版本：

　　docker: 19.03.5

　　kubernetes: 1.17.0

　　istio: 1.4.3

步骤一：给ubuntu换源

步骤二：装docker

sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

sudo apt-get update

sudo apt-get install docker-ce=5:19.03.5~3-0~ubuntu-xenial

sudo docker --version

步骤三：装kubernetes(k8s)

sudo apt install -y kubelet-1.17.0 kubeadm-1.17.0 kubectl-1.17.0

如果不能执行，就把版本号去掉，默认安装最新版本

kubeadm config images list

显示需要拉取的Images，如果提示权限，前面加sudo

docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver:v1.17.0docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-controller-manager:v1.17.0docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-scheduler:v1.17.0docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-proxy:v1.17.0docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.1docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.4.3-0docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.6.5

docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.1 k8s.gcr.io/pause:3.1docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver:v1.17.0 k8s.gcr.io/kube-apiserver:v1.17.0docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-controller-manager:v1.17.0 k8s.gcr.io/kube-controller-manager:v1.17.0docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-scheduler:v1.17.0 k8s.gcr.io/kube-scheduler:v1.17.0docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-proxy:v1.17.0 k8s.gcr.io/kube-proxy:v1.17.0docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.4.3-0 k8s.gcr.io/etcd:3.4.3-0docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.6.5 k8s.gcr.io/coredns:1.6.5

执行Init

kubeadm init --kubernetes-version=v1.17.0 --pod-network-cidr 192.168.0.0/16

出现cgroupd有关错误：

cd /etc/dockersudo touch daemon.jsonsudo vim daemon.json// 添加内容：{ "exec-opts":["native.cgroupdriver=systemd"]}

sudo service docker restartsudo systemctl status docker

出现swap有关错误：

swapoff -a

再次执行init命令：

按照提示添加：

执行完继续执行：

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

kubectl get pod -n kube-system　　// 查看状态

步骤四：安装istio

我是直接安装的最新版本

mkdir istiocd istiocurl -L https://git.io/getLatestIstio | sh -

下载速度很慢，建议...

下载完后在istio目录下会有个istio-1.4.3文件夹

vim /etc/profile

添加上面提示的路径。

source /etc/profileecho $PATH

istioctl verify-install

查看版本：

istioctl version --remote=false

k8s和istio安装成功！
