Docker: Running nano in docker container

I open an interactive shell into a docker container like so

sudo docker exec -t -i {container_name} bash

So far so good but trying to run nano results in:

Error opening terminal: unknown.

I think this can be related with Docker Issue #9299.

There are some workarounds commented in that issue:

• Run the container allocating a pseudo-TTY (option -t).
• Export environment variable $TERM=xterm in the container's process run in exec (i.e.: export TERM=xterm)
