Instructions on upgrading

For every Helm Chart upgrade, the steps in the following guide need to be executed.

Upgrading the Helm Chart

Additionally, the following are the steps to upgrade from v0.9.9 to v0.9.10.

Steps before upgrading

New Grafana version

In this release we updated the Grafana version from 8.5.9 to 9.3.1. Check the release notes for further information about possible breaking changes that could affect you.

Grafana

If you don’t have any custom Grafana plugins installed, skip to step 4.

1. From Grafana, navigate to the Plugins section inside the Configuration tab

2. Make sure that only the installed plugins are selected

   

3. Write down all the plugins that you manually installed. You can recognize them by not having the Core tag. Also, the following ones already come with the UMH stack, thereby you don’t need to note them.

   • ACE.SVG by Andrew Rodgers
   • Button Panel by UMH Systems Gmbh
   • Button Panel by CloudSpout LLC
   • Discrete by Natel Energy
   • Dynamic Text by Marcus Olsson
   • FlowCharting by agent
   • Pareto Chart by isaozler
   • Pie Chart (old) by Grafana Labs
   • Timepicker Buttons Panel by williamvenner
   • UMH Datasource by UMH Systems Gmbh
   • Untimely by factry
   • Worldmap Panel by Grafana Labs

   

4. From Lens, under Deployments, remove the Grafana deployment. This will cause a brief downtime, but no data will be lost.

5. Now you can proceed with the other steps on this guide before upgrading.

Updating the Grafana init container

1. Search for “grafana-plugin-extractor”

       name: init-umh-datasource
       volumeMounts:
       - mountPath: /var/lib/grafana
         name: storage
   

3. With

   extraInitContainers:
       - image: unitedmanufacturinghub/grafana-umh:1.1.2
         name: init-plugins
         imagePullPolicy: IfNotPresent
         command: ['sh', '-c', 'cp -r /plugins /var/lib/grafana/']
         volumeMounts:
           - name: storage
             mountPath: /var/lib/grafana
