glusterfsファイルシステムを使ってk 8 sの耐久化メモリを作ります.

glusterfsのインストールを参照してください.https://jimmysong.io/kubernetes-handbook/practice/using-glusterfs-for-persistent-storage.html
一、次のスクリプトを使ってデータボリュームを作成します.

#!/bin/bash

if [ $# -lt 3 ];
then
    echo "please input at least 3 param"
    exit 0
fi
volumeName=$1
mountPath=$2
dbSize=$3
gluster volume create $volumeName  replica 2 transport tcp gfs-node1:/data1/gfs_data/${mountPath} gfs-node2:/data1/gfs_data/${mountPath} gfs-node3:/data1/gfs_data/${mountPath} gfs-node4:/data1/gfs_data/
${mountPath} force
gluster volume list
gluster volume start $volumeName
#gluster volume quota $volumeName enable
#gluster volume quota $volumeName limit-usage / ${dbSize}GB
#gluster volume set $volumeName performance.cache-size 2GB
#gluster volume set $volumeName performance.io-thread-count 16
#gluster volume set $volumeName network.ping-timeout 10
#gluster volume set $volumeName performance.write-behind-window-size 1024MB
echo "#########volume list #########"
gluster volume list

二、endpointsの配置

{
  "kind": "Endpoints",
  "apiVersion": "v1",
  "metadata": {
    "name": "glusterfs-cluster",
    "namespace": "ci"
  },
  "subsets": [
    {
      "addresses": [
        {
          "ip": "192.168.1.1"
        }
      ],
      "ports": [
        {
          "port": 1990
        }
      ]
    },
    {
      "addresses": [
        {
          "ip": "192.168.1.2"
        }
      ],
      "ports": [
        {
          "port": 1990
        }
      ]
    },
    {
      "addresses": [
        {
          "ip": "192.168.1.3"
        }
      ],
      "ports": [
        {
          "port": 1990
        }
      ]
    },
    {
      "addresses": [
        {
          "ip": "192.168.1.4"
        }
      ],
      "ports": [
        {
          "port": 1990
        }
      ]
    }
  ]
}

皰kubectl apply-f glusterfs-endpoints.json
endpoints serviceの設定

{
  "kind": "Service",
  "apiVersion": "v1",
  "metadata": {
    "name": "glusterfs-cluster",
    "namespace": "ci"
  },
  "spec": {
    "ports": [
      {"port": 1990}
    ]
  }
}

菵 kubectl appy-f glusterfs-service.json
三、pvを作成する
kubectl create-f jecins-master-pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv-jenkins-master
  namespace: ci
spec:
  capacity:
    storage: 20Gi
  accessModes:
    - ReadWriteMany
  glusterfs:
    endpoints: "glusterfs-cluster"
    path: "k8s-volume-jenkins-master"
    readOnly: false

四、pvcを作成する
同前 kubectl create-f jecins-master-pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-jenkins-master
  namespace: ci
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 20Gi

五、k 8 sオブジェクトはpvcを使用する.

          volumeMounts:
            - name: home
              mountPath: "/var/jenkins_home"
      volumes:
        - name: home
          persistentVolumeClaim:
            claimName: pvc-jenkins-master
