现象

登陆已有的pod访问服务,出现:

curl: (7) Failed to connect to 10.106.149.49 port 80: Connection refused

10.106.149.49是CLUSTER-IP

~# kubectl get svc
NAME         TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1       <none>        443/TCP   6h27m
kubia-svc    ClusterIP   10.106.149.49   <none>        80/TCP    63s

解决

1. 如果是通过env方式传递的话,服务应该先于pod创建
2. 服务的标签选择器和pod的标签要一致
3. 检查你的pod是否没有被rc或rs托管
   而是像下面的yaml一样直接创建了一个pod,是不行的,Kind要为RelicaSet或Deployment,我就是栽在这上面了

apiVersion: v1
kind: Pod
metadata:
  name: kubia2
  labels: 
    app: kubia1
spec:
  containers:
  - image: registry.cn-hangzhou.aliyuncs.com/我私人的仓库/kubia
    name: kubiacontainers
    ports:
    - containerPort: 8080
      protocol: TCP
      name: http
  imagePullSecrets:
  - name: aliyun
