx ingress controller documentation for the explanation of how the ingress controller uses the regular expression present in the ingress path and how it achieves the URL rewriting.

CHE_INFRA_KUBERNETES_INGRESS_PATH__TRANSFORM

NULL

Defines a 'recipe' on how to declare the path of the ingress that should expose a server. The '%s' represents the base public URL of the server and is guaranteed to end with a forward slash. This property must be a valid input to the String.format() method and contain exactly one reference to '%s'. Please see the description of the che.infra.kubernetes.ingress.annotations_json property to see how these two properties interplay when specifying the ingress annotations and path. If not defined, this property defaults to '%s' (without the quotes) which means that the path is not transformed in any way for use with the ingress controller.

CHE_INFRA_KUBERNETES_POD_SECURITY__CONTEXT_RUN__AS__USER

NULL

Defines security context for pods that will be created by OpenShift Infra This is ignored by OpenShift infra

CHE_INFRA_KUBERNETES_POD_SECURITY__CONTEXT_FS__GROUP

NULL

Definessecurity context for pods that will be created by OpenShift Infra This is ignored by OpenShift infra

CHE_INFRA_KUBERNETES_POD_TERMINATION__GRACE__PERIOD__SEC

0

Defines grace termination period for pods that will be created by OpenShift / OpenShift infrastructures Grace termination period of OpenShift / OpenShift workspace’s pods defaults '0', which allows to terminate pods almost instantly and significantly decrease the time required for stopping a workspace. Note: if terminationGracePeriodSeconds have been explicitly set in OpenShift / OpenShift recipe it will not be overridden.

CHE_INFRA_KUBERNETES_CLIENT_HTTP_ASYNC__REQUESTS_MAX

1000

Number of maximum concurrent async web requests (http requests or ongoing web socket calls) supported in the underlying shared http client of the OpenShiftClient instances. Default values are 64, and 5 per-host, which doesn’t seem correct for multi-user scenarios knowing that CodeReady Workspaces keeps a number of connections opened (e.g. for command or ws-agent logs)

CHE_INFRA_KUBERNETES_CLIENT_HTTP_ASYNC__REQUESTS_MAX__PER__HOST

1000

Numberof maximum concurrent async web requests (http requests or ongoing web socket calls) supported in the underlying shared http client of the OpenShiftClient instances. Default values are 64, and 5 per-host, which doesn’t seem correct for multi-user scenarios knowing that {prod-short} keeps a number of connections opened (e.g. for command or ws-agent logs)

CHE_INFRA_KUBERNETES_CLIENT_HTTP_CONNECTION__POOL_MAX__IDLE

5

Max number of idle connections in the connection pool of the OpenShift-client shared http client

CHE_INFRA_KUBERNETES_TLS__CERT

NULL

Datafor TLS Secret that should be used for workspaces Ingresses cert and key should be encoded with Base64 algorithm These properties are ignored by OpenShift infrastructure

CHE_INFRA_KUBERNETES_RUNTIMES__CONSISTENCY__CHECK__PERIOD__MIN

-1

Defines the period with which runtimes consistency checks will be performed. If runtime has inconsistent state then runtime will be stopped automatically. Value must be more than 0 or -1, where -1 means that checks won’t be performed at all. It is disabled by default because there is possible CodeReady Workspaces Server configuration when CodeReady Workspaces Server doesn’t have an ability to interact with OpenShift API when operation is not invoked by user. It DOES work on the following configurations: - workspaces objects are created in the same namespace where CodeReady Workspaces Server is located; - cluster-admin service account token is mount to CodeReady Workspaces Server pod; It DOES NOT work on the following configurations: - CodeReady Workspaces Server communicates with OpenShift API using token from OAuth provider;

CHE_INFRA_OPENSHIFT_PROJECT

DEPRECATED - please do not change the value of this property otherwise the existing workspaces will loose data. Do not set it on new installations. Defines OpenShift namespace in which all workspaces will be created. If not set, every workspace will be created in a new project, where project name = workspace id It’s possible to use <username> and <userid> placeholders (e.g.: che-workspace-<username>). In that case, new project will be created for each user. OpenShift oauth or service account with permission to create new projects must be used. If the project pointed to by this property exists, it will be used for all workspaces. If it does not exist, the namespace specified by the che.infra.kubernetes.namespace.default will be created and used.

CHE_INFRA_OPENSHIFT_TRUSTED__CA__BUNDLES__CONFIG__MAP

ca-certs

Configures name of the trust-store config map where the CA bundles are stored in Openshift 4. This map is supposed to be initially created by CodeReady Workspaces installer (operator or etc) with basically any name, and CodeReady Workspaces server finds it by specific label (see below) during workspace startup and then creates and mounts same map in the namespace of the workspace. The property defines name of the map in workspace namespace.
