Build Status

golang-crossbuild is a set of Docker images containing the requisite cross-compilers for cross compiling Go applications. The cross-compilers are needed when the application uses cgo.

The base image used is Debian 9 (stretch) unless otherwise specified.

Usage Example

docker run -it --rm \
  -v $GOPATH/src/github.com/user/go-project:/go/src/github.com/user/go-project \
  -w /go/src/github.com/user/go-project \
  -e CGO_ENABLED=1 \
  docker.elastic.co/beats-dev/golang-crossbuild:1.10.8-arm \
  --build-cmd "make build" \
  -p "linux/armv7"

This will execute your projects make build target. While executing the build command the following variables with be added to the environment: GOOS, GOARCH, GOARM, PLATFORM_ID, CC, and CXX.

Releasing images for a new Go version

  1. Update the Docker tag in Makefile.common and/or Makefile.common and/or Makefile.common.
  2. Update the Go version and SHA256 in the Dockerfile(s). The SHA256 must be obtained from https://golang.org/dl/.
  3. Update the versions listed in this README.md.
  4. Commit the changes. git add -u && git commit -m 'Update to Go 1.x.y'.
  5. Create a Pull Request with the description 'Update to Go 1.x.y'.
  6. When merging the PR then the automation will release those docker images.

Manual steps

This is not required unless the CI service is down.

  1. Build the images from the project's root with make.
  2. Get a logon token for the container registry by visiting https://docker.elastic.co:7000.
  3. Publish the images with make push.
