TKG Cluster获取永不过期Token
登录TKC集群
$ kubectl vsphere login --server=192.168.203.194 \
--tanzu-kubernetes-cluster-name tkc-dev-cluster \
--tanzu-kubernetes-cluster-namespace tkc-01 \
--vsphere-username administrator@vsphere.local \
--insecure-skip-tls-verify
生成管理员服务帐户并创建群集角色绑定
$ kubectl create serviceaccount napp-admin -n kube-system
$ kubectl create clusterrolebinding napp-admin --serviceaccount=kube-system:napp-admin --clusterrole=cluster-admin
手动创建管理员服务帐户的身份验证令牌
- 创建napp-admin.yaml
apiVersion: v1
kind: Secret
type: kubernetes.io/service-account-token
metadata:
name: napp-admin
namespace: kube-system
annotations:
kubernetes.io/service-account.name: "napp-admin"
- 应用napp-admin.yaml文件
$ kubectl apply -f napp-admin.yaml
获取管理员服务帐户和群集证书颁发机构的身份验证令牌
$ SECRET=$(kubectl get secrets napp-admin -n kube-system -ojsonpath='{.metadata.name}')
$ TOKEN=$(kubectl get secret $SECRET -n kube-system -ojsonpath='{.data.token}' | base64 -d)
$ kubectl get secrets $SECRET -n kube-system -o jsonpath='{.data.ca\.crt}' | base64 -d > ./ca.crt
获取主管URL上的TKG集群
$ CONTEXT=$(kubectl config view -o jsonpath='{.current-context}')
$ CLUSTER=$(kubectl config view -o jsonpath='{.contexts[?(@.name == "'"$CONTEXT"'")].context.cluster}')
$ URL=$(kubectl config view -o jsonpath='{.clusters[?(@.name == "'"$CLUSTER"'")].cluster.server}')
为TKG集群生成具有未过期令牌的配置文件
$ TO_BE_CREATED_KUBECONFIG_FILE="kubeconfig.conf"
$ kubectl config --kubeconfig=$TO_BE_CREATED_KUBECONFIG_FILE set-cluster $CLUSTER --server=$URL --certificate-authority=./ca.crt --embed-certs=true
$ kubectl config --kubeconfig=$TO_BE_CREATED_KUBECONFIG_FILE set-credentials napp-admin --token=$TOKEN
$ kubectl config --kubeconfig=$TO_BE_CREATED_KUBECONFIG_FILE set-context $CONTEXT --cluster=$CLUSTER --user=napp-admin
$ kubectl config --kubeconfig=$TO_BE_CREATED_KUBECONFIG_FILE use-context $CONTEXT
查看最后生成的文件
令牌文件可以在任何地方进行调用，且永不过期
