docker-cross-compiler-go

WARNING: Ths container has been deprecated in favor of a single all-purpose Drobo cross-compiler environment here: Github or Docker Hub.

Pull the container

This container is available from Docker Hub.

docker pull droboports/go-compiler

Build the container

docker build --tag="droboports/go-compiler" https://github.com/droboports/docker-cross-compiler-go.git

Start a temporary interactive container

docker run --rm -t -i droboports/go-compiler

Build something using a temporary interactive container

From the container prompt:

cd ~/build
export GOPATH=/mnt/DroboFS/Shares/DroboApps/hello-world
cat > hello-world.go << EOF
package main
import "fmt"
func main() {
  fmt.Println("hello world")
}
EOF
go build -o hello-world hello-world.go

This is the resulting hello-world:

$ file hello-world
hello-world: ELF 32-bit LSB  executable, ARM, EABI5 version 1 (SYSV), statically linked, not stripped

Using the container's build command

This container provides a special build command to build projects in git repositories.

The syntax is build project-name or build url.git, where project-name is the name of the DroboPorts project, and url.git is the URL of a git repository.

For DroboPorts projects, the name is the last component of the GitHub URL. For example, to build the project hosted by the repository https://github.com/droboports/busybox, use the name busybox.

To use the build command, first create a folder to host the resulting packages:

mkdir -p ~/dist
chmod a+rw ~/dist

Then start the container using the special build syntax:

docker run --rm --volume ~/dist:/dist droboports/go-compiler build project-name

Once the build is done, ~/dist will contain project-name.tgz. If no tgz was produced, the docker container will start a bash shell.
