This repo is obsolete. Tilt now maintains its own releaser image based on crazymax/osxcross.

This repo will be archived.

This repo contains a Dockerfile for building an image which is used to cross compile golang. It includes the MinGW compiler for windows, and an OSX SDK.

This image is available from https://hub.docker.com/r/dockercore/golang-cross and is used to build https://github.com/docker/cli.

1. Follow instructions here: https://github.com/tpoechtrager/osxcross#packaging-the-sdk for building an OSX SDK.

2. Copy the SDK under ./tarballs

3. Run docker build . to build the image
