release-please-action VS flux2-kustomize-helm-example

For automating releases based on conventional commits, I used the google-github-actions/release-please-action@v3 action.

If you are using GitHub Action, you can try this https://github.com/google-github-actions/release-please-action

Release Please Action is a GitHub action created by Google to automate releases with Conventional Commit Messages. As you merge PR's into your main branch, the action will create/update a new release branch that automatically adds your commits to a changelog and bumps the version according to your commits. When you're ready to release your changes, merging the PR will cause a new GitHub release to be created and released. We can even automate publishing to package registries like RubyGems!

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)
