Update stop-containers-during-backup.md

[jastlw]

Read-only for /var/run/docker.sock:/var/run/docker.sock is wrong. Otherwise, a stop of different containers may not be possible.

Here is it all right: https://offen.github.io/docker-volume-backup/recipes/#using-mariadb-dumpmysqldump-to-prepare-the-backup

Could you share further details about the setup where mounting the socket in readonly mode creates failures for you? I just tried running the tests using :ro for the socket and restarting containers and scaling services still worked as expected.

I migrated the entire test suite to use :ro mounts for sockets in #546 and everything passes as expected, which means there must be something special about your setup. Can you share a. the configuration you use and b. the error you are encountering?

@m90 Thanks for testing and all the work you have done. 😍

I think you are right: I want to execute the docker-volume-backup from a remote machine. Therefore I bound the docker socket over sshfs. There were some faults.
Sorry for the trouble.

You could think about to also make it here only ro: https://offen.github.io/docker-volume-backup/recipes/#using-mariadb-dumpmysqldump-to-prepare-the-backup

Updated the docs to always use :ro in d8ac5ae
