When using the Execute Shell option within the UI it times out. I have a couple recommendations
1)Do not kill shell if active (Shell scripts, etc)
2)Improve Shell view to increase the console size (maybe full screen)
3)Ability to log into host
There is no built-in timeout. If you are using a proxy, load balancer, or SSL termination, that device needs a longer timeout set.
Resize requires somewhat complicated communication to tell docker on the host to resize the tty and we just haven’t gotten to it.
