部署完K8sWeb UI后，在Web上部署Pod、Service、RS、RC等资源报错

**报错信息：** `pods is forbidden: User "system:serviceaccount:kube-system:namespace-controller" cannot create resource "pods" in API group "" in the namespace "default"`

**问题分析：** API组中用户不能在默认命名空间创建Pod，也就是说使用原token认证登录的用户是无权操作

**解决方案：**

1.创建kubernetes-dashboard管理员角色

[root@k8s-master ~]# vi k8s-admin.yaml
    apiVersion: v1
    kind: ServiceAccount
    metadata:
      name: dashboard-admin
      namespace: kube-system
    ---
    kind: ClusterRoleBinding
    apiVersion: rbac.authorization.k8s.io/v1beta1
    metadata:
      name: dashboard-admin
    subjects:
      - kind: ServiceAccount
        name: dashboard-admin
        namespace: kube-system
    roleRef:
      kind: ClusterRole
      name: cluster-admin
      apiGroup: rbac.authorization.k8s.io
    
    [root@k8s-master ~]# kubectl create -f k8s-admin.yaml

2.获取dashboard管理员角色token

[root@k8s-master ~]# kubectl describe secret dashboard-admin-token-7z6zm -n kube-system 
    Name:         dashboard-admin-token-7z6zm
    Namespace:    kube-system
    Labels:       <none>
    Annotations:  kubernetes.io/service-account.name: dashboard-admin
                  kubernetes.io/service-account.uid: f0d1d33f-d43d-11e9-a75a-fa163e7d0486
    
    Type:  kubernetes.io/service-account-token
    
    Data
    ====
    token:      eyJhbGciOiJSUzI1NiIsImtpZCI6IiJ9.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.Jmws1PEvnjG4fmR2YoZTV909dvPwJdRTi_KSkUnezA1i1GBd7YHpIjw_MmVj8Vx-C4dE83OPPqS2UIdslJQV-KsAYQNOMaPxhxOz4WRgIzEcxpOXMEKny93AGB6PcpQrmtNnmnwGEX8wF-dqogqoyH-8X-iDdpQ75-TbrVmco-NZtb7GMGKiTnBK_cRZ2iGg-Oq4ic7YoJpM0C1a87xNb4kOfUCIShj1JqWJTdoMtvjiCSTvjBVz8mICvQ9qMrJfxCZZJ6BjNNvMDqrd2cWKu14mjDo_hipt6DBcKSZDmp-jBCccx4RG_9CGpp6UyeFWVuEvDxeN8ABkX6RB74s3hw

3.使用第二步第12行的token登陆kubernetes-dashboard web界面即可
