Support for multiple static agent containers #38

Closed brettcurtis closed 2 years ago

brettcurtis commented 2 years ago

Thinking it might be useful to have support for multiple static agents. For example, I have some workflows that need gocd/gocd-agent-ubuntu-20.04 and some that need to run docker so I need gocd/gocd-agent-docker-dind. I'm avoiding using elastic agents here as some persistence is needed for Gradle so workflows don't take so long.

Am I looking at this wrong or is there a current way to solve my problem?

To meet the direct requirement, you can install the chart again with a different release name and server disabled (multiple values files effectively). I think that would be the more canonical way to achieve such a thing in Helm.

In my previous setup we had agent-only uses of the chart and it worked fine. If there's anything that gets in the way of doing that we can probably address those issues pretty easily.

Ok, that seems reasonable. I'll give it a go, thanks for the help!

If you don't want to install and deploy two releases (so you can upgrade atomically), the other alternative might be to use a custom umbrella chart with an aliased dependency in Chart.yaml for the extra agent subchart. I haven't tried that with 2xgocd but should work.
