For those who are interested in containers, I'd like to share a Dockerimage that we've produced in Red Hat in cooperation with OpenShift guys.And will be really glad for any feedback you have.

The image can be used in OpenShift or run directly. But what I findreally interesting is a PoC implementation of master/slave, that is notdocumented as official feature yet, but it can be used as simple as that:


  docker pull centos/mariadb-100-centos7

  docker run -e MYSQL_MASTER_USER=master \
             -e MYSQL_MASTER_PASSWORD=master \
             -e MYSQL_DATABASE=db \
             -e MYSQL_USER=user \
             -e MYSQL_PASSWORD=foo \
             -e MYSQL_ROOT_PASSWORD=rootpasswd \
             -d centos/mariadb-100-centos7 mysqld-master

  docker run -e MYSQL_MASTER_USER=master \
             -e MYSQL_MASTER_PASSWORD=master \
             -e MYSQL_DATABASE=db \
             -e MYSQL_MASTER_SERVICE_NAME=<master_ip> \
             -d centos/mariadb-100-centos7 mysqld-slave

As said above, any feedback welcome :)
