Hi Brent & all,

I am sorry to forgot we still need dockerd to pull & push image to local registry, due to crictl doesn’t support push image [0].

So we cannot remove dockerd currently.

There is another containerd CLI “ctr”, which support pull & push image, but this tool is stated as “unsupported” [1].

So I prefer to keep use docker instead of ctr.

What is your suggestion?

Thanks.

Hi Brent,

[BR] What is the plan to remove dockerd ?

[Shuicheng] We need switch armada to run with containerd first, then we should be able to remove dockerd.

Task 37231 is created to track it under the same story[0].

Task 36981 is for switch armada to run with containerd.

I prefer to do both task in later stage.

Hi Frank & Brent & all,

I have updated my patches to remove the visible password for registry.

Please help review the update in ansible-playbooks/stx-puppet.

Here is the link for the patch list:

https://review.opendev.org/#/q/topic:kata+(status:open)

- Add a commit to make containerd the default CLI (and remove any docker code that is no longer needed)

[shuicheng] do you mean change the “/var/lib/docker” directory to “/var/lib/containerd” for both docker and containerd?

If the answer is yes, I prefer to do it later, after docker runtime is not used at all. Currently, armada is still using docker.

- Add a test case for local registry pull/push and authentication

[BR] What is the plan to remove dockerd ?

[Shuicheng] No plan yet. We need switch armada to run with containerd first, then we should be able to remove dockerd.

Task 37231 is created to track it under the same story[0].

Task 36981 is for switch armada to run with containerd.

[shuicheng] With the new patch, local registry still could be accessed both by Kubernetes and crictl.

For crictl, username/password need be provided in CLI, similar to “docker login” for docker CLI.

- Update code to ensure admin password is not visible

[shuicheng] Done.

Best Regards

Shuicheng
