I'm on Ubuntu 18.04, starting an interactive docker terminal with:



docker run --rm -it <image>


After typing a few commands, I type Ctrl+P to see the last command in history. The prompt remains blank, but typing Ctrl+P again shows the second to last command. Ctrl+N then works as expected.



The same issue occurs on all my machines. It also seems to be an issue specific to Ctrl+P because those keys don't work in vim in docker either.



Oddly enough, using the up arrow from the beginning also does as expected. Why is the prompt blank with Ctrl+P?

          See the SO question How do you attach and detach from Docker's process? for the root cause. I can see how it'd be useful to have keys for this in docker, but it's surprising the default chord starts with such a common key combination.



          See Use the Docker command line | Docker Documentation for a solution. To summarize that page, create a .docker/config.json file in your home directory and use the same default suggested in the docker documentation:




          "detachKeys": "ctrl-e,e"
