Tab Completion

How can I enable tab completion ? I tried installing bash-completion using apt, but, it didn't work.

Once it's installed, you have to restart your shell session (or start a new one). Your best bet is likely going to be to write a simple Dockerfile which installs it, and then use that instead of debian:... directly (if you need this on the base image itself).

Alternatively, I think there's some file it installs that can be sourced from the current session, but I don't recall the exact details offhand.

Adding RUN apt-get install -y bash-completion to Dockerfile did the trick.
Would love to see the tab-completion enabled by default in the base image, though.

The base image is kept intentionally slim -- we use --variant=minbase on our invocation of debootstrap so that we have the smallest possible set of packages that we can still call "Debian".
