shortlink VS argocd-autopilot

More details: - https://github.com/shortlink-org/shortlink/tree/main/ops/argocd - https://github.com/shortlink-org/shortlink/tree/main/ops/gitlab

As written above, CI/CD is not the hardest part; there are many ready-made tutorials for any combination of programming languages, engineering cultures, and tools deployment (Gitlab, Github, etc.). On Github, there are many ready-made examples of CI/CD. You can study the solutions and make your own based on them—for example, set up a CI/CD deploy/update a WordPress blog. I'm spoiling my pet project to maintain my skills, for example - https://github.com/shortlink-org/shortlink/tree/main/ops It includes: - gitlab CI/CD: quite a complex pipeline with tests, builds, and deployment - GitHub action: basic linking - Argo CD: gitops, deployment of different applications to k8s

I think that for real projects it is better to separate argocd and our applications. For my pet project I use one mono repository: - `ops/Helm` - description of all helm-charts - `ops/argocd` - description of argocd applications that refer to helm charts So when you update a helm chart it is immediately applied to the k8s cluster. You can see my example - https://github.com/shortlink-org/shortlink

I use Argo CD Autopilot which bootstraps Argo CD in a self-managing structure. If nothing else, copy the repo structure https://github.com/argoproj-labs/argocd-autopilot

We use the same approach internally and we fully open-sourced our solution at https://argocd-autopilot.readthedocs.io/en/stable/

I recommend utilising Autopilot a companion project that not only installs Argo CD but also commits all configurations to git so Argo CD can maintain itself using GitOps.

Check https://argocd-autopilot.readthedocs.io/en/stable/ It is an installer that does exactly that. It installs ArgoCD, sets it up to manage itself and offers a suggested bootstrap for your applications

Checkout the ArgoCD autopilot if you're using kustomize rather than helm
