Lab Setup¶

Here is the setup we will leverage to work on the RedHat OpenShift environment.

In the existing environment, here is the setup you’re working within:

In case you don’t use the Ravello BluePrint, here are a few things to know that could be useful (if you want to reproduce this in another environment)

Here are the different things to take into accounts during this installation guide:

• We are using RHEL in this blueprint

• We updated on all the nodes the /etc/hosts file so that each node is reachable via its name

  Example of our hosts file:

  [root@ose-node01 ~]# cat /etc/hosts
  127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
  10.10.199.100 ose-mstr01 ose-mstr01.f5.local
  10.10.199.101 ose-node01 ose-node01.f5.local
  10.10.199.102 ose-node02 ose-node02.f5.local
  

• On ose-mstr01, we created some ssh keys for user that we copied on all the nodes. This way you can use ose-mstr01 as needed to connect to all nodes without authentication if wanting to jump around using ssh i.e. ssh root@10.10.199.101 from ose-mstr01
