k8s-常见错误
作者：互联网
一 网络错误
报错提示：network: failed to set bridge addr: "cni0" already has an IP address differe
解决办法：
ip link set cni0 down ip link delete cni0
二命名空间不能删除
参考：https://www.cnblogs.com/douh/p/12487577.html
1 先运行 kubectl get ns ingress-nginx -o json > rdbms.json
其中 ingress-nginx是你要删除的命名空间，然后打开rdbms.json，删除其中的spec字段
2 然后新开一个窗口运行kubectl proxy跑一个API代理在本地的8081端口
# kubectl proxy --port=8081
3 执行命令删除
curl -k -H "Content-Type: application/json" -X PUT --data-binary @rdbms.json http://127.0.0.1:8081/api/v1/namespaces/ingress-nginx/finalize
其中json文件和命名空间要和第一条命令一致。
三 解决国内无法拉取k8s镜像的问题
参考 https://www.jianshu.com/p/d42ef0eff63f
查看kubeadm config所需的镜像
$ kubeadm config images list k8s.gcr.io/kube-apiserver:v1.13.1 k8s.gcr.io/kube-controller-manager:v1.13.1 k8s.gcr.io/kube-scheduler:v1.13.1 k8s.gcr.io/kube-proxy:v1.13.1 k8s.gcr.io/pause:3.1 k8s.gcr.io/etcd:3.2.24 k8s.gcr.io/coredns:1.2.6
1：中转
首先从Kubernetes国内Docker镜像镜像，然后修改镜像的tag
sudo docker tag registry.cn-beijing.aliyuncs.com/imcto/kube-controller-manager:v1.13.1 k8s.gcr.io/kube-controller-manager:v1.13.1 sudo docker tag registry.cn-beijing.aliyuncs.com/imcto/kube-apiserver:v1.13.1 k8s.gcr.io/kube-apiserver:v1.13.1 sudo docker tag registry.cn-beijing.aliyuncs.com/imcto/kube-proxy:v1.13.1 k8s.gcr.io/kube-proxy:v1.13.1 sudo docker tag registry.cn-beijing.aliyuncs.com/imcto/kube-scheduler:v1.13.1 k8s.gcr.io/kube-scheduler:v1.13.1 sudo docker tag registry.cn-beijing.aliyuncs.com/imcto/etcd:3.2.24 k8s.gcr.io/etcd:3.2.24 sudo docker tag registry.cn-beijing.aliyuncs.com/imcto/pause:3.1 k8s.gcr.io/pause:3.1 sudo docker tag registry.cn-beijing.aliyuncs.com/imcto/coredns:1.2.6 k8s.gcr.io/coredns:1.2.6
2：修改配置kubeadm.conf
使用kubeadm配置文件，通过在配置文件中指定docker仓库地址，便于内网快速部署。
生成配置文件
kubeadm config print init-defaults ClusterConfiguration >kubeadm.conf
修改kubeadm.conf
再次查看kubeadm config所需的镜像
$ kubeadm config images list --config kubeadm.conf registry.cn-beijing.aliyuncs.com/imcto/kube-apiserver:v1.13.1 registry.cn-beijing.aliyuncs.com/imcto/kube-controller-manager:v1.13.1 registry.cn-beijing.aliyuncs.com/imcto/kube-scheduler:v1.13.1 registry.cn-beijing.aliyuncs.com/imcto/kube-proxy:v1.13.1 registry.cn-beijing.aliyuncs.com/imcto/pause:3.1 registry.cn-beijing.aliyuncs.com/imcto/etcd:3.2.24 registry.cn-beijing.aliyuncs.com/imcto/coredns:1.2.6
拉取镜像并初始化
kubeadm config images pull --config kubeadm.conf kubeadm init --config kubeadm.conf
