VMware Fusion部署 k8s cluster集群

导入ubuntu 镜像，Ubuntu 22.04 LTS iso https://ubuntu.com/download/desktop/thank-you?version=22.04&architecture=amd64

设置 proxy, 因为之后要用google.
alias curl=“curl -x *****😗***”
vim /etc/apt/apt.conf.d/80proxy

Acquire::http::proxy "http://****";
Acquire::https::proxy "http://*****";

sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates curl

sudo curl -fsSLo /usr/share/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg

echo “deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main” | sudo tee /etc/apt/sources.list.d/kubernetes.list

sudo apt-get update
sudo apt-get install -qy kubeadm=1.22.3-00 kubelet=1.22.3-00 kubectl=1.22.3-00
sudo apt-mark hold kubelet kubeadm kubectl

保存当前虚机设置，拷贝出另外两个虚机，node-1,node-2

查看本地fushion 的nat 配置
cd /Library/Preferences/VMware Fusion

cat vmnet8/nat.conf

结果是
ip = 192.168.187.2
netmask = 255.255.255.0

打开虚机master,node-1,node-2.
配置ipv地址。
三个虚机的address需要不同，其他设为一样。

修改node-1和node-2的hostname

sudo su
vim /etc/hostname
改为node-1, node-2

重启三台虚机，使配置生效。

在master的虚机上执行
kubeadm init --apiserver-advertise-address 192.168.187.200 --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.22.3 --pod-network-cidr 10.244.0.0/16
结果如下： 拷贝join这条语句

export KUBECONFIG=/etc/kubernetes/admin.conf

kubectl get pod --namespace=kube-system

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

kubectl get pod

分别切换到node-1, node-2

执行
sudo su
kubeadm join 192.168.187.200:6443 --token lalblo.ojd7xx6byohtxjr7
–discovery-token-ca-cert-hash sha256:2260781ac868d2dfcf296ef77daba74716ee254c6da48fd2507f0b7de7b4aa23

然后到master上再次执行 kubectl get node.可以看到多了结点。

到此就部署成功了
