May i replace default containerd with firecracker-containerd???

[Nurmukhamed]

Hello everyone.
I learn how to use firecracker. I wrote article about installing firecracker on CentOS 7, russian language.

Now i want to use docker that run containers in firecracker. Is there way to use native docker command to run containers in firecracker???

And

As i understood, firecracker-containerd and containerd has same functions. May i replace containerd with firecracker-containerd?? or change systemd docker.service to use firecracker-containerd.sock???

Sorry for bad english.

It may not work as a drop-in replacement.

• firecracker-containerd only supports devmapper
• firecracker-containerd launches a completely separate micro VM. Some features such volumes would not work.

P.S. Thanks for the blog post!

Hello. Thank you for response..

May i send pull-request with redhat specific files - specs???

For Firecracker itself or firecracker-containerd? For the former, it would be better to ask on firecracker's repository. For the latter, we are currently not having versioned releases. Would it be a blocker? I don't know much about packaging.

@kzys what is missing to run frecracker-containerd as a replacement of containerd in a kubernetes cluster?

[kzys]

@mazzy89 This is still unknown for us. We should build firecracker-containerd with CRI and run CRI's conformance tests to see what's missing. I was working on that before (#255) but couldn't finish.

@kzys
Is there has any official Slack channel to discuss this or any other topics?
I want to hear more newest progress about that.
