Working with VM images was PITA, I don't know if anything changed. Having recipe (Dockerfile) and required files in VCS is useful as reference even when setting up bare metal machines. So Docker (and Puppet/Ansible) might have bigger impact on work organisation than on anything else.

You still have the Dockerfile and the required files in a VCS, but now what you have running is a full VM instead of a somewhat isolated process sharing kernel with other containers.

So far so good, for individual/standalone containers. But if you need thightly integrated containers (sharing networks, volumes, ports and so on) things may be a bit more complicated. And not sure about Kubernetes. YMMV

It's not such a PITA anymore. Most distros have automated build systems to create VM images from a config file. For example, we use FAI + Ansible to entirely automate the creation of a Debian AMIs for AWS, deployment, and provisioning.
