Misc Dockerfiles

A repo containing misc Dockerfiles.

Some of these are available via Dockerhub.

Multi-arch build instructions

Based on John Rofrano's instructions:

Initialize builder

If you don't have a builder you must first create one:

% export DOCKER_BUILDKIT=1
% docker buildx create --use --name=qemu
qemu
% docker buildx inspect --bootstrap

Building a multi-arch image

docker buildx build --tag {account}/{name:tag} --platform=linux/amd64,linux/arm64 --push .

This will use QEMU to build a multi-platform image and push it to docker hub.
