I open an interactive shell into a docker container like so <pre class="prettyprint"><code>sudo docker exec -t -i {container_name} bash </code></pre> So far so good but trying to run <code>nano</code> results in: <blockquote> Error opening terminal: unknown. </blockquote>

I think this can be related with Docker Issue #9299. There are some workarounds commented in that issue: <ul> <li>Run the container allocating a pseudo-TTY (option <code>-t</code>).</li> <li>Export environment variable $TERM=xterm in the container's process run in exec (i.e.: <code>export TERM=xterm</code>)</li> </ul>

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)
