14.2. Using Helm charts

Procedure

1. Add a chart repository by entering the following command:

   $ helm repo add redhat-cop https://redhat-cop.github.io/helm-charts

2. Enter the following command to update the information of available charts locally from the chart repository:

   $ helm repo update

3. Enter the following command to pull a chart from a repository:

   $ helm pull redhat-cop/etherpad --version=0.0.4 --untar

4. Enter the following command to package the chart into a chart archive:

   $ helm package ./etherpad

   Example output

   Successfully packaged chart and saved it to: /home/user/linux-amd64/etherpad-0.0.4.tgz

5. Log in to Quay.io using helm registry login:

   $ helm registry login quay.io

6. Push the chart to your repository using the helm push command:

   helm push etherpad-0.0.4.tgz oci://quay.io/<organization_name>/helm

   Example output:

   Pushed: quay370.apps.quayperf370.perfscale.devcluster.openshift.com/etherpad:0.0.4
   Digest: sha256:a6667ff2a0e2bd7aa4813db9ac854b5124ff1c458d170b70c2d2375325f2451b

7. Ensure that the push worked by deleting the local copy, and then pulling the chart from the repository:

   $ rm -rf etherpad-0.0.4.tgz

   $ helm pull oci://quay.io/<organization_name>/helm/etherpad --version 0.0.4

   Example output:

   Pulled: quay370.apps.quayperf370.perfscale.devcluster.openshift.com/etherpad:0.0.4
   Digest: sha256:4f627399685880daf30cf77b6026dc129034d68c7676c7e07020b70cf7130902
