Package Kubenix script

[pizzapim]

As suggested in #60, I used writeScriptBin and some other helpers to package the Kubenix script. I extracted the Bash script itself and put it in its own file which makes it easier to maintain. Using wrapProgram, I set the environmental variables that were before set by string substitution.

closes #59

BTW, this doesn't link the resulting Kubernetes manifest to the derivation output anymore because there is no need. I guess this could break someone's setup, but I believe they shouldn't be using the manifest generated for the Kubenix script.

Thanks! This does look a lot neater 💯

I think this is fine to do given the front page disclaimer about being unstable. I half-implemented a CHANGELOG.md which should tag the commit whenever a new version is added. That might be a good place to capture this potentially-breaking change if you'd like.

Does this look fine?

Haven’t looked at the changes, but just wanted to make sure that users will still be able to easily access the generated manifest. Not everyone deploys via kubectl apply from their CI\CD pipeline. For example where I work, we generate manifests in the CI\CD pipeline of the source repo and push them to a manifest repo. The manifest changes are then picked up and deployed by argocd running within the cluster.

The example to generate the manifest on the documentation website is still working fine (i.e. using kubenix.evalModules and config.kubernetes.result).

Forgot to remove personal path?

[pizzapim]

Good catch, corrected

[adrian-gierakowski]

Maybe we could add the result to passthru on the derivation as passthru.manifest?

[pizzapim]

Seems fair, I've added it!

Looks good to me, for what it’s worth (I don’t have merge permissions 😄)
