Simple MySQL Replication using CoreOS and Percona Galera Cluster

Once you have a working CoreOS environment you should beable to submit the following fleet units to startup and configure your Galera Cluster.

Requirements

• CoreOS or similar base OS
• etcd service
• fleet service
• flannel service

Template needs modification

The file [email protected] should be modified to reflect the proper endpoints you need.

Fleet Units

There are multiple fleet-units

• [email protected] = This starts up the Galera docker container
• [email protected] = Reports to etcd the internal IP

Warning

You really should change the default passwords within [email protected]. I haven't figured out a good way to have ansible or saltstack be the actually process that submits the fleet-units. So for now while I'm testing this is how the password are being done.

If you don't change them thats your call. These are just templates.

Submitting fleet-unit files

Submit the fleet-unit files in the following order.

fleetctl submit [email protected]
fleetctl submit [email protected]
