litaio / docker-lita Goto Github PK

lita.gemspec has this line spec.files = git ls-files.split($/). However, when I tried to run this from docker image litaio/lita it failed with the following error.

There was an error parsing `Gemfile`: There was a Errno::ENOENT while load
Oct 26 01:11:42 lita-test.c.lita-test.internal docker[1643]: No such file or directory - git from
Oct 26 01:11:42 lita-test.c.lita-test.internal docker[1643]: /app/lita.gemspec:16:in ``'
Oct 26 01:11:42 lita-test.c.lita-test.internal docker[1643]: . Bundler cannot continue.

My guess is because the corresponding docker image does not have git installed. Also as a work around I was able to substitute the problematic line with Dir.glob("{bin,lib}/**/*") + %w(LICENSE README.md) and that worked well for me.

Thanks!

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.

First off I'll admit I'm totally new to Docker, though I do have a good background in server admin. Lita has been a great way for me to learn, but I don't seem to be able to find a way around this.. I might just be missing something simple.

I've tried to use a git repo as the source for a gem, but since the docker container doesn't have git installed, bundler naturally fails.

gem "lita-against-humanity", :github => 'muyjohno/lita-against-humanity'

Is there any way to install git in the container before bundler is run, without manually recreating the docker file and making my changes? Would it be worth including git in your Dockerfile to cover this eventuality, and also issues like #1?
