An introduction to Clear Containers

Provided of course that you verify that the dockerfile do not suddenly start to do a curl | bash or this kind of stuff, as we tend to see on the docker registry and all across the place. Or pip install, etc.

And of course, provided the containers do not requires schema change or any kind of upgrade to the DB or any data store ( storage that you also likely need to handle, potentially with containers too, if possible, in a shared cluster way, which open all kind of fun problems ). That's problems that can be solved, but that's not as easy as people seems to imply.

( there is a few others issues to solve, like logging of containers, proper isolation, and the inherent dependencies on the kernel host which make practice != theory ). Secret distribution is also a interesting one, so how do you give your wordpress containers access to the mysql db somewhere in a clean way. ( again, doable and not a insanely hard issue, but requires a bit more than just the vanilla docker and a workflow that is well defined )
