Use master as worker nodes #1

Open ronanb3 opened 4 years ago

ronanb3 commented 4 years ago

Starting with OCP 4.5, a configuration with 3 nodes. I did an inventory keeping a worker list and removing any entry in it. It fails if I remove the worker entry.

The cluster builds well but I cannot make the console works. It seems there is an issue with the routing.

The issue comes from the haproxy configuration.

Here is the configuration working.

backend wrkhttp
    mode http
    balance roundrobin
    option forwardfor
    server master-1 10.99.92.62:80 check
    server master-2 10.99.92.63:80 check
    server master-3 10.99.92.64:80 check
backend wrkhttps
    mode tcp
    balance roundrobin
    server master-1 10.99.92.62:443 check
    server master-2 10.99.92.63:443 check
    server master-3 10.99.92.64:443 check

My inventory configuration

[all:children]
masters
workers

 ...

[masters]
192.168.1.101 host="master-1" mac="00:50:52:54:60:04"
192.168.1.102 host="master-2" mac="00:50:52:54:60:05"
192.168.1.103 host="master-3" mac="00:50:52:54:60:06"

[workers]

If I remove workers totally there is an error in one of the script.

Tested installation with just masters and this seems to work correctly. We will make the following changes:
