- What I did
Previously, when user run vtysh from the base system and disconnected from the terminal, the pty where vtysh was running in the container was left used. It is because of SIGHUP which is not passed inside of the docker. See moby/moby#28872 This patch don't create new pty to run vtysh in the container.
- How I did it
I changed command line option for docker exec.
- How to verify it
Build DUT and check
Or change /usr/bin/vtysh on DUT, run vtysh, disconnect from the terminal, connect back and check vtysh in the list of processes.
