Hi @stephensarabiasurion. Thanks for your PR.

I'm waiting for a aws-controllers-k8s member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Hi @stephensarabiasurion thanks so much for the PR!

Looks like some of the hooks aren't wired up properly. code-gen should handle that for you.

Did you hand-edit files for this PR? ACK leverages code generation, so you should not need to edit files like sdk.go, types.go, etc

We have contributor docs on the old docset, we prob need to update this.
https://aws-controllers-k8s.github.io/community/docs/contributor-docs/overview/

Can you try a reset and:

1. Update your ignores in generator.yaml (don't worry about apis/v1alpha1/generator.yaml, it gets built)
2. add your AuthenticationMode handling to pkg/resource/user/hooks.go
3. Rebuild — SERVICE=elasticache make -C code-generator build-controller

That should create the code, wire things up, and create your kustomize/helm artifacts for you. If all goes well, force push and we'll see where that lands? Holler if any of this doesn't make sense, thanks!
