If they're running ubuntu 12.04 LTS they can keep the 3.2 kernel until late 2017. That's 2 more years. And they wrote "did not", so it was likely the situation months ago, not yesterday.

It depends on the amount of stuff they deploy. If they handle everything using Ansible (and from the list it looks like they do), then it's months of work to migrate to something else. They may need the right users / logging / secret management in the app itself, not outside of it.

It's not. It would be months of work if they wanted to convert all their Ansible code to Docker, but that's by no means required.

Docker and Ansible can easily coexist peacefully.

They can. But depending on how you used Ansible before, it may mean a heavy rewrite of your deployment strategy. I'm not saying it will always take that long. But depending on your app, the requirements may be very complex and not fit into the docker idea.

(it always means some extra work for security updates though - now you're updating both the host and images)

    sudo apt-get install linux-generic-lts-quantal

Easy to upgrade.

If you can, it's easy. I wish everyone to work in environments where it's that simple ;)

Kernel interface change is low on purpose. Test it first with additional vms before throwing up your hands and exclaiming it can't be done, you might be surprised.
