Bug 1589952

Document URL: 
https://access.redhat.com/documentation/en-us/openshift_container_platform/3.9/html-single/installation_and_configuration/#ensuring-host-access

Section Number and Name: 
2.3.7. Ensuring Host Access

Describe the issue: 
The section on ensuring host access has an error in its code.

The following loop copies the ssh key for each node. However, the ssh key must also be copied on the master, otherwise, the prereq playbook fails.

# for host in master.example.com \
    node1.example.com \
    node2.example.com; \
    do ssh-copy-id -i ~/.ssh/id_rsa.pub $host; \
    done

Instead, master should be added.

# for host in master.example.com \
    master.example.com \
    node1.example.com \
    node2.example.com; \
    do ssh-copy-id -i ~/.ssh/id_rsa.pub $host; \
    done


Suggestions for improvement: 
As mentioned above, I would correct the example. I also would suggest that we should also recommend users verify that they can ssh into their hosts AND master (seems weird but yes, you must be able to ssh into your master from your master) after completion. This would ensure the process was successful.
