I've put up a
that builds the Pharo
pharo.cog.spur.minheadless VM on Alpine Linux
within Docker. This allows one to build said VM without having to first
create an Alpine Linux installation such as through VirtualBox.
This is a multi-stage Dockerfile. The Pharo VM is built in an Alpine Linux 'build' container. Then the VM files are copied into a fresh Alpine Linux Docker image. The resulting Pharo VM Docker image is ~14 MB.
The output Docker image contains the Pharo VM only and is not runnable by itself. It is intended to be used as a base to build your own Docker image containing your application-specific Pharo image.
Tested on Ubuntu 18.04 and MacOS Mojave.
Edit: Changes to OpenSmalltalk VM source tree for building on Alpine Linux
are in the
pierce_alpine branch of my fork.
