Shibboleth Idp3 as docker install on AWS

[Joseph Fischetti]

The way I've always handled it is that Tomcat points to a symlink for the current deployment.
Update the symlink and restart tomcat to switch deployments.
Rollback is just as simple.

It's also not immutable, so you can make configuration changes and utilize reloadable services on the fly.

Pushing from test to prod is as simple as tar -> scp -> untar -> symlink, which is all scripted.

Docker sounds like unnecessary overhead and complexity in this case.  Perhaps I'm missing something.
