Fix ciliums hubble relay configuration #9876

prashantchitta · 2023-03-09T19:33:47Z

This fixes the ContainerCreating status that appears because hubble relay has changed upstream. These changes are based on upstream cilium helm.

Hubble relay now uses k8s service to discover peers rather than unix socket. A new k8s service for peers and metrics are introduced

You will be prompted by a bot to use commands during the review process. Do not be afraid to follow the prompts! It is okay to experiment. Here is the bot commands documentation.

You can also check if kubernetes-sigs/kubespray has its own contribution guidelines.

You may want to refer to our testing guide if you run into trouble with your tests not passing.

If you are having difficulty getting your pull request seen, please follow the recommended escalation practices.

Hi @prashantchitta. 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Why do you remove TLS feature?

It is generated by CronJob, right?

I created the PR to fix that
#9880

@prashantchitta Could you take a look at #9880 of @utam0k ?
If that is good, we can keep a swtich of disable-server-tls based on the pull request.

@oomichi @utam0k can you take a look now?

utam0k

Looks good to me
