Chapter 5. Upgrading CodeReady Workspaces

This chapter describes how to upgrade a CodeReady Workspaces instance from version 2.10 to CodeReady Workspaces 2.11.

The method used to install the CodeReady Workspaces instance determines the method to proceed with for the upgrade:

5.1. Upgrading CodeReady Workspaces using OperatorHub

This section describes how to upgrade from an earlier minor version using the Operator from OperatorHub in the OpenShift web console.

OperatorHub supports Automatic and Manual upgrade strategies: Automatic:: The upgrade process starts when a new version of the Operator is published. Manual:: The update must be manually approved every time the new version of the Operator is published.

5.1.1. Specifying the approval strategy of CodeReady Workspaces in OperatorHub

Prerequisites

  • An administrator account on an OpenShift instance.
  • An instance of an earlier minor version of CodeReady Workspaces, installed using the Operator from OperatorHub on the same instance of OpenShift.

5.2. Upgrading CodeReady Workspaces using the CLI management tool

This section describes how to upgrade from the previous minor version using the CLI management tool.

Prerequisites

  • An administrative account on OpenShift.
  • A running instance of a previous minor version of Red Hat CodeReady Workspaces, installed using the CLI management tool on the same instance of OpenShift, in the <openshift-workspaces> project.
  • crwctl is available and updated. See Section 3.3.1, “Installing the crwctl CLI management tool”.

Procedure

  1. Save and push changes back to the Git repositories for all running CodeReady Workspaces 2.10 workspaces.
  2. Shut down all workspaces in the CodeReady Workspaces 2.10 instance.
  3. Upgrade CodeReady Workspaces:

    $ crwctl server:update -n openshift-workspaces
Note

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

Verification steps

  1. Navigate to the CodeReady Workspaces instance.
  2. The 2.11 version number is visible at the bottom of the page.

5.3. Upgrading CodeReady Workspaces using the CLI management tool in restricted environment

This section describes how to upgrade Red Hat CodeReady Workspaces using the CLI management tool in restricted environment. The upgrade path supports minor version update, from CodeReady Workspaces version 2.10 to version 2.11.

Prerequisites

5.3.1. Understanding network connectivity in restricted environments

CodeReady Workspaces requires that each OpenShift Route created for CodeReady Workspaces is accessible from inside the OpenShift cluster. These CodeReady Workspaces components have a OpenShift Route: codeready-workspaces-server, keycloak, devfile-registry, plugin-registry.

Consider the network topology of the environment to determine how best to accomplish this.

Example 5.1. Network owned by a company or an organization, disconnected from the public Internet

The network administrators must ensure that it is possible to route traffic bound from the cluster to OpenShift Route host names.

Example 5.2. Private subnetwork in a cloud provider

Create a proxy configuration allowing the traffic to leave the node to reach an external-facing Load Balancer.

5.3.2. Building offline registry images

5.3.2.1. Building an offline devfile registry image

This section describes how to build an offline devfile registry image. Starting workspaces without relying on resources from the outside Internet requires building this image. The image contains all sample projects referenced in devfiles as zip files.

Prerequisites:

Procedure

  1. Clone the devfile registry repository and check out the version to deploy:

    $ git clone git@github.com:redhat-developer/codeready-workspaces.git
    $ cd codeready-workspaces
    $ git checkout crw-2.11-rhel-8
  2. Build an offline devfile registry image:

    $ cd dependencies/che-devfile-registry
    $ ./build.sh --organization <my-org> \
               --registry <my-registry> \
               --tag <my-tag> \
               --offline
    Note

    To display full options for the build.sh script, use the --help parameter.

5.3.2.2. Building an offline plug-in registry image

This section describes how to build an offline plug-in registry image. Starting workspaces without relying on resources from the outside Internet requires building this image. The image contains plug-in metadata and all plug-in or extension artifacts.

Prerequisites

  • NodeJS 12.x
  • A running version of yarn. See Installing Yarn.
  • ./node_modules/.bin is in the PATH environment variable.
  • A running installation of podman or docker.

Procedure

  1. Clone the plug-in registry repository and check out the version to deploy:

    $ git clone git@github.com:redhat-developer/codeready-workspaces.git
    $ cd codeready-workspaces
    $ git checkout crw-2.11-rhel-8
  2. Build offline plug-in registry image:

    $ cd dependencies/che-plugin-registry
    $ ./build.sh --organization <my-org> \
               --registry <my-registry> \
               --tag <my-tag> \
               --offline \
               --skip-digest-generation
    Note

    To display full options for the build.sh script, use the --help parameter.

5.3.3. 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 5.1. 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

    Table 5.2. Understanding the usage of the container-images from the prefix or keyword they include in their name

    UsagePrefix or keyword

    Essential

    not stacks-, plugin-, or -openj9-

    Workspaces

    stacks-, plugin-

    IBM Z and IBM Power Systems

    -openj9-

    Note

    Images suffixed with openj9 are the Eclipse OpenJ9 image equivalents of the OpenJDK images used on x86_64. IBM Power Systems and IBM Z use Eclipse OpenJ9 for better performance on those systems.

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

5.4. Upgrading CodeReady Workspaces that uses project strategies other than 'per user'

This section describes how to upgrade CodeReady Workspaces that uses project strategies other than 'per user'.

CodeReady Workspaces intends to use Kubernetes secrets as a storage for all sensitive user data. One project per user simplifies the design of the workspaces. This is the reason why project strategies other than per user become deprecated. The deprecation process happens in two steps. In the First Step project strategies other than per user are allowed but not recommended. In the Second Step support for project strategies other than per user is going to be removed.

Note

No automated upgrade support exists between First Step and Second Step for the installations where project strategies other than per user are used without losing data.

Prerequisites

  • CodeReady Workspaces configured with the project strategies other than per user.
  • Intention to use CodeReady Workspaces configured with the per user namespace strategies per user.

5.4.1. Upgrading CodeReady Workspaces and backing up user data

Procedure

  1. Notify all CodeReady Workspaces users about the upcoming data wipe.

    Note

    To back up the data, you can commit workspace configuration to an SCM server and use factories to restore it later.

  2. Re-install CodeReady Workspaces with per user namespace strategy.

5.4.2. Upgrading CodeReady Workspaces and losing user data

When CodeReady Workspaces is upgraded and user data is not backed up, workspace configuration and user preferences are going to be preserved but all runtime data will be wiped out.

Procedure

  1. Notify all CodeReady Workspaces users about the upcoming data wipe.
  2. Change project strategy to per user.
Note

Upgrading without backing up user data has disadvantage. Original PVs with runtime data are going to be preserved and will no longer be used. This may lead to the waste of resources.
