Upgrade the Presslabs Dashboard

WARNING

If done correctly, there shouldn’t be any downtime for your sites. If we cannot avoid some downtime for a version, it will be no more than a couple of minutes, or we’ll explicitly mention it here.

Upgrade the Presslabs Dashboard

To upgrade the Presslabs Dashboard, you need to install a new release and then, after it is ready, remove the old release.

Install a new release

To install a new release, follow the steps from how to install the Dashboard , taking into consideration:

• install it into the same namespace where you have the current Dashboard version
• for the new application use a different name from the current application
• create a new Presslabs Dashboard Service Account; reusing the old one won’t work, because it will get deleted when uninstalling the old Dashboard version

NOTE

All Dashboard features are available only for Kubernetes 1.17 and Kubernetes 1.18, so make sure to have a Static version for your cluster with these versions. If not, upgrade your cluster . Dashboard 1.7 was tested on versions 1.18.15-gke.1501 and 1.17.17-gke.1101.

Remove the old release

After you install the new release and wait for it to be ready, you can remove the old Dashboard release.

To delete the old Dashboard version, go to Kubernetes Engine -> Applications and delete it from here. For example, if you upgrade from version 1.6 to version 1.7, you have to delete the 1.6 version:

Upgrade the Kubernetes cluster

All Dashboard features are available for Kubernetes 1.17 and Kubernetes 1.18, so make sure to have a Static version for your cluster with these versions. If not, you can upgrade your Kubernetes cluster and nodes versions by following the Google Kubernetes Engine documentation .

NOTE

Be aware that the nodes shouldn’t be on auto-upgrade, as not all Dashboard versions work with the latest cluster versions.
