17. 部署jenkins持续集成工具

# helm安装jenkins

添加repo
```
helm repo add jenkins https://charts.jenkins.io
helm repo update
```

搜索repo
```
helm search repo jenkins/jenkins
```

下载离线chart包
```
cd /root/helm
helm pull jenkins/jenkins --untar
```

修改valume配置

```
namespaceOverride: jenkins # 指定运行命名空间
controller:
  admin:
    username: "admin"
    password: "admin" # 指定用户名密码，默认随机生成
  javaOpts: "-Duser.timezone=Asia/Shanghai" # 找到javaOpts配置项并指定时区
  jenkinsOpts: "-Dorg.apache.commons.jelly.tags.fmt.timeZone=Asia/Shanghai" # 指定时区
  ingress:
    enabled: true # 开启并使用ingress访问
    ingressClassName: nginx # 指定ingress使用nginx类
    hostName: jenkins.local.com # 指定访问域名
persistence:
  enabled: true
  existingClaim: jenkins # 指定已创建的PVC名称
```

创建指定的命名空间

```
kubectl create ns jenkins
```

创建PV和PVC供jenkins使用

>注意⚠️：创建PV涉及到的NFS存储及StorageClass此处不做说明
如需配置请参考 [<部署NFS文件存储>](/doc/478/ "部署NFS文件存储")

```
tee > jenkins/persistentVolumeClaim-Jenkins.yaml <<EOF
apiVersion: v1
kind: PersistentVolume
metadata:
  name: pvc-jenkins
  namespace: jenkins # 指定命名空间
spec:
  capacity:
    storage: 50Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteOnce
  persistentVolumeReclaimPolicy: Retain
  storageClassName: nfs-storage
  nfs:
    server: 192.168.88.62
    path: /data/nfs/jenkins-storage
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: jenkins
  namespace: jenkins # 存储卷PVC名称，对应values.yaml中的existingClaim值
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 50Gi
  storageClassName: nfs-storage
EOF
```

应用并创建PVC
```
kubectl apply -f jenkins/persistentVolumeClaim-Jenkins.yaml
```

离线安装Jenkins

```
helm install jenkins jenkins/ -f jenkins/values.yaml
```
