How to uninstall Cert Manager

Uninstall Cert Manager from Automation Suite on EKS/AKS.

Prerequisites

• Kubectl CLI (kubectl) installed and configured.
• Appropriate permissions to delete resources in the target namespaces.

Information required

Before proceeding, you must gather the following information:

• UiPath namespace where cert-manager resources are being used.

Step-by-step uninstallation process

1. Delete the role bindings for cert-manager:

   # Verify if the role binding exists
   kubectl get rolebinding -n <uipath_namespace> | grep cert-manager
   
   # If it exists, delete it
   kubectl delete rolebinding <role-binding-name> -n <uipath_namespace>
   

2. Delete the cert-manager role:

   # Check if the role exists
   kubectl get role cert-manager -n <uipath_namespace> | grep cert-manager
   
   # If it exists, delete it
   kubectl delete role <cert-manamger-role> -n <uipath_namespace>
   

3. Clean up cert-manager resources in the namespace:

   # Delete all certificates
   kubectl delete certificates.cert-manager.io --all -n <uipath_namespace>
   
   # Delete all issuers
   kubectl delete issuers.cert-manager.io --all -n <uipath_namespace>
   
   # Delete all clusterissuers if you created any
   kubectl delete clusterissuers.cert-manager.io --all
   

4. Uninstall the cert-manager from cluster, delete the namespace or any residual certificate resources following steps 1, 2, and 3 for other namespaces. Also, cross verify if cert-manager is not used by any other component.
5. Verify remaining resources:

   # Check for any remaining cert-manager resources
   kubectl get all -n <uipath_namespace> | grep cert-manager
   kubectl get crd | grep cert-manager
   

Troubleshooting

If certain resources cannot be deleted:

• Ensure you have the necessary permissions.
• Check if the resources are being used by other applications.
• For resources that are stuck in Terminating state, you may need to remove finalizers.

Notes

• Only uninstall cert-manager if it is not being used by other applications in your cluster.
• If multiple applications depend on cert-manager, consider only removing the UiPath-specific resources.
• Replace <uipath_namespace> with your actual UiPath namespace.
