Removing ANSI Colours from Log Output

Despite using the --no-color switch for docker logs, I still get colour output. This is frustrating as I just want to throw the output into a file for analysis and the colour codes just add interference, eg.

$ docker-compose logs --no-color keycloak > output.log

Pipe the output through sed like this and get clean output.

docker-compose logs --no-color keycloak | sed -r "s/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[m|K]//g" > output.log
