This guide will show you how to update your Coder deployment.


  • If you haven't already, install Helm.

  • Before beginning the update process, ensure that you've added the Coder Helm repo to your cluster. You can verify that the Coder repo has been added to Helm using helm repo list:

    $ helm repo list

    If you don't have the Coder repo, you can add it:

    helm repo add coder
  • Ensure that you have superuser privileges to your PostgreSQL database.


  • As with any significant maintenance operation, we strongly recommend taking a snapshot of the database before proceeding with the upgrade. In the event that there are upgrade issues, it is simpler and safer to roll back directly at the database level, since it guarantees restoration of the system to a known working condition.

  • We recommend updating no more than one major version at a time (i.e., we recommend moving from 1.15 to 1.16 only).

Update Coder

To update Coder, follow these steps:

  1. Retrieve the latest repository information:

    helm repo update
  2. Export your current Helm chart values into a file:

    helm get values --namespace coder coder > current-values.yaml

    Make sure that your values only contain the changes you want (i.e., if you see references to a prior version, you may need to remove these).

  3. Provide your Helm chart values file and upgrade to the desired version (e.g., 1.16.1):

    Note: If you omit --version, you'll upgrade to the latest version.

    helm upgrade --namespace coder --install --atomic --wait \
      --version 1.16.1 coder coder/coder --values current-values.yaml

Fixing a failed upgrade

While upgrading, the process may fail. You'll see an error message similar to the following samples indicating that a field is immutable or that Helm doesn't control a resource:

failed to replace object: Service "cemanager" is invalid:
spec.clusterIP: Invalid value: "": field is immutable
Error: UPGRADE FAILED: rendered manifests contain a resource
that already exists. Unable to continue with update:
ServiceAccount "coder" in namespace "coder" exists and cannot
be imported into the current release: invalid ownership metadata;
label validation error: missing key
"": must be set to "Helm"; annotation
validation error: missing key "": must
be set to "coder"; annotation validation error: missing key
"": must be set to "coder"

If this happens, we recommend uninstalling and reinstalling:

  1. Export the Helm chart values into a file:

    helm get values --namespace coder coder > current-values.yaml

    Double-check your values file to ensure it only contains your changes.

  2. Run helm uninstall. This will uninstall all Coder-related services on the cluster (though it preserves the namespaces). It will not delete user workspaces or their associated volumes.

    helm uninstall will delete the timescale instance internal to the cluster but not its associated volume, so all data will remain intact. If you're using an external PostgreSQL database, this will not be affected.

    helm uninstall --namespace coder coder

    Make sure to check the namespace for items that are slow to delete. For example web-ingress can take some time to release the IP addresses; if you run the install command before this process completes, the install process will fail.

    Running uninstall removes the web-ingress service that owns the ingress controller's IP address. As such, the web-ingress service may have a new public IP address or hostname after you reinstall; if this is the case, update your DNS provider with your new IP and CNAME.

  3. Run the upgrade command with the new version number and Helm chart values file:

    helm upgrade --namespace coder --atomic \
    --wait --install --version 1.16.1 \
    coder coder/coder --values current-values.yaml

    The ingress may attach to a new public IP address; if this happens, you must update the host and Dev URL IP addresses with your DNS provider.
