Base image based on ubuntu that contains basic builds tools and a spawn helper
docker pull mafintosh/base
In addition to basic build tools (build-essential, git etc) this contains a program
called spawn written in c for minimum memory footprint.
The only thing this program does is spawn another a child process with the arguments you pass to it. This way you avoid being PID=1 (which otherwise might result in some issues)
Just use the FROM stanza and add spawn to your ENTRYPOINT if you want to use thats
FROM mafintosh/base
ENTRYPOINT ["spawn", "my-app"]
