First, use this command ( b1e3c456f07f is the container id ):

docker inspect --format='{{.LogPath}}' b1e3c456f07f

The result will be something like this:

/var/lib/docker/containers/b1e3c456f07f2cb3ae79381ada33a034041a10f65174f52bc1792110b36fb767/b1e3c456f07f2cb3ae79381ada33a034041a10f65174f52bc1792110b36fb767-json.log

Second, use this command ( you can use vim if you like ):

nano /var/lib/docker/containers/b1e3c456f07f2cb3ae79381ada33a034041a10f65174f52bc1792110b36fb767/b1e3c456f07f2cb3ae79381ada33a034041a10f65174f52bc1792110b36fb767-json.log
