Publish to Docker Hub

Note: This process requires Docker >=17.05 as it uses a multistage build.

You can publish frugalos images to Docker Hub by the following commands:

// Clone the repository and move to the target directory.
$ git clone git@github.com:frugalos/frugalos.git
$ cd frugalos/docker/hub/

// Build a frugalos image of the specified version and publish it to Docker Hub.
$ ./publish.sh 0.9.0

After publishing, you can execute the frugalos image as follows:

$ docker run -it --rm frugalos/frugalos:0.9.0
