Postfixadmin Kubernetes Debian 12

Question

我已经在 debian 12 上设置了一个 kubernetes 集群（第一次），并且我使用 docker mailserver 项目来安装 pod。

到目前为止一切顺利，但现在我似乎无法将 80 或 443 暴露给可从主机和/或互联网访问的网络。

我的服务

apiVersion: v1
kind: Service
metadata:
  name: postfixadmin
  namespace: mailserver
spec:
  selector:
    app: mailserver
    tier: postfixadmin
  ports:
  - port: 80
    targetPort: http

        - name: PFA_POSTMASTER_EMAIL
          value: "<my-postmaster-email-address>"
        - name: PFA_WEBMASTER_EMAIL
          value: "<my-webmaster-email-address>"
        ports:
        - containerPort: 80
          name: http

当我描述这个pod时，我得到了这个

Status:           Running
IP:               192.168.55.82
IPs:
  IP:           192.168.55.82
    Port:           80/TCP
        Host Port:      0/TCP
        State:          Running

为什么主机端口为零？

我尝试过在我的服务中使用 NodePort 或 LoadBalancer，但没有效果，我在工作节点上有这些路由
