TLDR: my CICD choice: argo-cd and argo-workflow Since I chose argocd and github action as our CICD pipeline two years ago, I rarely thought about other choices and the reason I made the choices. Recently I leant from several sources that jenkins is still widely used, it arouse my interest on this subject again. I reconsidered my choice and layed out the reasons here for my future references. I didn’t have a good impression with java in my past java projects.
