Kubernetes 快速安装部署

这应该是网上成功率比较高的一个快速部署方案
以下部署具体到了详细的版本，部署很容易成功，但时间久了会导致版本有点落后

master 和 slave

添加修改源

vim /etc/apt/sources.list

# deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted

apt-get install -y apt-transport-https
curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add -

cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main

apt-get update

安装 docker，kubernetes

# 关闭Swap，机器重启后不生效 swapoff -a
# 修改/etc/fstab 永久关闭Swap

apt-get install docker.io=18.09.7-0ubuntu1~16.04.4
apt-get install kubernetes-cni=0.6.0-00
apt-get install kubeadm=1.12.0-00 kubelet=1.12.0-00 kubectl=1.12.0-00

提前导入指定版本 docker 镜像

docker pull k8s.gcr.io/kube-controller-manager:v1.12.0
docker pull k8s.gcr.io/kube-apiserver:v1.12.0
docker pull k8s.gcr.io/kube-scheduler:v1.12.0
docker pull k8s.gcr.io/kube-proxy:v1.12.0
docker pull k8s.gcr.io/etcd:3.2.24
docker pull k8s.gcr.io/coredns:1.2.2
docker pull k8s.gcr.io/pause:3.1

master

kubernetes master 初始化

kubeadm init

mkdir -p $HOME/.kube
cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"

# kubectl taint node master node-role.kubernetes.io/master:NoSchedule-

# (往master上调度)

slave

kubernetes slave 节点加入

master上初始化的时候有下面这条命令

kubeadm join 172.30.81.69:6443 --token 1oavg9.35jc5db02ntw82ux --discovery-token-ca-cert-hash sha256:f68e58f0dbb50871102890bf57f7175ab8422ed34561ea22b544075e9e43c58a

master

kubernetes 是否部署成功

kubectl get pods --all-namespaces

root@master:~# kubectl get pods --all-namespaces
