# mysql-cron-backup

This image runs mysqldump to backup your databases periodically using cron. Data is dumped to `/backup` so you can mount your backup volumes in this path.

## Usage:

  docker run -d \
    --env MYSQL_USER=admin \
    --env MYSQL_PASS=password \
    --link mysql
    --volume /path/to/my/host/folder:/backup
    fradelg/mysql-backup
