Controller does not delete listeners having specific tag (e.g. indicating listeners are externally managed)

[paulzhang97]

Issue

The controller removes listeners not recognized by itself. In some deployments, listeners are created outside of the controller and managed externally. We need a way to tell the controller not to delete such listeners during reconciliation.

Related issue

Description

Listener synthesizer get the env variable PREVENT_DELETION_TAG_NAME specifying the tag name for not deleting listeners. It does not delete listeners tagged with the one set by PREVENT_DELETION_TAG_NAME.

Hi @paulzhang97. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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.

I have the same issue as the user above. ALB removes listeners not recognized by itself. This makes it impossible to share aws alb controller with a non k8's service or ec2 instance. I am doing path based routing and I have resource that uses to much memory and cpu and I do not want to migrate it to k8s. I am stuck between a rock and hard place because resources is used in so many parts they cannot change it. Can this be escalated!!!! Please!!!!!

[paulzhang97]

@modevops I implemented it at the forked repo. Check it out to see whether it meets your needs.
