Upgrading from v1.14 to v1.15

Before upgrading cert-manager from 1.14 to 1.15 please read the following important notes about breaking changes in 1.15:

GatewayAPI promotion to beta

GatewayAPI support has been promoted to beta, and thus the feature flag ExperimentalGatewayAPISupport is now enabled by default.

If you had previously enabled this feature flag you will now need to pass the flag --enable-gateway-api instead. This is because while the feature is now enabled by default, we still need to gate it behind a flag so cert-manager will not crash if the GatewayAPI CRDs are not installed.

Startupapicheck image change

As of this release the cert-manager ctl is no longer part of the main repo, it has been broken out into its own project. As such the startupapicheck job uses a new OCI image called startupapicheck. If you run in an environment in which images cannot be pulled, be sure to include the new image.

Next Steps

From here on you can follow the regular upgrade process.
