Kubernetes 错误汇总（持续更新）

Kubernetes 错误汇总（持续更新）

问题一、unable to fetch the kubeadm-config ConfigMap: failed to get config map: Unauthorized

[root@k8s-store01 ~]# kubeadm join 10.0.0.31:6443 --token 1euadv.48cjve19biy33b9m --discovery-token-ca-cert-hash sha256:295acb22b65296410968d040cfbb326642d2e3b177ccbc3626765a0ada6fa9ff [preflight] Running pre-flight checks [WARNING SystemVerification]: this Docker version is not on the list of validated versions: 19.03.5. Latest validated version: 18.09 [preflight] Reading configuration from the cluster... [preflight] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -oyaml' error execution phase preflight: unable to fetch the kubeadm-config ConfigMap: failed to get config map: Unauthorized

解决办法是： token已经过期了，该token默认是24小时内有效果的，所以需要在master节点重新生成token

[root@k8s-master01 ~]# kubeadm token create ottwfk.al3ksj32yeqogk9y [root@k8s-master01 ~]# kubeadm token list TOKEN TTL EXPIRES USAGES DESCRIPTION EXTRA GROUPS 1euadv.48cjve19biy33b9m 2019-12-08T16:17:03+08:00 authentication,signing system:bootstrappers:kubeadm:default-node-token ottwfk.al3ksj32yeqogk9y 23h 2019-12-10T13:20:57+08:00 authentication,signing system:bootstrappers:kubeadm:default-node-token

问题二：repository does not exist or may require 'docker login': denied: requested access to the resource is denied

[root@k8s-master01 ~]# kubectl describe pod nginx-demo Normal Scheduled 15m default-scheduler Successfully assigned default/nginx-demo to k8s-node03 Normal BackOff 14m (x6 over 15m) kubelet, k8s-node03 Back-off pulling image "10.0.0.33/base_images/nginx:1.13" Normal Pulling 13m (x4 over 15m) kubelet, k8s-node03 Pulling image "10.0.0.33/base_images/nginx:1.13" Warning Failed 13m (x4 over 15m) kubelet, k8s-node03 Failed to pull image "10.0.0.33/base_images/nginx:1.13": rpc error: code = Unknown desc = Error response from daemon: pull access denied for 10.0.0.33/base_images/nginx, repository does not exist or may require 'docker login': denied: requested access to the resource is denied Warning Failed 13m (x4 over 15m) kubelet, k8s-node03 Error: ErrImagePull Warning Failed 4m56s (x43 over 15m) kubelet, k8s-node03 Error: ImagePullBackOff

解决方法是：node节点没有权限从harbor拉取镜像，所以需要在master节点进行授权

[root@k8s-master01 ~]# kubectl create secret docker-registry harbor-secret --namespace=default --docker-server=10.0.0.33 --docker-username=admin --docker-password=Harbor12345 // 添加授权 [root@k8s-master01 ~]# cat web-demo.yaml apiVersion: v1 kind: Pod metadata: name: nginx-demo labels: env: test spec: containers: - name: nginx image: 10.0.0.33/base_images/nginx:1.13 imagePullPolicy: Always imagePullSecrets: - name: harbor-secret nodeSelector: app: k8s-node03
