问题1：

• kube-apiserver: E0309 14:25:24.889084 66289 instance.go:392] Could not construct pre-rendered responses for ServiceAccountIssuerDiscovery endpoints. Endpoints will not be enabled. Error: issuer URL must use https scheme, got: api
• kube-apiserver: E0309 14:26:21.064219 66289 controller.go:184] Get "https://10.1.1.11:6443/api/v1/namespaces/default/endpoints/kubernetes": dial tcp 10.1.1.11:6443: connect: connection refused

解决问题：

vim /usr/local/k8s/apiserver/conf/apiserver.conf
--service-account-signing-key-file=/usr/local/k8s/ca/ca-key.pem \
--service-account-issuer=https://kubernetes.default.svc.cluster.local \

问题2：

• Unable to remove old endpoints from kubernetes service: StorageError: key not found, Code: 1, Key: /registry/masterleases/10.1.1.11, ResourceVersion: 0, AdditionalErrorMsg:

解决问题：

• 可以从下面的图片中看出，停止服务的时候key被删掉了，但启动的时候又要去获取。

问题3：pod中的时间分区和宿主机的不同

解决问题方法一：配置环境变量

apiVersion: apps/v1
kind: Deployment
metadata:
spec:
  template:
    spec:
      containers:
        env:
        - name: TZ    #添加该环境变量
          value: Asia/Shanghai

解决问题方法二：挂载时间文件

apiVersion: apps/v1
kind: Deployment
metadata:
spec:
  template:
    spec:
      containers:
        volumeMounts:
        - name: time-mount
          mountPath: /etc/localtime    #将Asia/Shanghai挂载的容器中
      volumes:
      - name: time-mount
        hostPath:
          path: /usr/share/zoneinfo/Asia/Shanghai

问题4：创建的ingress不正常

问题描述：

• ingress-nginx-controller-v1.0.4安装正常
  • W0406 16:14:36.130966       6 client_config.go:615] Neither --kubeconfig nor --master was specified.  Using the inCluster报错不用管。
• 创建的ingress有问题

//ADDRESS没有获取地址
]# kubectl get ingress -o wide
NAME         CLASS    HOSTS       ADDRESS   PORTS   AGE
my-ingress   <none>   localhost             80      118s

//日志开头虽然是I，但是它是有问题的
]# kubectl logs ingress-nginx-controller-5767958868-k9576  -n ingress-nginx
I0407 01:03:50.088521       6 store.go:342] "Ignoring ingress because of error while validating ingress class" ingress="default/my-ingress" error="ingress does not contain a valid IngressClass"

解决问题：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: "nginx"    #加上该注解
spec:

1

#                                                                                                                          #
