1.搭建openLDAP

1.1.创建命名空间

kubectl create namespace kube-ops

1.2.创建pvc

存储使用的是nfs方式挂载，storageClassName为默认，所以可写可不写。

mkdir -p ~/ldap ; cd ~/ldap
cat > pvc.yaml << EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: ldap-data-pvc
  namespace: kube-ops
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: nfs-storage
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: ldap-config-pvc
  namespace: kube-ops
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: nfs-storage
EOF
kubectl apply -f pvc.yaml

1.3.创建svc

cat > ldap-deployment.yaml <<EOF
kind: Deployment
apiVersion: apps/v1
metadata:
  name: openldap
  namespace: kube-ops
  labels:
    app: openldap
  annotations:

        - name: ldap-data-pvc
          persistentVolumeClaim:
            claimName: ldap-data-pvc
