一、MASTER节点配置

1.初始化k8s集群

为了应对网络不畅通的问题，我们国内网络环境只能提前手动下载相关镜像并重新打tag

[root@k8s-master ~]# docker pull mirrorgooglecontainers/kube-apiserver:v1.13.1 [root@k8s-master ~]# docker pull mirrorgooglecontainers/kube-controller-manager:v1.13.1 [root@k8s-master ~]# docker pull mirrorgooglecontainers/kube-scheduler:v1.13.1 [root@k8s-master ~]# docker pull mirrorgooglecontainers/kube-proxy:v1.13.1 [root@k8s-master ~]# docker pull mirrorgooglecontainers/pause:3.1 [root@k8s-master ~]# docker pull mirrorgooglecontainers/etcd:3.2.24 [root@k8s-master ~]# docker pull coredns/coredns:1.2.6 [root@k8s-master ~]# docker pull registry.cn-shenzhen.aliyuncs.com/cp_m/flannel:v0.10.0-amd64  [root@k8s-master ~]# docker tag mirrorgooglecontainers/kube-apiserver:v1.13.1 k8s.gcr.io/kube-apiserver:v1.13.1 [root@k8s-master ~]# docker tag mirrorgooglecontainers/kube-controller-manager:v1.13.1 k8s.gcr.io/kube-controller-manager:v1.13.1 [root@k8s-master ~]# docker tag mirrorgooglecontainers/kube-scheduler:v1.13.1 k8s.gcr.io/kube-scheduler:v1.13.1 [root@k8s-master ~]# docker tag mirrorgooglecontainers/kube-proxy:v1.13.1 k8s.gcr.io/kube-proxy:v1.13.1 [root@k8s-master ~]# docker tag mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1 [root@k8s-master ~]# docker tag mirrorgooglecontainers/etcd:3.2.24 k8s.gcr.io/etcd:3.2.24 [root@k8s-master ~]# docker tag coredns/coredns:1.2.6 k8s.gcr.io/coredns:1.2.6 [root@k8s-master ~]# docker tag registry.cn-shenzhen.aliyuncs.com/cp_m/flannel:v0.10.0-amd64 quay.io/coreos/flannel:v0.10.0-amd64  [root@k8s-master ~]# docker rmi mirrorgooglecontainers/kube-apiserver:v1.13.1 [root@k8s-master ~]# docker rmi mirrorgooglecontainers/kube-controller-manager:v1.13.1 [root@k8s-master ~]# docker rmi mirrorgooglecontainers/kube-scheduler:v1.13.1 [root@k8s-master ~]# docker rmi mirrorgooglecontainers/kube-proxy:v1.13.1 [root@k8s-master ~]# docker rmi mirrorgooglecontainers/pause:3.1 [root@k8s-master ~]# docker rmi mirrorgooglecontainers/etcd:3.2.24 [root@k8s-master ~]# docker rmi coredns/coredns:1.2.6 [root@k8s-master ~]# docker rmi registry.cn-shenzhen.aliyuncs.com/cp_m/flannel:v0.10.0-amd64

然后再在Master节点上执行如下命令初始化k8s集群：

[root@k8s-master ~]# kubeadm init --kubernetes-version=v1.13.1 --apiserver-advertise-address 192.168.1.9 --pod-network-cidr=10.244.0.0/16

kubernets-version:用于指定k8s版本
apiserver-advertise-address:用于指定使用master的哪个network interface进行通信，如果不指定的话，则kubeadm会自动选择具有默认网关的interface
pod-network-cidr:用于指定pod的网络范围，该参数使用依赖于使用的网络方案，本文将会使用经典的flannel网络方案
