High Availability in Open Source Puppet

[coms...@gmail.com]

I want to setup a High Availability in Open Source Puppet environment for my project is there a way other than massterless architecture in open source to achieve my goal?

You can use standard Open Source solutions:

Postgresql active-passive replication with pacemaker/corosync for service IP - can postgresql also do active-active replication?
PuppetDB active passive pacemaker/corosnc with service IP
Puppet Server active-passive pacemaker/corosync with service IP
PuppetCA on external storage
external storage GlusterFS with replication or active/passive NFS/GPFS, ... pacemaker/corosync with service IP maybe with DRBD underneath
Puppet Board/Puppetexplorer: active-passive pacemaker/corosync with service IP

You can either use pacemaker/corosync or heartbeat (which ever you prefer).

Just be sure to prepare this setup by adding all required DNS ALT NAMES to your CA and to your Puppet infrastructure nodes.

hth,
Martin

Yes this is possible. The easiest way is using DNS round robin, but I prefer using a loadbalancer like keepalived or ha proxy.

There is a page in the documentation about this https://puppet.com/docs/puppetserver/5.3/scaling_puppet_server.html.
