How do you change default detach key sequence in docker?

问题

Docker container's detach key sequence by default is control+q or control+p. There is an option to set key sequence when starting a container using --detach-keys "<sequence>" but I am looking for a permanent change.

Is there a way to change this key sequence to something else?

回答1:

Per user, you can configure this in the $HOME/.docker/config.json file. Add a json entry similar to:

{
  "auths": { ... },
  "detachKeys": "ctrl-x,x"
}

The "auths" line is just giving a relative location in the json, ignore this if you don't have an existing logins stored in this file. See this documentation for more details.
