HA (high availability) Jenkins setup across 2 sites

[John]

Hello everyone,

We are doing a new implementation of Jenkins and interested in ways to create an HA setup.
I can think of a few ways:
1. Stay with the regular XML style configs with shared filesystem (DRBD or NFS?)
2. Use DB PostGres/MySQL with WAN replication.

We are OK with having the 2nd master in standby cold HA so it can be brought up manually.

What are the recommendations?

Thanks
John

Hi John: 

In full disclosure, I work @ CloudBees, but I'd be remiss not to mention HA is one of the core features of our offering: https://www.cloudbees.com/products/cloudbees-jenkins-platform/enterprise-edition/features/high-availability-plugin

There are also some future plans under discussion around a more pluggable file system solution that may help make this easier / even more scalable in the future.

Happy to discuss further offline if you'd like.
