[K8S]kubeadm国内镜像安装方式

 

使用国内镜像站

sudo apt-get update && sudo apt-get install -y apt-transport-https curl

sudo curl -s https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -

sudo tee /etc/apt/sources.list.d/kubernetes.list <<-'EOF'
deb https://mirrors.aliyun.com/kubernetes/apt kubernetes-xenial main
EOF

sudo apt-get update

apt-cache madison kubeadm

查看过版本之后就可以指定版本安装

$ sudo apt-get install -y kubelet=1.14.0-00 kubeadm=1.14.0-00 kubectl=1.14.0-00
$ sudo apt-mark hold kubelet=1.14.0-00 kubeadm=1.14.0-00 kubectl=1.14.0-00

开机启动kubelet

sudo systemctl enable kubelet && sudo systemctl start kubelet

 

解决组件镜像无法拉取的问题

不能FQ换个方法变通处理一下

docker pull mirrorgooglecontainers/kube-apiserver:v1.14.0
docker pull mirrorgooglecontainers/kube-controller-manager:v1.14.0
docker pull mirrorgooglecontainers/kube-scheduler:v1.14.0
docker pull mirrorgooglecontainers/kube-proxy:v1.14.0
docker pull mirrorgooglecontainers/pause:3.1
docker pull mirrorgooglecontainers/etcd:3.3.10
docker pull coredns/coredns:1.3.1

 

在重新给下载的打个tag

docker tag docker.io/mirrorgooglecontainers/kube-apiserver:v1.14.0 k8s.gcr.io/kube-apiserver:v1.14.0
docker tag docker.io/mirrorgooglecontainers/kube-controller-manager:v1.14.0 k8s.gcr.io/kube-controller-manager:v1.14.0
docker tag docker.io/mirrorgooglecontainers/kube-scheduler:v1.14.0 k8s.gcr.io/kube-scheduler:v1.14.0
docker tag docker.io/mirrorgooglecontainers/kube-proxy:v1.14.0 k8s.gcr.io/kube-proxy:v1.14.0
docker tag docker.io/mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1
docker tag docker.io/mirrorgooglecontainers/etcd:3.3.10 k8s.gcr.io/etcd:3.3.10
docker tag docker.io/coredns/coredns:1.3.1 k8s.gcr.io/coredns:1.3.1

node01\node02也需要pause\kube-proxy\flannel镜像在相应的宿主机

 

初始化主节点

kubeadm init --pod-network-cidr=10.244.0.0/16

export KUBECONFIG=/etc/kubernetes/admin.conf

安装flannel网络插件

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