I'm going to use this opportunity to get up on my soap-box and talk about helm, the "recommended" way to install kubernetes packages. Helm is not a useful abstraction, and needs to change in a BIG way before I consider using it over k8s_raw and ansible. My main complaint with helm is that it doesn't allow one to develop decent abstractions over the core kubernetes resources. IMO it needs to move away from `gotpl` and…

Have you taken a look at some of the Helm 3 proposals? One of the points that talks about this exact use case is the concept of a "library chart", which is a way to define a block of code once and import it into another chart. In your case you could then define a block of code which will spit out a set of kubernetes labels that is shared across all your charts.

Your other point about it being difficult to interact with the kubernetes and Tiller APIs in any other language than Go is true, though it isn't necessarily a Helm Thing. This is a Kubernetes Thing. Tiller's going away in Helm 3 so the side effect should be that Helm will be much simpler to extend.

Agreed. Unstructured text templating to generate structures YAML is a terrible idea, which was previously shown with Ansible and Salt. (Salt provides a way to generate its YAML declaratively using Python, which seems to me a much better idea. Not sure about Ansible?) I think Jsonnet is an intriguing idea here. Jsonnet is not well known, but apparently popular inside Google. It has variables and iteration, and allows…

Helm Version 3 will adopt CRDs for release and application state. There will no longer be a server side component (tiller). It should be much easier to integrate other tools or templating systems with V3. https://github.com/kubernetes-helm/community/blob/master/hel...

Interesting, but I never saw Tiller as an issue. Quite the opposite, I want less client and more server.

https://keel.sh/ is also a great release manager / chatops framework. edit: I had keel.io which is some random company. The site I wanted was keel.sh

I'll admit: I'm sold.
