_if they're already bought into the docker ecosystem_, this is true. if not, then they first have to go read up on docker first: figure out how to install it (OS-specific), enable the docker system services (i think systemd more or less standardizes this step), configure a user that has permissions to manage docker deployments (also frequently OS-specific), etc.

not saying docker is or isn't a worthy tradeoff between balancing distribution work between the code authors and the OS packagers and the users. just don't blind yourself that it is another thing that users have to learn before they can use your stuff.
