Build for ARM #35

Closed pathob closed 4 years ago

pathob commented 4 years ago

Hi, it would be very nice if you could also build your image for ARM. Thank you!

How to?

qoomon commented 4 years ago

like this https://www.docker.com/blog/getting-started-with-docker-for-arm-on-linux/?

I guess yes. The other approach might be to use an ARM container in travis for building, but I don't know how the tagging is done then in order to get a result like this: https://hub.docker.com/_/alpine?tab=tags

Unfortunately, I don't have experience with deploying Docker images or building for other architectures.

My current solution is to just build your image directly on ARM and that works fine. So at least I can confirm there are no architecture-specific changes necessary.

There are plenty of how-to's out there on building cross platform images, but here's how I do it to build python based images (FROM python) for my PC and Raspberry Pi in one go on my Windows 10 machine: You first need to enable docker buildx (experimental CLI). Check docker documentation on how to do that for your platform.

docker buildx create --name rpibuilder docker buildx use rpibuilder docker buildx inspect --bootstrap docker buildx build --platform linux/amd64,linux/arm/v7 -t \<imagename>:\<tag> \<path to dockerfile> --push docker buildx imagetools inspect \<imagename>:\<tag>

The last line is just to check if all went well.

Hope this helps!

Oh nice. Will try to add it to github action deploy pipeline.

enable experimental features is easy as export DOCKER_CLI_EXPERIMENTAL=enabled :-D

sdemets commented 4 years ago

If you have Docker Desktop, just go to settings -> command line and set "Enable experimental features" to on.
