Running Docker on Armv5 (pogoplug v4)

[earlg]

I installed docker on a pogoplug v4 running alarm and it crashes whenever I try to start it. (using systemctl or as 'docker -d')
I have updated to the latest kernel by installing linux-kirkwood( thanks WarheadSE for the tip).
After searching around, it seems that the developers behind docker do not officially support architecture other than arm64:
https://github.com/docker/docker/issues/3479
I see this thread viewtopic.php?f=60&t=7232 but it does not have a clear conclusion.
Has anyone been successfully running docker on an arm device? If so what device are you using?

[moonman]

Just pointimg out they only support amd64 which is x86_64 and NOT arm64.

[earlg]

I see. Thanks for the clarification moonman.

This is changing as I convince them to make it work We do however have a few bugs I am still working with them on fixing. Like this sqlite problem.

[mattwallington]

earlg, are you still working on this? I need to do the same thing and have been working on getting it to work on an Armv5 device as well. Want to collaborate?

[mattwallington]

Warhead, Do you know if there are any plans to get it to work properly on ARMv5? Also, are you abandoning Docker development in favor of Rocket now?

[WarheadsSE]

I continue to work with Docker for the time being, I see no reason to ""jump ship"" since they are separate projects, I don't have to ""leave one"". I simply have not started packaging Rocket yet.

Last I checked, they were debating on removing sqlite altogether, which would have solved the issue. I will have to revisit.

Hi,

I'm also trying to make Docker work on Armv5, on a Sheevaplug this time.

There many reports of people making Docker work on Rhasperry Pi (Armv7), so why not on Armv5 ?

But I think I have a problem at an earlier step than earlg. (By the way, pacman -Sy docker does not install the bridge-utils packet as a dependency). Docker seems not to be able to create a network interface.

')

lsmod gives me nothing, but that may be expected, right ?

Any idea ?

The RPi is ARMv6 with hardfloat vfp. It is not an ARMv7.

taophp, I had that same problem and it turned out to be that I didn't have the proper dependencies built into the kernel. I don't remember all the dependencies right now but you need to enable iptables and bridging. You also need to install the bridge_utils package.

I wish I could have documented exactly which features I had to build into the kernel but I'll be revisiting this shortly after the holidays and can publish a list when I get myself back to where I was a couple of weeks ago.
