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

Classic infrastructure

The strongSwan IPSec VPN addon is deprecated, and will be unsupported on December 20, 2025. See Classic VPN connectivity for other options

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
