Hi,

I am new to Rancher and setting it up.  
I have three rhel nodes in Azure which have the docker engine and ran the command below on all three machines:

docker run -d --restart=unless-stopped -p 8080:8080 -p 9345:9345 rancher/server   
–db-host [myhost.example.com](http://myhost.example.com) --db-port 3306 --db-user username --db-pass password --db-name cattle   
–advertise-address

Is it possible to have Rancher running on 3 nodes without the external DB but with a “internal/ in memory” DB that is synced between the 3 nodes?

With kind regards,

Bram

No, the internal DB is pretty much standard mysql and not configured for replication.
