Cross-compiling zk with Docker

Largely inspired by dh1tw and remoteAudio-xcompile.

How to invoke?

You can compile the zk source code directly from the source code directory. As example, for compiling the binary for linux/arm64 you have to execute the following command:

docker run --rm -v "$PWD":/usr/src/zk -w /usr/src/zk ghcr.io/zk-org/zk-xcompile:linux-arm64 /bin/bash -c 'make'

This call is already set in zk Makefile, e.g. make dist-linux-amd64.

More detail is documented here on Golang's docker hub.

The images are hosted with ghcr within zk-org.

Releasing changes

Clone this repo, make necessary changes, submit a PR. After PR is confirmed, proceed with building and pushing.

Building

docker buildx build -t ghcr.io/zk-org/zk-xcompile:linux-amd64 ./linux-amd64
docker push ghcr.io/zk-org/zk-xcompile:linux-amd64

or via the build script

./build # builds all images
./build ./linux-amd64 ./linux-arm64 # build desired images only

Pushing

Logout of docker if you're currently logged in: docker logout or via Docker Desktop.

Then login to ghcr.io with your personal access token. Only members of zk-org can push. Docs are here.

For example:

echo $ZK-TOKEN | docker login ghcr.io -u USERNAME --password-stdin

Then you can push to our container registry.

docker push ghcr.io/zk-org/zk-xcompile:linux-amd64

or via the push script

./push # pushes all images to zk-org ghcr
./push ./linux-amd64 ./alpine-amd64 # push desired images only
