[Kubernetes] Run, Expose, and Create Generators
- Run, Create, and Expose Generators
- These commands use helper templates called "generators"
- Every resource in Kubernetes has a specification or "spec"
kubectl create deployment sample --image nginx --dry-run -o yaml
- You can output those templates with
--dry-run -o yaml - You can use those YAML defaults as a starting point
- Generators are "opinionated default"
- Generator Examples
- Using dry-run with yaml output we can see the generators
kubectl create deployment test --image nginx --dry-run -o yaml- Job的restartPolicy是Never，
kubectl create job test --image nginx --dry-run -o yaml kubectl expose deployment/test --port 80 --dry-run -o yaml, You need create a deployment before it works( kubectl create deployment test --image nginx )
- End
- Using dry-run with yaml output we can see the generators
