MySQL with Percona Xtrabackup

Derived from the official Docker MySQL image. The image contains Percona Xtrabackup installed and a simple bash script to run the backup command.

How to use this image?

To run the backup, link it to the running MySQL container and ensure to map the following volumes correctly:

  • MySQL datadir of the running MySQL container: /var/lib/mysql
  • Backup destination: /backups


Suppose you have a MySQL container running named "mysql-server", started with this command:

$ docker run -d \
--name=mysql-server \
-v /storage/mysql-server/datadir:/var/lib/mysql \
-e MySQL_ROOT_PASSWORD=mypassword \

Then, to perform backup against the above container, the command would be:

$ docker run -it \
--link mysql-server:mysql \
-v /storage/mysql-server/datadir:/var/lib/mysql \
-v /storage/backups:/backups \
--rm=true \
severalnines/mysql-pxb \
sh -c 'exec /'

You should see Xtrabackup output on the screen. Ensure you get the “completed OK” line indicating the backup is successful:

innobackupex: Backup created in directory '/backups/2016-06-17_17-07-54'
160617 17:07:57  innobackupex: Connection to database server closed
160617 17:07:57  innobackupex: completed OK!

The container will then exit (the "run" is executed interactively) and automatically removed by Docker since we specified “--rm=true” in the command line. On the machine host, we can see the backups are there:

$ ls -1 /storage/backups/
