I am running openshift origin All-in-One setup using available binaries. Is it possible to add multiple nodes to this existing installation ?

What are the prerequisites for this, do I need to setup ssh connections between hosts?

Please do let me know how or if there is any link available for the same?

Thanks a lot!

Yes you can add additional nodes. Check this link Basically you have to export the config for this new node and move it over to that node and start using the node-config.yaml

  • Hey, thanks ,You mean manually create "node-config.yaml " for additional node, but how to start server using multiple node-config files? I already have origin installation with one master and one node.Here I start my origin server using "openshift start --master-config=openshift.local.config/master/master-config.yaml --node-config=openshift.local.config/node1/node-config.yaml" what to do in case of multiple nodes? – priyank Mar 15 '16 at 09:15
  • From the same link I gave above - To launch a node server using a node configuration file: $ openshift start node --config=/openshift.local.config/node-/node-config.yaml – cloudnoob Mar 15 '16 at 13:15
  • hey , but is it possible to run openshift using "openshift start" with two node configs? as in my previous comment. Thanks for help – priyank Mar 16 '16 at 05:07
  • Why will you start 2 nodes on the same server ? I guess I may not be understanding your requirement. The assumption is that you have already started all in one server that has master and node running on say server A . Now you have to start another node on Server B. So you login to B bring the node config tar and start node on B using "openshift start node.." – cloudnoob Mar 16 '16 at 14:57
  • Ok, thanks for clarifying, but how master will connect to node on server B then? what if I need to create apps on node B from master running in server A inside all in one mode? master and nodes should be connected to each other right? Would be very helpful if you can clarify this too? thankyou so much! – priyank Mar 17 '16 at 02:57
