容器编排(学习环境 k8s)安装kind

1.kind官网：kind
2.安装kubectl,参考:k8s集群安装及相关问题解决
3.依据官网引导，安装kind

curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.11.1/kind-linux-amd64
chmod +x ./kind
#移动kind至自己的目录，最好新建一个
mv ~/kind /data/kindk8s/
#创建默认集群
./kind create cluster
#下载kind镜像并创建完成后，查看创建的集群
kubectl cluster-info --context kind-kind
#查看节点信息
kubectl get nodes

4.以上是简单的安装，下面开始在kind中安装dashboard的方法
删除已安装的cluster
./kind delete cluster --name kind
在创建集群时指定暴露的端口，等下把dashboard的端口暴露到指定端口去
kind-example-config.yaml

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
networking:
  # WARNING: It is _strongly_ recommended that you keep this the default
  # (127.0.0.1) for security reasons. However it is possible to change this.
  apiServerAddress: "0.0.0.0"
  # By default the API server listens on a random open port.
  # You may choose a specific port but probably don't need to in most cases.
  # Using a random port makes it easier to spin up multiple clusters.
  apiServerPort: 6443
nodes:
  - role: control-plane
    extraPortMappings:
    - containerPort: 30001
      hostPort: 30001
      listenAddress: "0.0.0.0"
      protocol: tcp
    - containerPort: 30002
      hostPort: 30002
      listenAddress: "0.0.0.0"
      protocol: tcp
    - containerPort: 30003
      hostPort: 30003
      listenAddress: "0.0.0.0"
      protocol: tcp
    - containerPort: 30004
      hostPort: 30004
      listenAddress: "0.0.0.0"
      protocol: tcp
    - containerPort: 30005
      hostPort: 30005
      listenAddress: "0.0.0.0"
      protocol: tcp

# 创建集群，不指定集群名称默认为kind
./kind create cluster --config kind-example-config.yaml --name mycluster

5.下载dashboard
dashboardgit
根据k8s版本选择要下载的yaml

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.3.1/aio/deploy/recommended.yaml

修改vi recommended.yaml

---

kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
spec:
  type: NodePort  # 新添加
  ports:
    - port: 443
      targetPort: 8443
      nodePort: 30001 #新添加
  selector:
    k8s-app: kubernetes-dashboard

修改成功后部署：kubectl apply -f recommended.yaml
查看deployment状态：
kubectl get deployments -n kubernetes-dashboard
6.生成token
参考链接：生成token参考
整合后的dashboard-acount.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kubernetes-dashboard

创建账号与授权：
kubectl apply -f dashboard-acount.yaml
查看token

kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath="{.secrets[0].name}") -o go-template="{{.data.token | base64decode}}"

创建授权账号成功后查看token方式2

 kubectl get secrets -n kubernetes-dashboard |grep admin-user
 kubectl describe secrets admin-user-token-sqpw9 -n kubernetes-dashboard

dashboard使用官方文档：https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/
