linux 部署kubernetes
系统初始化
生产环境肯定要更高配置，虚拟机以保守的最低配置。
| 机器 | ip | 规格 |
|---|---|---|
| master | 192.168.203.11 | 1核2线程、2G内存、40G磁盘 |
| node2 | 192.168.203.12 | 1核2线程、2G内存、40G磁盘 |
| node3 | 192.168.203.13 | 1核2线程、2G内存、40G磁盘 |
修改为静态ip
vi /etc/resolv.conf

追加内容后保存并退出
nameserver 223.5.5.5
nameserver 223.6.6.6

BOOTPROTO="dhcp"改成BOOTPROTO=“static”，如果是复制的机器UUID、IPADDR也要不一致
TYPE="Ethernet" PROXY_METHOD="none" BROWSER_ONLY="no" BOOTPROTO="static" DEFROUTE="yes" IPV4_FAILURE_FATAL="no" IPV6INIT="yes" IPV6_AUTOCONF="yes" IPV6_DEFROUTE="yes" IPV6_FAILURE_FATAL="no" IPV6_ADDR_GEN_MODE="stable-privacy" NAME="ens33" UUID="0ef41c81-2fa8-405d-9ab5-3ff34ac815cf" DEVICE="ens33" ONBOOT="yes" IPADDR="192.168.203.11" PREFIX="24" GATEWAY="192.168.203.2" IPV6_PRIVACY="no"

永久设置hostname（根据机器分别设置mster、node1、node2）
三台机器分别为mster、node1、node2
sudo hostnamectl set-hostname master

使用hostnamectl或hostname命令验证是否修改成功
在hosts文件添加内容（仅master设置）
sudo cat >> /etc/hosts << EOF
192.168.203.11 master
192.168.203.12 node1

sudo yum list docker-ce.x86_64 --showduplicates | sort -r
- 1
安装指定版本的docker-ce
sudo yum -y install docker-ce-[VERSION]
sudo yum -y install docker-ce-18.06.1.ce-3.el7
- 1
启动docker服务
sudo systemctl enable docker && sudo systemctl start docker
- 1
查看docker是否启动成功【注意docker的Client和Server要一致，否则某些情况下会报错】
sudo docker --version
- 1
创建/etc/docker/daemon.json文件并设置docker仓库为aliyun仓库
sudo cat > /etc/docker/daemon.json << EOF
{
"registry-mirrors":["https://b9pmyelo.mirror.aliyuncs.com"]
}

部署Kubernetes
apiserver-advertise-address表示master主机ip
image-repository表示镜像仓库
kubernetes-version表示k8s的版本，跟上面的kubelet、kubeadm、kubectl版本一致
service-cidr表示集群内部虚拟网络，Pod统一访问入口
pod-network-cidr表示Pod网络，与下面部署的CNI网络组件yaml中保持一致
Kubernetes初始化【仅master执行，过程可能会有点久，请耐心等待命令行输出】
–v=5可加可不加，建议加，输出完整的日志，方便排查问题
kubeadm init \
--v=5 \
--apiserver-advertise-address=192.168.203.11 \
--image-repository=registry.aliyuncs.com/google_containers \
--kubernetes-version=v1.18.0 \
--service-cidr=10.96.0.0/12 \

输出以下内容表示初始化成功
Your Kubernetes control-plane has initialized successfully! To start using your cluster, you need to run the following as a regular user: mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config You should now deploy a pod network to the cluster. Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at: https://kubernetes.io/docs/concepts/cluster-administration/addons/ Then you can join any number of worker nodes by running the following on each as root: kubeadm join 192.168.203.11:6443 --token 51c0rb.ehwwxemgec75r1g6 \ --discovery-token-ca-cert-hash sha256:fad429370f462b36d2651e3e37be4d4b34e63d0378966a1532442dc3f67e41b4

根据上面的提示执行对应的To start using your cluster, you need to run the following as a regular user：命令
master节点执行，node节点不执行
kubectl get nodes查看节点信息
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
kubectl get nodes
