Troubleshooting Argo CD

2. Problem: My YAML isn’t formatted correctly
   1. In VS Code, ensure you have the Kubernetes extension installed
   2. It’ll check syntax as you type, including Argo resources, with popup definitions
   3. ProTip: You can add it as a suggested extension in your K8s YAML repos
   4. Require GHA K8s linter to pass before PRs can merge. (Super-linter) also runs that
   5. Manually try kubectl apply --dry-run=server -f file.yaml on K8s with Argo CD
      1. ProTip: you could do this in GHA as part of a "smoke test"
         1. Setup K3d Action
         2. Install Argo CD with one-liner and maybe a config file, if needed
         3. Apply yamls from PR diff, or maybe only if specific YAML dirs changed
