[Kubernetes] Dry Runs and Diff's
- Dry Runs and Diff's: Testing YAML Before Deployment
- New stuff, not out of beta yet (1.15)
- dry-run a create (client side only) 之前只能在client端使用
kubectl apply -f app.yml --dry-run
- dry-run a create/update on server 但是現在想要在server端先行測試
kubectl apply -f app.yml --server-dry-run
- see a diff visually 實際印出有差異的行數
kubectl diff -f app.yml
- END
