Docker on Odroid C2?

[ivanthesquid]

Hey all,

I'd really like to run Docker containers on my C2s running alarm. When I use systemctl to start docker, the command hangs at the command prompt. I'll ctrl-c to get the prompt back.

doing 'sudo systemctl status docker', I get:

$this->bbcode_second_pass_code('', '

')

With dmesg, I see this sort of record which seems to reference containerd failing:

Any thoughts/clues/hopes about getting Docker containers running in alarm on Odroid C2?

Thanks,

You are getting this error because of the version of containerd running with docker 1.11.*.
See here: https://github.com/docker/docker/issues/22950

I have managed to get Docker to boot using the master branch.

You can find relevant PKGBUILD files in the following repo:
https://github.com/archlinuxarm/PKGBUILDs/tree/master/community

By modifying them you can build docker and containerd from master.

Despite my success in building docker and starting the daemon, I have not been able to start a container yet as I am getting consistently the following error: "docker: Error response from daemon: shim error: open pid: no such file or directory".

For more info see here: https://github.com/docker/docker/issues/23467

Using yaourt you can install the latest dev branch of Docker, containerd and runc which results in a functional installation of docker.

Thanks for that tip, crvgkb. I was able to get docker running on my C2 after getting yaourt up-and-running.
