k8s安装网络插件镜像下载不了问题

下面是本人在帮好友安装k8s过程中在安装网络插件这里碰到的问题

使用kubectl apply -f kube-flannel.yml安装flannel网络插件

安装完之后是要等个一阵子的，但是等了十分钟后发现节点状态还是为Noready

通过journalctl -f -u kubelet 查看kubelet日志发现报错

systemctl status kubelet 查看报错如下

# systemctl status kubelet

还是说报没有安装网络插件的问题。只能说明网络插件安装失败了

查看kube-flannel pod节点状态 Terminating

[root@master k8s]# kubectl get pod -n kube-flannel
NAME                    READY   STATUS        RESTARTS   AGE
kube-flannel-ds-v8xw5   0/1     Terminating   0          33m

查看 kube-flannel 启动过程看Events事件

[root@master k8s]# kubectl describe pod -n kube-flannelEvents:Type    Reason     Age   From               Message----    ------     ----  ----               -------Normal  Scheduled  42s   default-scheduler  Successfully assigned kube-flannel/kube-flannel-ds-z45kj to masterNormal  Pulled     42s   kubelet            Container image "docker.io/rancher/mirrored-flannelcni-flannel-cni-plugin:v1.1.0" already present on machineNormal  Created    42s   kubelet            Created container install-cni-pluginNormal  Started    42s   kubelet            Started container install-cni-pluginNormal  Pulling    41s   kubelet            Pulling image "docker.io/rancher/mirrored-flannelcni-flannel:v0.20.0"

发现在 pulling image “docker.io/rancher/mirrored-flannelcni-flannel:v0.20.0” 这个地方一直卡着。

原因是这是一个国外的镜像访问不了，有点慢。想办法替换其它可以下载的镜像

搜索一下

[root@master k8s]# docker search flannel

选择拉取一个 jmgao1983/flannel 与 lizhenliang/flannel 都行

docker pull jmgao1983/flannel

在线编辑 kube-flannel.yml

kubectl edit -f kube-flannel.yml

 initContainers:- name: install-cni-plugin#image: flannelcni/flannel-cni-plugin:v1.1.0 for ppc64le and mips64le (dockerhub limitations may apply)image: docker.io/rancher/mirrored-flannelcni-flannel-cni-plugin:v1.1.0command:- cpargs:- -f- /flannel- /opt/cni/bin/flannelvolumeMounts:- name: cni-pluginmountPath: /opt/cni/bin- name: install-cni#image: flannelcni/flannel:v0.20.0 for ppc64le and mips64le (dockerhub limitations may apply)image: jmgao1983/flannelcommand:- cpargs:- -f- /etc/kube-flannel/cni-conf.json- /etc/cni/net.d/10-flannel.conflistvolumeMounts:- name: cnimountPath: /etc/cni/net.d- name: flannel-cfgmountPath: /etc/kube-flannel/containers:- name: kube-flannel#image: flannelcni/flannel:v0.20.0 for ppc64le and mips64le (dockerhub limitations may apply)image: jmgao1983/flannel

将 docker.io/rancher/mirrored-flannelcni-flannel:v0.20.0 换成 jmgao1983/flannel

再次查看

kubectl describe pod -n kube-flannel

看到 Started container kube-flannel 表示启动成功

再次查看nodes状态

[root@master k8s]# kubectl get pod -n kube-flannel
