首先就是安装，https://kubernetes.io/docs/setup/independent/install-kubeadm/
准备三台 vm（4cpu-8G）
10.88.1.170
10.88.1.171
10.88.1.172
docker 略过，先解决源的问题
apt-get update && apt-get install -y apt-transport-https curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add - cat </etc/apt/sources.list.d/kubernetes.list deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main EOF apt-get update apt-get install -y kubelet kubeadm kubectl apt-mark hold kubelet kubeadm kubectl
当然要 ansible k8s -uroot -a “xxx”
二、初始化master(170)
cat /etc/default/kubelet KUBELET_EXTRA_ARGS=--cgroup-driver=
docker pull hulupiao/kube-apiserver-amd64:v1.11.2 docker pull hulupiao/kube-controller-manager-amd64:v1.11.2 docker pull hulupiao/kube-scheduler-amd64:v1.11.2 docker pull hulupiao/kube-proxy-amd64:v1.11.2 docker pull hulupiao/pause:3.1 docker pull hulupiao/etcd-amd64:3.2.18 docker pull hulupiao/coredns:1.1.3 docker tag hulupiao/kube-apiserver-amd64:v1.11.2 k8s.gcr.io/kube-apiserver-amd64:v1.11.2 docker tag hulupiao/kube-controller-manager-amd64:v1.11.2 k8s.gcr.io/kube-controller-manager-amd64:v1.11.2 docker tag hulupiao/kube-scheduler-amd64:v1.11.2 k8s.gcr.io/kube-scheduler-amd64:v1.11.2 docker tag hulupiao/kube-proxy-amd64:v1.11.2 k8s.gcr.io/kube-proxy-amd64:v1.11.2 docker tag hulupiao/pause:3.1 k8s.gcr.io/pause:3.1 docker tag hulupiao/etcd-amd64:3.2.18 k8s.gcr.io/etcd-amd64:3.2.18 docker tag hulupiao/coredns:1.1.3 k8s.gcr.io/coredns:1.1.3 #不要问我为什么这么费劲,如果有代理可以参考 https://docs.docker.com/config/daemon/systemd/#httphttps-proxy kubeadm init --kubernetes-version=1.11.2 --apiserver-advertise-address 10.88.1.170 --pod-network-cidr=10.88.1.0/24
