k8s-gitops VS flux2-kustomize-helm-example

You can see how it's all put together in my k8s-gitops repo. The gist is that you add a sidecar container that starts tailscale and in my case adds an iptables rule which forwards all traffic to the app port. You can see my poor Doppler secret naming in there too where everything is using miniflux-secret.

My full workflow can be found in kasuboski/k8s-gitops. It triggers on workflow_dispatch, cron, and push to yaml files.

Any public repo show-casing a nice structure? (I am used to the Gitops world on K8s, and for the case of FluxCD for instance I would recommend this repo as a good practice to start multi-tenancy. https://github.com/fluxcd/flux2-kustomize-helm-example. I am looking for a similar "boilerplate" but for TF 😅)

My recommendation would be to take a look at their documented example of this exact scenario with various overlays for production and staging, but you could ofc add as many as you wanted. All you would do is for production point flux to the production overlay/ directory, which then calls all your normal files but overrides some values you desire. Further to this you can keep your helm chart focused on lets say the "most-common" use case, then just call it with whatever additional values you would like, E.G here in the same repo as above. Notice the values at the bottom of the yaml file which override the charts default values.

Here's an example using flux v2 to deploy to multiple environments/clusters: https://github.com/fluxcd/flux2-kustomize-helm-example

We are using flux2, which uses Kustomize under the hood. It takes a little bit of time to learn about the different CRD's which are available but once you do it works excellent. They also have an example project which sounds like it might fit your use case https://github.com/fluxcd/flux2-kustomize-helm-example

As /u/vincentdesmet mentioned Kustomize will most likely to solve your many "apps" with slightly difference issue, this is a good example https://github.com/fluxcd/flux2-kustomize-helm-example (also include helm one)
