Updates to use more recent versions of build tools, the old versions can no longer build canvas-lms. Also fixes for docker image bloat/slowdown caused by using chown -R

Thanks for the PR. I wasn't paying attention during the build but it finished OK. When I run the resulting image I get an error I don't know enough about rails to interpret.

I think I got that as well but that it resolved itself after restarting the container. I'm not sure if there's a better way to fix it.

whoa that actually worked for me too. weird... i mean, working in some capacity is better than not working at all, so I'll probably mrege this. Would you mind adding a big, attention-getting note to the readme that mentions the need for this container restart?

I've added a healthcheck that notices when the landing page is returning a 500 error and restarts the canvas_web service in supervisord

Ran into a build error during dbinit due to missing timestamps, but worked like a charm after the following change:
