Kubernetes - - k8s - v1.12.3 OpenLDAP统一认证

1，基本概念

为了方便管理和集成jenkins，k8s、harbor、jenkins均使用openLDAP统一认证。

2，部署openLDAP

根据之前的文档，openLDAP使用GFS进行数据持久化。
下载对应的openLDAP文件

git clone https://github.com/xiaoqshuo/k8s-cluster.git

2.1 创建openLDAP

[root@k8s-master01 k8s-cluster]# kubectl apply -f openldap/
deployment.extensions/ldap created
persistentvolumeclaim/openldap-data created
secret/ldap-secret created
service/ldap-service created
deployment.extensions/phpldapadmin created
service/phpldapadmin created

此处参考的是：https://github.com/osixia/docker-openldap，更新DN可以更改environment下的yaml文件，默认的example.org

2.2 创建ldap-ui-ingress

[root@k8s-master01 openldap]# kubectl create -f traefik-ldap.yaml 
ingress.extensions/ldap-ui created

[root@k8s-master01 openldap]# cat traefik-ldap.yaml 
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ldap-ui
  namespace: public-service
  annotations:
    kubernetes.io/ingress.class: traefik
spec:
  rules:
  - host: ldap.k8s.net
    http:
      paths:
      - backend:
          serviceName: phpldapadmin
          servicePort: 8080

3，查看验证

[root@k8s-master01 openldap]# kubectl get po,svc,pvc -n public-service | grep ldap
