Kubernetes学习笔记（二十二）：Authentication 身份认证

kubectl create serviceaccount sa1

kubectl get serviceaccount

验证方式kube-apiserver：

• Static Password File
• Static Token File
• Certificates
• Identity Services，第三方身份验证协议，如LDAP、Kerberos等

Static Password File ：

user-details.csv :

password,username,userid(,groupname optional)
...

user-token-details.csv

token,username,userid(,groupname optional)
...

定义方式：

• --basic-auth-file=user-details.csv --token-auth-file=user-details.csv apiserver重启才能生效

• kubeadm /etc/kubernetes/manifests/kube-apiserver.yaml

  apiVersion: v1
  kind: Pod
  metadata:
    creationTimestamp: null
    name: kube-apiserver
    namespace: kube-system
  spec:
    containers:
    - command:
      - kube-apiserver
      - --authorization-mode=Node,RBAC
      - --advertise-address=172.17.0.107
      - --allow-privileged=true
      - --enable-admission-plugins=NodeRestriction
      - --enable-bootstrap-token-auth=true
      image: k8s.gcr.io/kube-apiserver-amd64:v1.11.3
      name: kube-apiserver
  

访问：

• curl -v -k https://master-node-ip:6443/api/v1/pods -u "username:password" {data...}

• curl -v -k <link> --header "Authorization: Bearer xxxxxxxx"

注意点：

• 不推荐使用静态储存（在v1.19已弃用）
• Consider volume mount while providing the auth file in a kubeadm setup
• Setup Role Based Authorization for the new users
