> One intern was told to deploy the app and I guess he made a mistake and updated k8 configs which deleted all the pods. Tell me how code reviews are supposed to catch it. So you don’t have a staging environment to check config changes before deploying to prod? Or you don't put k8s manifests (or helm charts or whatever)in source control and just update prod through CLI? And you let interns do it alone? Your problem isn't interns, it's a terrible deployment processs with weak controls. Even senior engineers are going to break prod regularly in conditions like that.
