Dockerfile for Cross-compiling golang project with mitchellh/gox.

docker-library/golang (Docker official golang stack) also support image for cross-compile. With Dockerfile-gox, You can cross-compile your golang project parallelly. It's more fast when compiling for multiple platform.

tcnksm/gox image support below tags. Link is its Dockerfile.

• 1.2.2 (1.2.2/Dockerfile)
• 1.3 (1.3/Docekerfile)
• 1.3.1 (1.3.1/Dockerfile)
• 1.3.2 (1.3.2/Dockerfile)
  • 1.3.2-light (1.3.2/light/Dockerfile)
• 1.4 (1.4/Dockerfile)
• 1.4.1 (1.4.1/Dockerfile)
• 1.4.2 (1.4.2/Dockerfile)
  • 1.4.2-light (1.4.2/light/Dockerfile)

Tag is correspond to its golang version.

If you want to cross-compile with go v1.3.1:

$ docker run --rm -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp tcnksm/gox:1.3.1 

Or if you want to cross-compile with go v1.2:

$ docker run --rm -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp tcnksm/gox:1.2 

You can overwrite command. If you have Makefile with gox:

$ docker run --rm -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp tcnksm/gox:1.3.1 make 

Or if you want to build for 64-bit linux and change output to pkg directory with your favor name:

$ docker run --rm -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp tcnksm/gox:1.3.1 gox -osarch="linux/amd64" -output "pkg/{{.OS}}_{{.Arch}}/{{.Dir}}"

If you want to know gox arguments more, See documents in mitchellh/gox.

light tag provide light image. It only provides linux and darwin, windows build-chain. If you don't need other platform, use this image. You can use it in same way as ordinal one.

Here is image size comparison,
