--set mongodbRootPassword=test \
--set mongodbUsername=testuser \
--set mongodbPassword=test \
--set mongodbDatabase=test-db
```
```bash
# Just in case, when need to step into dark side
kubectl port-forward --namespace dev-1 svc/mongodb 27017:27017
```
```bash
kubectl apply -f deployment.yaml -n dev-1
```
### Proceed only if you OG
```bash
kubectl rollout history deploy/k8s-rollout-deployment -n dev-1
```
```bash

# Scale a deployment “test” to 3 replicas:
kubectl scale deploy/test --replicas=3
# Watch update status for deployment “test”:
kubectl rollout status deploy/test
# Pause deployment on “test”:
kubectl rollout pause deploy/test
# Resume deployment on “test”:
kubectl rollout resume deploy/test
# View rollout history on “test”:
kubectl rollout history deploy/test
# Undo most recent update on “test”:
kubectl rollout undo deploy/test
# Rollback to specific revision on “test”:
kubectl rollout undo deploy/test --to-revision=1
```
