Why can't I install a new strongSwan Helm chart release?

Classic infrastructure

You modify your strongSwan Helm chart and try to install your new release by running helm install vpn iks-charts/strongswan -f config.yaml. However, you see the following error:

Error: release vpn failed: deployments.extensions "vpn-strongswan" already exists

This error indicates that the previous release of the strongSwan chart was not completely uninstalled.

Delete and re-install the Helm chart.

1. Delete the previous chart release.

   helm uninstall vpn -n <project>
   

2. Delete the deployment for the previous release. Deletion of the deployment and associated pod takes up to 1 minute.

   oc delete deploy vpn-strongswan
   

3. Verify that the deployment has been deleted. The deployment vpn-strongswan does not appear in the list.

   oc get deployments
   

4. Re-install the updated strongSwan Helm chart with a new release name.

   helm install vpn iks-charts/strongswan -f config.yaml
