Chapter 2. Installing Dev Spaces


This section contains instructions to install Red Hat OpenShift Dev Spaces.

You can deploy only one instance of OpenShift Dev Spaces per cluster.

2.1. Installing Dev Spaces on OpenShift using CLI

You can install OpenShift Dev Spaces on OpenShift.

Prerequisites

Procedure

  1. Optional: If you previously deployed OpenShift Dev Spaces on this OpenShift cluster, ensure that the previous OpenShift Dev Spaces instance is removed:

    $ dsc server:delete
  2. Create the OpenShift Dev Spaces instance:

    $ dsc server:deploy --platform openshift

Verification steps

  1. Verify the OpenShift Dev Spaces instance status:

    $ dsc server:status
  2. Navigate to the OpenShift Dev Spaces cluster instance:

    $ dsc dashboard:open

2.2. Installing Dev Spaces on OpenShift using the web console

If you have trouble installing OpenShift Dev Spaces on the command line, you can install it through the OpenShift web console.

Prerequisites

Procedure

  1. In the Administrator view of the OpenShift web console, go to Operators OperatorHub and search for Red Hat OpenShift Dev Spaces.
  2. Install the Red Hat OpenShift Dev Spaces Operator.

    Tip
    Caution

    The Red Hat OpenShift Dev Spaces Operator depends on the Dev Workspace Operator. If you install the Red Hat OpenShift Dev Spaces Operator manually to a non-default namespace, ensure that the Dev Workspace Operator is also installed in the same namespace. This is required as the Operator Lifecycle Manager will attempt to install the Dev Workspace Operator as a dependency within the Red Hat OpenShift Dev Spaces Operator namespace, potentially resulting in two conflicting installations of the Dev Workspace Operator if the latter is installed in a different namespace.

  3. Create the openshift-devspaces project in OpenShift as follows:

    oc create namespace openshift-devspaces
  4. Go to Operators Installed Operators Red Hat OpenShift Dev Spaces instance Specification Create CheCluster YAML view.
  5. In the YAML view, replace namespace: openshift-operators with namespace: openshift-devspaces.
  6. Select Create.

    Tip

Verification

  1. In Red Hat OpenShift Dev Spaces instance Specification, go to devspaces, landing on the Details tab.

  1. Under Message, check that there is None, which means no errors.
  2. Under Red Hat OpenShift Dev Spaces URL, wait until the URL of the OpenShift Dev Spaces instance appears, and then open the URL to check the OpenShift Dev Spaces dashboard.
  3. In the Resources tab, view the resources for the OpenShift Dev Spaces deployment and their status.

2.3. Installing Dev Spaces in a restricted environment

On an OpenShift cluster operating in a restricted network, public resources are not available.

However, deploying OpenShift Dev Spaces and running workspaces requires the following public resources:

  • Operator catalog
  • Container images
  • Sample projects

To make these resources available, you can replace them with their copy in a registry accessible by the OpenShift cluster.

Prerequisites

Procedure

  1. Download and execute the mirroring script to install a custom Operator catalog and mirror the related images: prepare-restricted-environment.sh.

    $ bash prepare-restricted-environment.sh \
      --devworkspace_operator_index registry.redhat.io/redhat/redhat-operator-index:v4.13\
      --devworkspace_operator_version "v0.21.0" \
      --prod_operator_index "registry.redhat.io/redhat/redhat-operator-index:v4.13" \
      --prod_operator_package_name "devspaces" \
      --prod_operator_bundle_name "devspacesoperator" \
      --prod_operator_version "v3.8.0" \
      --my_registry "<my_registry>" 1
    1
    The private Docker registry where the images will be mirrored
  2. Install OpenShift Dev Spaces with the configuration set in the che-operator-cr-patch.yaml during the previous step:

    $ dsc server:deploy \
      --platform=openshift \
      --olm-channel stable \
      --catalog-source-name=devspaces-disconnected-install \
      --catalog-source-namespace=openshift-marketplace \
      --skip-devworkspace-operator \
      --che-operator-cr-patch-yaml=che-operator-cr-patch.yaml
  3. Allow incoming traffic from the OpenShift Dev Spaces namespace to all Pods in the user projects. See: Section 3.7.1, “Configuring network policies”.

2.4. Finding the fully qualified domain name (FQDN)

You can get the fully qualified domain name (FQDN) of your organization’s instance of OpenShift Dev Spaces on the command line or in the OpenShift web console.

Tip

You can find the FQDN for your organization’s OpenShift Dev Spaces instance in the Administrator view of the OpenShift web console as follows. Go to Operators OperatorHub Installed Operators Red Hat OpenShift Dev Spaces instance Specification devspaces Red Hat OpenShift Dev Spaces URL.

Prerequisites

Procedure

  1. Run the following command:

    $ dsc server:status
  2. Copy the Red Hat OpenShift Dev Spaces URL without the trailing /dashboard/.
