Percona Xtrabackup

Derived from the official Docker Debian Jessie 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

Example

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 \
mysql

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

$ docker run -it \
-v /storage/mysql-server/datadir:/var/lib/mysql \
-v /storage/backups:/backups \
--rm=true \
gleez/xtrabackup \
sh -c 'exec /xtrabackup.sh'

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/2017-02-02_07-00-28'
170202 17:07:57  innobackupex: Connection to database server closed
170202 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/
2017-02-02_07-00-28
2017-01-17_13-07-28
2017-01-17_14-02-50
