dind for aarch64?

[vielmetti]

I'm looking at running docker-in-docker for aarch64 (ARMv8). I don't see an officially supported version in the usual place (https://hub.docker.com/u/aarch64/docker/ is where I'd expect it). Suggestions and what to do next welcomed.

👍 and for armhf.

@tianon is this within the realms of possibility?

We want to have more architectures, but we only grab the binaries as released by docker, so until they release and support more we would have to recreate the build process. 😢 There are armel and i386 tar bundles on get.docker.com, but I am not sure if the armel binaries work and the i366 tar only contains the client binary.

On a side note, we are working to integrate multiple architectures more directly into the official-images and hope to use manifest lists (or whatever the new name is) so that docker pull docker:dind will pull the correct architecture. For more information see docker-library/official-images#2289.

For the short term, to get more architectures, we'll continue to use tianon's groovy repo as we list on the official images repo.

Thanks @yosifkit . I have been coordinating with Olivier and Andrew to get a Jenkins server running on a 96-core Packet 2A ARMv8 machine for Docker use, if you or @tianon are not in touch with them yet about that resource it could help things along to make that connection.

Bumping this as still of interest @yosifkit

Docker has deprecated https://get.docker.com builds in favor of the new https://download.docker.com/linux/static/, which is what we now consume. Once Docker Inc officially supports ARMv8 there, we will consume those official releases here. 👍

Hi when did get.docker.com get deprecated? (news to me) There is only one architecture at the new site url though.. so what do we do for the RPi etc tutorials?

[tianon]

I saw it in a Docker release announce mailing list email, but I don't know whether it's public anywhere (as I noted over on #54 (comment)).

Important: The Docker CE Edge versions 17.05 will be the last release published on https://get.docker.com, https://apt.dockerproject.org, and https://yum.dockerproject.org. Starting with the Docker CE Edge 17.06 release, all new packages will only be published on https://download.docker.com, and on Docker Store.

I'm not sure what the communication plans are for that, but I'd recommend contacting Docker, Inc for further guidance. I think the new APT repos still have armhf (it's just the static binaries getting the shaft), but I haven't confirmed that for sure. Sorry! 😕 😞

@alexellis the intended purpose of the get.docker.com script was for convenience to install the legacy docker-engine packages, but kinda grew in scope to other installation options. Now that we've finished the last release of docker-engine 17.05.0 we're looking at a way to provide an alternative convenience install script to help install just the docker-ce packages from download.docker.com for future versions. It's on our radar...intended for 17.06.0 release. In the meantime (you probably already know), install instructions: https://docs.docker.com/engine/installation/

Just to add to @andrewhsu - we'll probably also host he the refactored install-helper script that we're building for download.docker.com on get.docker.com for backwards compatibility. As mentioned, this script will only install docker-ce packages.
