k8s1.12.3集群使用token访问api

1.开启相关参数

KUBE_API_ARGS="--service-node-port-range=30000-32767 --enable-swagger-ui=true --apiserver-count=3 --audit-log-maxage=30 --audit-log-maxbackup=3 --audit-log-maxsize=100 --audit-log-path=/var/log/k8s/audit.log --event-ttl=1h"

2.创建用户，给cluster—admin角色，执行（kubectl create -f “yaml文件名”）

kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  name: admin
  annotations:
    rbac.authorization.kubernetes.io/autoupdate: "true"
roleRef:
  kind: ClusterRole
  name: cluster-admin
  apiGroup: rbac.authorization.k8s.io
subjects:
- kind: ServiceAccount
  name: admin
  namespace: kube-system
---
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin
  namespace: kube-system
  labels:
    kubernetes.io/cluster-service: "true"
    addonmanager.kubernetes.io/mode: Reconcile

3.获取token

kubectl get secret -n kube-system|grep admin
kubectl describe secret “上条命令执行结果（例：ecdataapi-token-9w7zj）” -n kube-system

4. 拿到token后，postman（6.7.1）中

file>settings>General>ssl certficate verification关闭

5.获取服务地址

kubectl cluster-info

获取地址后复制地址到postman，将刚才生成的token复制到Authorization>type>bearer-Token

6.访问目标地址
