kubernetes workload (deployment) manifest creation!
in this episode of #KubeTuesday 2025-08-05
i would like to show you something simple.

Declarative definition of the *goal*! Create one or more pods running copies of the same software component (for high availability, load distribution, performance, etc.).

Again, as with single pods, you don’t need to know how to write Kubernetes YAML manifests from scratch.
Note: besides my `-l` typo in this demo, i should have used `tail` instead of `head` to show you the commands... apologies.

Here are a few commands to consider:
kubectl create deployment myapp --image=nginx --port=80 --dry-run=client -o yaml myapp.yaml
kubectl apply -f myapp.yaml
kubectl get deployment myapp
kubectl get replicasets -l=app=myapp
kubectl get po -l=app=myapp
kubectl scale deployment myapp --replicas=3
kubectl get replicasets -l=app=myapp # again
kubectl get po -l=app=myapp # again
kubectl scale deployment myapp --replicas=1
kubectl get po -l=app=myapp # yet again

Compare that to the singleton pod technique from #kubetuesday 2025-07-25
kubectl run mypod --image=nginx --dry-run=client -o yaml mypod.yaml
