Upgrade server v4.x

This page describes the steps needed to upgrade you CircleCI server v4.x installation.

A successful deployment will update the web app. Unless noted in the release notes, updates are rolling updates and there is no downtime.

Note
 We recommend that you do not skip releases when upgrading.

Prerequisites

  • Ensure you have access to the Kubernetes cluster in which server is installed.

  • Ensure you have set up Backup and Restore.

  • Ensure there is a recent backup. For more information, see the Backup and Restore guide.

Upgrade steps

  1. Check the changelog and make sure there are no actions you need to take before deploying a new version.

  2. Optionally, confirm what the update is going to do using Helm Diff:

    helm diff upgrade circleci-server oci://cciserver.azurecr.io/circleci-server -n $namespace --version <version> -f <path-to-values.yaml> --username $USERNAME --password $PASSWORD

  3. Perform the upgrade:

    helm upgrade circleci-server oci://cciserver.azurecr.io/circleci-server -n $namespace --version <version> -f <path-to-values.yaml> --username $USERNAME --password $PASSWORD

  4. Deploy and run reality check in your test environment to ensure your installation is fully operational.
