Building from Source for Alpine Linux
Since many people are using Alpine Linux as their base images for Docker there's support to build Alpine package also. Naturally by using Docker itself. :)
$ docker build -t confd_builder -f Dockerfile.build.alpine . $ docker run -ti --rm -v $(pwd):/app confd_builder ./build
The above docker commands will produce binary in the local bin directory.
Get up and running with the Quick Start Guide.
