Hello,
I am looking for setting up Katello/Satellite master or Capsule over load
balancer or HA and DR.
Does anyone have any document to setup it ? also is satellite master runs
over CNAME ?
Thanks,
DJ
I am not sure why satellite or katello is missing this basic things like CNAME support or HA, if i have 5000 servers connecting to different capsules with single satellite master with no HA or DR , it makes difficult to recover master if it goes down.
How are you guys managing HA or DR for satellite master ??
Use https://access.redhat.com/articles/2474581 as a reference. Need to do
additional work and testing - it doesn't work out of the box!
We have a 2 node production cluster with one node in our DR site, running
pacemaker and shared SAN storage. We have a floating IP. Works.
We have 4 Capsules per region sitting behind a load balancer. Works. For
this, points to note:
- selinux is a pain (as some filesystems are shared via nfs)
- you MUST share puppet ssl and tftp boot directories as a minimum (we
share over NFS) - you need to set the puppet auth.conf files to accept connections from the
LB name - katello-consumer-ca rpms reference the node, not the LB name so you might
want to configure subscription-manager post install. - in Satellite, add the SAME lifecycles to each load balanced node.
- in Satellite register the LB name as a capsule (but DO NOT assign
lifecycles) - use this capsule in your hostgroups.
