I'm not able to tell by the screens and info, but is it possible to customize the exec command?
What I'm looking for is an option to create a backup from MySQL database running in a container, the backup command would be something like this:
Bash:
docker exec <CONTAINER NAME> /usr/bin/mysqldump -u <DATABASE USERNAME> --password=<DATABASE USER PASSWORD> <DATABASE NAME> > backup.sql
My guess is that it will try to just execute the mysqldump command which is not found since is not installed in the host.
