mysql-backup

This image runs mysqldump to backup data using cronjob to folder /backup

Usage:

docker run -d \
    --env MYSQL_HOST=mysql.host \
    --env MYSQL_PORT=27017 \
    --env MYSQL_USER=admin \
    --env MYSQL_PASS=password \
    --volume host.folder:/backup
    tutum/mysql-backup

Moreover, if you link tutum/mysql-backup to a mysql container(e.g. tutum/mysql) with an alias named mysql, this image will try to auto load the host, port, user, pass if possible.

docker run -d -p 27017:27017 -p 28017:28017 -e MYSQL_PASS="mypass" --name mysql tutum/mysql
docker run -d --link mysql:mysql -v host.folder:/backup tutum/mysql-backup
