Deploying MySQL and WordPress Docker Containers through Marathon

[su...@accenture.com]

Hi ,

In case we are killing one the instances running through Marathon UI. It is able to bring up another replacing it.

So, would like to know is it a replication of the previous instance which was killed or it's a new one.

For example, if we are running a MySQL application through Marathon UI  and try on of its instance to kill. Will the information saved in the database will be remain in the new one replacing it.


Thanks

The MySQL service automatically clusters with a single primary and any number of replicas. If a replica fails, Marathon will replace it, and the new instance will automatically bootstrap itself with a copy of the DB and join the cluster. If the primary should fail, one of the replicas will be promoted to to primary, and Marathon will launch a new instance to replace the replica.
