背景

因为工作需要，需要在一台新集群上部署 jenkins + k8s agent 并结合 gitlab 做一下自动流水线，最后也发部到 k8s 中。

jenkins 部署

helm 仓库

直接使用官方 helm chart 即可，首先添加 helm 仓库

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: jenkins-pv-claim
  namespace: jenkins
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: jenkins-workspace-pv-claim
  namespace: jenkins
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi

RBAC 定义（用来读取 k8s 的 secret，给动态生成的 runner pod 挂载）：

# role-jenkins-all-secrets-reader.yaml
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: jenkins-all-secrets-reader
  namespace: jenkins
rules:
- apiGroups: [""]
  resources: ["secrets"]
  verbs: ["get", "list"] # 授予 get 和 list 权限
---
# rolebinding-jenkins-all-secrets-reader.yaml
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: jenkins-default-read-all-secrets
  namespace: jenkins
subjects:
- kind: ServiceAccount
  name: default
  namespace: jenkins
roleRef:
  kind: Role
  name: jenkins-all-secrets-reader # 引用上面的 Role
  apiGroup: rbac.authorization.k8s.io

然后准备好 buildkit 的本地缓存 pvc：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: jenkins-buildkit-pv-claim
  namespace: jenkins
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 20Gi

最后创建一个 docker 认证密钥

apiVersion: v1
data:
  .dockerconfigjson: xxxxxxx

kind: Secret
metadata:
  name: docker-hub-mereith
  namespace: jenkins
type: kubernetes.io/dockerconfigjson

.dockerconfigjson 是 base64 后的，其具体格式为：

{
  "auths": {
    "https://index.docker.io/v1/": {
      "auth": "xxxxxx"
    }
  }
}

其中 auth 也是一个 base64 编码的，解码后是 username:password 格式的

然后再准备一个 k8s 集群的 config 的 secret，CD 的时候用：

apiVersion: v1
data:
  config: <base64 的 kubeconfig，可以是多上下文的>
kind: Secret
metadata:
  name: kubeconfig
  namespace: jenkins
type: Opaque

这些都准备好后，都 apply 一下让他们生效。

安装

然后开始正式安装 jenkins

apiVersion: v1
kind: Pod
metadata:
  name: kaniko
spec:
  containers:
  - name: kubectl
    image: lachlanevenson/k8s-kubectl:v1.25.4
    imagePullPolicy: "IfNotPresent"
    command:
    - cat
    tty: true
    volumeMounts:
      - name: kube-config
        mountPath: /root/.kube
        defaultMode: 0600

  - name: buildkit
    image: moby/buildkit:master
    imagePullPolicy: "IfNotPresent"
    command: ["cat"]
    tty: true
    securityContext:
      privileged: true
    volumeMounts:
      - name: buildkit-secret
        mountPath: /.docker
      - name: buildkit-cache
        mountPath: /cache
    env:
      - name: DOCKER_CONFIG
        value: /.docker
  restartPolicy: Never
  volumes:
    - name: buildkit-secret
      secret:
        secretName: docker-hub-mereith
        items:
          - key: .dockerconfigjson
            path: config.json
    - name: kaniko-cache
      persistentVolumeClaim:
        claimName: jenkins-buildkit-pv-claim
    - name: kube-config
      secret:
        secretName: kubeconfig
        items:
          - key: config
            path: config

这个 Raw YAML for the Pod 会合并到默认的模版中，我们添加的文件，会增加两个容器，一个打包用的，一个是发不到 k8s 中。

添加 git 认证密钥

找到 系统管理 -> 凭据管理 -> System -> 全局凭据 -> 添加：

加一个 gitlab api token，去 gitlab 个人账号创建就行。
加一个 username and password，用来认证 git 仓库，当然你用 ssh 也行。

设置 gitlab 插件

找到 系统管理 -> 系统配置 -> GitLab：

添加一个 Connection，密钥就用刚才创建的凭据。

关闭 Crumb 保护

找到 系统管理 -> 脚本命令行:

运行 hudson.security.csrf.GlobalCrumbIssuerConfiguration.DISABLE_CSRF_PROTECTION = true
关闭同理。
不关也行，按需调整。

流水线配置

新增一个 pipeline 类型的流水线，设置中的 触发器 选 Gitlab，然后按需设置，最后展开 Advanced，生成一个 secret，最上面有一个 webhook 地址。
去 gitlab 项目中的 webhook 设置里添加一个，地址和 secret 都用这个就行。

另外 gitlab 插件默认注入了一些环境变量可以用：

pipeline {
    agent {
        kubernetes {
            inheritFrom 'default' // 确保 'default' Pod 模板存在且包含 'kaniko' (和 'kubectl') 容器
        }
    }
    
    options {
        ansiColor('xterm')
        timeout(time: 20, unit: 'MINUTES') // 全局超时设置
    }

    // --- 参数优化 ---
    // 只定义一个手动触发所需的分支参数
    parameters {
        string(name: 'BRANCH_TO_BUILD', defaultValue: '0414', description: '要构建和部署的 Git 分支')
    }

    environment {
        REGISTRY = "mereith/test"
        IMAGE_NAME = "test"

        BUILD_START_TIME = "${System.currentTimeMillis()}" // 记录构建开始时间
