You Should Know:
To get started with Kubernetes Deployment and ReplicaSet, here are some essential commands and steps:
1. Create a Deployment:
kubectl create deployment my-deployment --image=nginx
This command creates a deployment named `my-deployment` using the `nginx` image.
2. Scale a Deployment:
kubectl scale deployment my-deployment --replicas=3
This scales the deployment to 3 replicas.
3. Check Deployment Status:
kubectl get deployments
This command lists all deployments and their status.
4. Describe a Deployment:
kubectl describe deployment my-deployment
This provides detailed information about the deployment.
5. Update a Deployment:
kubectl set image deployment/my-deployment nginx=nginx:1.19
This updates the image used in the deployment to nginx:1.19.
6. Rollback a Deployment:
kubectl rollout undo deployment/my-deployment
This rolls back the deployment to the previous version.
7. Create a ReplicaSet:
kubectl create -f replicaset.yaml
This command creates a ReplicaSet using a YAML file.
8. Check ReplicaSet Status:
kubectl get replicasets
This lists all ReplicaSets and their status.
9. Delete a Deployment:
kubectl delete deployment my-deployment
This deletes the specified deployment.
10. Delete a ReplicaSet:
kubectl delete replicaset my-replicaset
This deletes the specified ReplicaSet.
