[K8S]kubeadm國内鏡像安裝方式

使用國内鏡像站

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

檢視過版本之後就可以指定版本安裝

$ 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

開機啟動kubelet

sudo systemctl enable kubelet && sudo systemctl start kubelet

解決元件鏡像無法拉取的問題

不能FQ換個方法變通處理一下

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

在重新給下載下傳的打個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鏡像在相應的主控端

初始化主節點

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

export KUBECONFIG=/etc/kubernetes/admin.conf

安裝flannel網絡插件

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