neroinc/ubuntu-golang-crosscompile repository overview

⁠ubuntu-golang-crosscompile

Go 1.4 runtime based on ubuntu:trusty, set up for cross compilation to Linux (i386, AMD64, ARM) and Windows (i386, AMD64). Note that ubuntu:utopic contains a change to tzdata which breaks Go compilation⁠ for now.

Go is installed to /goroot/bin, application source code goes into /gopath/src/.

Build the image:

docker build --rm -t neroinc/ubuntu-golang-crosscompile .`

Start a container with an interactive shell and port 8080 published:

docker run -it -p 8080:8080 neroinc/ubuntu-golang-crosscompile /bin/bash`

To mount your local work directory (e.g. using Boot2docker⁠) into a new docker container, run:

docker run -it -p 8080:8080 -v /Users/<workspace path>:/gopath/src/<your domain> neroinc/ubuntu-golang-crosscompile /bin/bash`

⁠Examples

Build your application (thanks to mazzolino⁠ for the tip):

docker run -it --rm -v $GOPATH:/gopath -w /gopath/src/example.com/my/example -e GOOS=linux -e GOARCH=arm -e GOARM=7 neroinc/ubuntu-golang-crosscompile go build -v -o example-armv7`

Or with CGO⁠ enabled:

docker run -it --rm -v $GOPATH:/gopath -w /gopath/src/example.com/my/example -e CC=arm-linux-gnueabihf-gcc-4.7 -e GOOS=linux -e GOARCH=arm -e GOARM=7 -e CGO_ENABLED=1 neroinc/ubuntu-golang-crosscompile go build -v -o example-armv7

Now you should have a new executable called example-armv7 inside your project directory.

This should work with boot2docker as well if you have $GOPATH inside your /Users subdirectory.
