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 mickaelmenu/zk-xcompile:linux-arm64 /bin/bash -c './go build'

Releasing changes

docker build -t mickaelmenu/zk-xcompile:linux-amd64 ./linux-amd64
docker push mickaelmenu/zk-xcompile:linux-amd64

docker build -t mickaelmenu/zk-xcompile:linux-arm64 ./linux-arm64
docker push mickaelmenu/zk-xcompile:linux-arm64

docker build -t mickaelmenu/zk-xcompile:linux-i386 ./linux-i386
docker push mickaelmenu/zk-xcompile:linux-i386
