Alpine image with mysql-client installed. Helpful if you just want to execute a mysqldump from docker
Use the following sample command, but first replace ${PORT}, ${HOST}, ${USER}, ${PASSWORD}, ${DATABASE} with your desired values. Or you can alternatively complete the command passing Docker these environment variables using the -e option, like: -e USER=aUsername.
docker run --rm -v "$PWD/data":/data --name mysql-client byteflair/mysql-client sh -c "mysqldump -P${PORT} -h${HOST} -R -u${USER} -p${PASSWORD} ${DATABASE} > /data/dump.sql"
