August 2022 Releases

It’s time for a minor release of Choria and a few related components, not a huge release as we are preparing a big refactor but still some user facing improvements - especially to the recently added App Builder component.

New Election features

We’ve used leader elections for a while internally for various components, these are backed by Choria Streams.

In this release we added an choria election command, using this command you can:

Manage, view, evict elections and leaders
Designate a particular node as a leader by managing a file under election using choria election file
Run a command under leader election using choria election run

See the Election documentation.

New Governor features

Governors can traditionally only control maximum concurrent executions, use this to limit how many nodes are actively running Puppet for example.

With a small change we were able to make them support a mode of maximum executions per period.

Imagine you have 10 nodes running the same cron job, if you need the job to run only on one of the servers every hour - essentially creating a failover pool - you can use the new --max-per-period flag.

See the Governor documentation.

Go Versions

The Go team released 1.19 last night, this means going forward we will support only go 1.18 and 1.19. The github.com/choria-io/go-choria tag v0.26.1 will be the last to work on Go 1.17.

Special thanks to Tim Meusel for his contributions to this release!

Choria Server version 0.26.1
