I expect that if you go to something like Docker's official container registry you will find vast numbers of copyright violations of one form or another. Violations of GNU userland, kernels, apache licensing violations, etc?

If somebody pulls in a Ubuntu container their app is it Canonical's job to provide the source code or is the person redistributing the resulting software binaries?

If you have Joe Blow posting a container for his blogging software it is technically going to be a violation if he doesn't provide written notice and provide all the source code along with the container. Lots of the times the only reference a container has is some github page and even then a lot of those projects never last very long.

With the commodization of operating systems that things like containers represent you see the costs of copyright compliance for various FLOSS items soring in comparison to the costs of actually building and distributing the software. Luckily most people don't seem to care because access to every bit of source code is not really a high priority and if it was they know where to easily get it. However there could be some pretty serious problems down the road if some critical copyright holder decides to try to force everybody to take his copyright very seriously.
