Hi @haad. Thanks for your PR.

I'm waiting for a kubernetes 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 @haad. Sorry for the delay in answering. We had some discussions about this topic at our weekly meeting and some concerns were raised about adding passwords directly into kOps config. There was no consensus on how to approach this last week, but it's still on our list of priorities.

One question came up about the use of Docker secrets managed by kOps which are directly used by k8s even with containerd. Did you try to see if those work somehow for the mirrors too?.

[haad]

I understand, but We are not forcing our users to include those passwords there. Plus you have an option to use a token, too. Right no every Kops users has to override this config as a whole which isn't a good thing. It complicates workflow for them as they have to check if we have not changed default configuration(containerd/config.toml) before each upgrade.

We should be able to add some cloud based password insertion scheme (Use aws system parameters as passwords), but I would add/implment that functionality as a separate PR.

[blakebarnett]

Shouldn't this be implemented similarly to the host-level docker auth (as a secret)? We could maybe abstract it to be a generic "registry auth" secret, and have it apply to both...

for reference: #3087

[olemarkus]

That would be my preferred way of implementing this
