⁠Manifest List

Create a multi-architecture manifest list.

Background

A single tag in a Docker registry (e.g. docker.io/ubuntu:bionic or docker.io/fnndsc/ubuntu-python3:latest) can refer to multiple images for different architectures. When a local docker engine executes docker pull or FROM in a Dockerfile, the correct image that matches the host's native architecture is used.

Images that use FROM fnndsc/ubuntu-python3:latest in their Dockerfile (most fnndsc/pl-* plugins for ChRIS) can also be built for multiple architectures. You can simply build the same Dockerfile on different hosts without modification, or follow the steps below⁠ to build cross-platform.

Note that Dockerhub cannot do autobuilds for non-x86_64 images.⁠. Autobuilds from Dockerhub (again, most fnndsc/pl-*) are only for x86_64. fnndsc/ubuntu-python3 is built using Travis⁠, which is a bit less convenient.

⁠Build

Linux x86_64 (check with uname -sm) can use QEMU emulation to do cross-platform builds for foreign architectures.

First, make sure you have Docker CLI experimetnal features enabled. https://github.com/docker/buildx#docker-ce⁠

docker run --rm --privileged aptman/qus -s -- -p ppc64le
docker buildx create --name moc_builder --use
docker buildx build -t fnndsc/ubuntu-python3 --platform linux/amd64,linux/ppc64le .
# clean up
docker buildx rm
docker run --rm --privileged aptman/qus -- -r

⁠Travis Automatic Builds

Travis Badge

Travis automatically builds and pushes master⁠ branch to Dockerhub⁠ as fnndsc/ubuntu-python3:latest. This manifest list will contain images for x86_64 and PowerPC.

If the latest commit is tagged (git tag <tag_name>), then the automatic build will also have that tag in addition (fnndsc/ubuntu-python3:latest and fnndsc/ubuntu-python3:<tag_name>). In that case we should update https://github.com/FNNDSC/cookiecutter-chrisapp⁠ Dockerfile to use the new fnndsc/ubuntu-python3:<tag_name>.
