Migrating Deprecated API Resources
The following cert-manager APIs were deprecated in cert-manager
These APIs are no longer served in cert-manager 1.6 and are fully removed in cert-manager 1.7. If you have a cert-manager installation that is using or has previously used these deprecated APIs you might need to upgrade your cert-manager custom resources and CRDs. This should be done before upgrading to cert-manager 1.6 or later.
An earlier version of this document listed a number of kubectl commands to run to migrate resources. These steps have now been encoded in
cmctl upgrade migrate-api-version command. If you have already run the kubectl commands, your resources should have been migrated and there should be no need to also run the
cmctl command. However, if you are not sure, you can still run the
cmctl command as well- it will be a no-op if no actions are needed.
Familiarize yourself with the official Kubernetes documentation on CRD versioning.
Make sure your cert-manager deployment is currently at version
Make sure that any cert-manager custom resource manifests that refer to the deprecated APIs are updated to use the
cert-manager.io/v1API and re-applied. You can use the cmctl convert commandto convert manifests.
