Deployment or Rollout

nginx Deployment

특별히 argocd의 Rollout을 쓰는게 아니라면 Deployment로

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  labels:
    type: frontend
spec:
  replicas: 1
  selector:
    matchLabels:
      type: frontend
  template:

          image: busybox
          command: ["sh", "-c", "echo test > /usr/share/nginx/html/test.html"]
          volumeMounts:
            - name: nginx-vol
              mountPath: /usr/share/nginx/html
      containers:
