使用最新标签向 Kubernetes 部署添加时间戳

Question

我正在尝试实现Kubernetes资源部署。为此，我创建了它deployment.yaml并service.yaml作为我的 Kubernetes 资源。latest并在我的最新标签中引用 dockerhub 注册表映像deployment.yaml. When I am doing like this, latest image is not pulling with。

所以我在部署中添加了时间戳，如下所示：

template:
 metadata:
  labels:
    app: test-kube-deployment
    date: date "+%H:%M:%S   %d/%m/%y"
spec:
  imagePullSecrets:
    - name: "regcred"
  containers:
   - name: test-kube-deployment-container
     image: spacestudymilletech010/spacestudykubernetes:latest
     imagePullPolicy: Always
     ports:
        - name: http
          containerPort: 8085
          protocol: TCP

当我在这里添加时间时，我收到如下错误，

The Deployment "test-kube-deployment" is invalid: spec.template.labels: Invalid value: "date \"+%H:%M:%S   %d/%m/%y\"": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character 

我需要进行哪些修改来定义时间戳以唯一标识我的 Docker 映像？

不要将其添加为标签，而是添加为注释。

template: 
  metadata: 
    labels: 
      app: test-kube-deployment 
    annotations: 
      date: "+%H:%M:%S %d/%m/%y"

PD.- 您收到错误是因为标签不接受 +、% 和 : 字符。
