Chapter 3. Installing CodeReady Workspaces

This section contains instructions to install Red Hat CodeReady Workspaces. The installation method depends on the target platform and the environment restrictions.

3.1. Installing CodeReady Workspaces on OpenShift 4 using OperatorHub

This section describes how to install CodeReady Workspaces using the CodeReady Workspaces Operator available in OpenShift 4 web console.

Operators are a method of packaging, deploying, and managing an OpenShift application which also provide the following:

  • Repeatability of installation and upgrade.
  • Constant health checks of every system component.
  • Over-the-air (OTA) updates for OpenShift components and independent software vendor (ISV) content.
  • A place to encapsulate knowledge from field engineers and spread it to all users.

Prerequisites

  • An administrator account on a running instance of OpenShift 4.

3.1.1. Installing the Red Hat CodeReady Workspaces Operator

Red Hat CodeReady Workspaces Operator provides all the resources for running CodeReady Workspaces, such as PostgreSQL, RH-SSO, image registries, and the CodeReady Workspaces server, and it also configures all these services.

  2. Click codeready-workspaces CheCluster and navigate to the Details tab.
  3. See the content of the following fields:

    • The Message field contains error messages. The expected content is None.
    • The Red Hat CodeReady Workspaces URL field contains the URL of the Red Hat CodeReady Workspaces instance. The URL appears when the deployment finishes successfully.
  4. Navigate to the Resources tab. View the list of resources assigned to the CodeReady Workspaces deployment and their status.

3.2. Installing CodeReady Workspaces on OpenShift 4 using the CLI

This section describes how to install CodeReady Workspaces on OpenShift 4 with the crwctl CLI management tool.

Prerequisites

Procedure

  • Run the server:deploy command to create the CodeReady Workspaces instance:

    $ crwctl server:deploy -n openshift-workspaces

Verification steps

  1. The output of the server:deploy command ends with:

    Command server:deploy has completed successfully.
  2. Navigate to the CodeReady Workspaces cluster instance: \https://codeready-<openshift_deployment_name>.<domain_name>.

3.3. Installing CodeReady Workspaces on OpenShift Container Platform 3.11

3.3.1. Installing the crwctl CLI management tool

This section describes how to install crwctl, the CodeReady Workspaces CLI management tool.

Procedure

  1. Navigate to https://developers.redhat.com/products/codeready-workspaces/download.
  2. Download the CodeReady Workspaces CLI management tool archive for version 2.13.
  3. Extract the archive to a folder, such as $HOME/crwctl or /opt/crwctl.
  4. Run the crwctl executable from the extracted folder. In this example, $HOME/crwctl/bin/crwctl version.
  5. Optionally, add the bin folder to your $PATH, for example, PATH=$PATH:$HOME/crwctl/bin to enable running crwctl without the full path specification.

Verification step

Running crwctl version displays the current version of the tool.

3.3.2. Installing CodeReady Workspaces on OpenShift 3 using the Operator

This section describes how to install CodeReady Workspaces on OpenShift 3 with the crwctl CLI management tool. The method of installation is using the Operator and enable TLS (HTTPS).

Operators are a method of packaging, deploying, and managing a OpenShift application which also provide the following:

  • Repeatability of installation and upgrade.
  • Constant health checks of every system component.
  • Over-the-air (OTA) updates for OpenShift components and independent software vendor (ISV) content.
  • A place to encapsulate knowledge from field engineers and spread it to all users.
Note

This approach is only supported for use with OpenShift Container Platform and OpenShift Dedicated version 3.11, but also work for newer versions of OpenShift Container Platform and OpenShift Dedicated, and serves as a backup installation method for situations when the installation method using OperatorHub is not available.

Prerequisites

Procedure

  1. Log in to OpenShift. See Basic Setup and Login.

    $ oc login
  2. Run the following command to verify that the version of the oc OpenShift CLI management tool is 3.11:

    $ oc version
    oc v3.11.0+0cbc58b
  3. Run the following command to create the CodeReady Workspaces instance in the default project called openshift-workspaces:

    $ crwctl server:deploy -p openshift

Verification steps

  1. The output of the previous command ends with:

    Command server:deploy has completed successfully.
  2. Navigate to the CodeReady Workspaces cluster instance: \https://codeready-<openshift_deployment_name>.<domain_name>.

3.4. Installing CodeReady Workspaces in a restricted environment

By default, Red Hat CodeReady Workspaces uses various external resources, mainly container images available in public registries.

To deploy CodeReady Workspaces in an environment where these external resources are not available (for example, on a cluster that is not exposed to the public Internet):

  1. Identify the image registry used by the OpenShift cluster, and ensure you can push to it.
  2. Push all the images needed for running CodeReady Workspaces to this registry.
  3. Configure CodeReady Workspaces to use the images that have been pushed to the registry.
  4. Proceed to the CodeReady Workspaces installation.

The procedure for installing CodeReady Workspaces in restricted environments is different based on the installation method you use:

Notes on network connectivity in restricted environments

Restricted network environments range from a private subnet in a cloud provider to a separate network owned by a company, disconnected from the public Internet. Regardless of the network configuration, CodeReady Workspaces works provided that the Routes that are created for CodeReady Workspaces components (codeready-workspaces-server, identity provider, devfile and plugin registries) are accessible from inside the OpenShift cluster.

Take into account the network topology of the environment to determine how best to accomplish this. For example, on a network owned by a company or an organization, the network administrators must ensure that traffic bound from the cluster can be routed to Route hostnames. In other cases, for example, on AWS, create a proxy configuration allowing the traffic to leave the node to reach an external-facing Load Balancer.

When the restricted network involves a proxy, follow the instructions provided in Section 3.4.3, “Preparing CodeReady Workspaces Custom Resource for installing behind a proxy”.

3.4.1. Installing CodeReady Workspaces in a restricted environment using OperatorHub

Prerequisites

On disconnected OpenShift 4 clusters running on restricted networks, an Operator can be successfully installed from OperatorHub only if it meets the additional requirements defined in Enabling your Operator for restricted network environments.

The CodeReady Workspaces operator meets these requirements and is therefore compatible with the official documentation about OLM on a restricted network.

Procedure

To install CodeReady Workspaces from OperatorHub:

  1. Build a redhat-operators catalog image. See Building an Operator catalog image.
  2. Configure OperatorHub to use this catalog image for operator installations. See Configuring OperatorHub for restricted networks.
  3. Proceed to the CodeReady Workspaces installation as usual as described in Section 3.1, “Installing CodeReady Workspaces on OpenShift 4 using OperatorHub”.

3.4.2. Installing CodeReady Workspaces in a restricted environment using CLI management tool

Note

Use CodeReady Workspaces CLI management tool to install CodeReady Workspaces on restricted networks if installation through OperatorHub is not available. This method is supported for OpenShift Container Platform 3.11.

Prerequisites

3.4.2.1. Preparing an private registry

Prerequisites

  • The oc tool is available.
  • The skopeo tool, version 0.1.40 or later, is available.
  • The podman tool is available.
  • An image registry accessible from the OpenShift cluster and supporting the format of the V2 image manifest, schema version 2. Ensure you can push to it from a location having, at least temporarily, access to the internet.

Table 3.1. Placeholders used in examples

<source-image>

Full coordinates of the source image, including registry, organization, and digest.

<target-registry>

Host name and port of the target container-image registry.

<target-organization>

Organization in the target container-image registry

<target-image>

Image name and digest in the target container-image registry.

<target-user>

User name in the target container-image registry.

<target-password>

User password in the target container-image registry.

Procedure

  1. Log into the internal image registry:

    $ podman login --username <user> --password <password> <target-registry>
    Note

    If you encounter an error, like x509: certificate signed by unknown authority, when attempting to push to the internal registry, try one of these workarounds:

    • add the OpenShift cluster’s certificate to /etc/containers/certs.d/<target-registry>
    • add the registry as an insecure registry by adding the following lines to the Podman configuration file located at /etc/containers/registries.conf:
    [registries.insecure]
    registries = ['<target-registry>']
  2. Copy images without changing their digest. Repeat this step for every image in the following table:

    $ skopeo copy --all docker://<source-image> docker://<target-registry>/<target-organization>/<target-image>
    Note

3.4.2.2. Preparing CodeReady Workspaces Custom Resource for restricted environment

When installing CodeReady Workspaces in a restricted environment using crwctl or OperatorHub, provide a CheCluster custom resource with additional information.

3.4.2.2.1. Downloading the default CheCluster Custom Resource

Procedure

  1. Download the default custom resource YAML file.
  2. Name the downloaded custom resource org_v1_che_cr.yaml. Keep it for further modification and usage.
3.4.2.2.2. Customizing the CheCluster Custom Resource for restricted environment

Prerequisites

  • All required images available in an image registry that is visible to the OpenShift cluster where CodeReady Workspaces is to be deployed. This is described in Section 3.4.2.1, “Preparing an private registry”, where the placeholders used in the following examples are also defined.

Procedure

  1. In the CheCluster Custom Resource, which is managed by the CodeReady Workspaces Operator, add the fields used to facilitate deploying an instance of CodeReady Workspaces in a restricted environment:

    # [...]
    spec:
      server:
        airGapContainerRegistryHostname: '<target-registry>'
        airGapContainerRegistryOrganization: '<target-organization>'
    # [...]

3.4.2.3. Starting CodeReady Workspaces installation in a restricted environment using CodeReady Workspaces CLI management tool

This sections describes how to start the CodeReady Workspaces installation in a restricted environment using the CodeReady Workspaces CLI management tool.

Prerequisites

Procedure

  1. Log in to OpenShift Container Platform:

    $ oc login ${OPENSHIFT_API_URL} --username ${OPENSHIFT_USERNAME} \
                                    --password ${OPENSHIFT_PASSWORD}
  2. Install CodeReady Workspaces with a customized Custom Resource to add fields related to the restricted environment:

    $ crwctl server:start \
      --che-operator-image=<target-registry>/<target-organization>/crw-2-rhel8-operator:2.13 \
      --che-operator-cr-yaml=org_v1_che_cr.yaml
Note

For slow systems or internet connections, add the --k8spodwaittimeout=1800000 flag option to the crwctl server:start command to extend the Pod timeout period to 1800000 ms or longer.

3.4.3. Preparing CodeReady Workspaces Custom Resource for installing behind a proxy

This procedure describes how to provide necessary additional information to the CheCluster custom resource when installing CodeReady Workspaces behind a proxy.

Procedure

  1. In the CheCluster Custom Resource, which is managed by the CodeReady Workspaces Operator, add the fields used to facilitate deploying an instance of CodeReady Workspaces in a restricted environment:

    # [...]
    spec:
      server:
        proxyURL: '<URL of the proxy, with the http protocol, and without the port>'
        proxyPort: '<Port of proxy, typically 3128>'
    # [...]
  2. In addition to those basic settings, the proxy configuration usually requires adding the host of the external OpenShift cluster API URL in the list of the hosts to be accessed from CodeReady Workspaces without using the proxy.

    To retrieve this cluster API host, run the following command against the OpenShift cluster:

    $ oc whoami --show-server | sed 's#https://##' | sed 's#:.*$##'

    The corresponding field of the CheCluster Custom Resource is nonProxyHosts. If a host already exists in this field, use | as a delimiter to add the cluster API host:

    # [...]
    spec:
      server:
        nonProxyHosts: 'anotherExistingHost|<cluster api host>'
    # [...]
