kubectl edit opens a live Kubernetes resource in Vim, allowing an administrator to change its YAML configuration and submit the update directly to the cluster. section 6.4.3 section 8.1
Use it for focused operational changes when the resource already exists:
- Change a Service from ClusterIP to LoadBalancer by editing its type, then verify the assigned external IP with kubectl get svc. section 6.4.3
- Repair a failing Deployment by adding a required environment variable, save with :wq, and verify recovery with kubectl get po. section 8.1
- Correct a Service port when requests fail, then retry the request and inspect selectors and pod labels if connectivity remains broken. section 8.3.2
Fixing a Service port
Run kubectl edit svc nginx-svc, change the exposed port from 3306 to 80 in Vim, press Esc, type :wq, and retry curl -k http://10.96.119.24. A successful response returns the nginx welcome page. section 8.3.2
root@kind-control-plane:/# kubectl edit svc nginx-svc
service/nginx-svc edited
root@kind-control-plane:/# curl -k http://10.96.119.24
