添加github application

打开 https://github.com/settings/developers 新建一个 authapp，并记录client_id,和 client_secret 回调地址填写 http://edrone.ismewen.com/login。

helm安装drone

添加helm仓库

helm repo add stable  http://mirror.azure.cn/kubernetes/charts/

安装helm

kubectl create ns edrone
helm install edrone stable/drone -n edrone -f values.yaml

values.yaml

ingress:
  enabled: true
  annotations:
    kubernetes.io/ingress.class: nginx
    cert-manager.io/cluster-issuer: letsencrypt-staging
  hosts:
    - edrone.ismewen.com
sourceControl:
  provider: github
  github:
    clientID: YOUR_CLIENT_ID 
    clientSecretKey: clientSecret
    clientSecretValue: YOUR_CLIENT_SECRET_VALUE 
    server: https://github.com

server:
  adminUser: ismewen # githubname
  kubernetes:
    enabled: true
  host: edrone.ismewen.com
  protocol: http

persistence:
  enabled: true
  existingClaim: dronepvc # 预先创建一个pvc

验证安装结果

drone server pod running

root@CCS-TEST-M001:~/ethan/edrone# kubectl get pods -n edrone
NAME                                   READY   STATUS    RESTARTS   AGE
edrone-drone-server-6b49c69997-qzpg6   1/1     Running   0          11h

edrone.ismewen.com 能够正常访问

drone部署helm应用

准备部署的应用

新建一个django应用并为其编写Dockerfile 和 helm charts包. 具体位置在 https://github.com/ismewen/edrone.

drone上面激活

激活drone并设置为trust

获取k8s信息

获取k8s相关信息. 并在drone中添加secret信息.

获取token

kubectl get secret -n kube-system | grep admin-user | awk '{print $1}' | xargs -I  {} kubectl get secret {} -o jsonpath={.data.token} -n kube-system | base64 -d

获取 ca

kubectl get secret -n kube-system | grep admin-user | awk '{print $1}' | xargs -I  {} kubectl get secret {} -o jsonpath={.data.ca\\.crt} -n kube-system

添加 k8s_token, k8s_ca, k8s_api_server等secret

编写 .drone.yaml

kind: pipeline
name: default

steps:
  - name: docker
    image: plugins/docker
    settings:
      repo: fscripy/edrone
      tag: ${DRONE_COMMIT_SHA}
      username:
        from_secret: fscripyu_username
      password:
        from_secret: fscripyu_password
    volumes:
      - name: dockercache
        path: /var/lib/docker
  - name: default-deploy
    image: bitsbeats/drone-helm3
    settings:
      kube_api_server:
        from_secret: k8s_api_server
      kube_token:
        from_secret: k8s_token
      kube_certificate:
        from_secret: k8s_ca
      chart: ./edrone
      release: edrone
      helm_command: upgrade
      wait: true
      force: false
      namespace: default
      values: image.tag=${DRONE_COMMIT_SHA}
volumes:
- name: dockercache
  host:
    path: /tmp/docker/${DRONE_REPO}/${DRONE_BRANCH}

至此一个完整的部署流程就走完了。

DRONE_YAML_ENDPOINT 自定义yaml返回

修改drone server

修改drone server的部署方式。环境变量新增 `DRONE_YAML_ENDPOINT``

server:
  adminUser: ismewen
  kubernetes:
    enabled: true
  host: edrone.ismewen.com
  protocol: http
  env:
    DRONE_YAML_ENDPOINT: http://edrone-demo.ismewen.com/edrone/

升级一下drone server. helm upgrade edrone stable/drone -n edrone -f values.yaml

DRONE_YAML_ENDPOINT的作用

drone每次构建的时候会向 DRONE_YAML_ENDPOINT 定义的地址发送一个post请求，并获取构建的yaml.所以我们定义的接口需要返回构建所需的yaml。

dronepost的提交的相关数据如下

headers(这里有个坑， headers中的accept为 application/vnd.drone.config.v1+json。解决办法可以参考EdronAPIView)

{
	'Content-Length': '1193',
	'Content-Type': 'application/json',
	'Host': 'edrone-demo.ismewen.com',
	'X-Request-Id': 'f0b7add0ee3094ea3fd634629bda0725',
	'X-Real-Ip': '10.244.3.1',
	'X-Forwarded-For': '10.244.3.1',
	'X-Forwarded-Host': 'edrone-demo.ismewen.com',

	'X-Original-Uri': '/edrone/',
	'X-Scheme': 'http',

	'Digest': 'SHA-256=Dtn2RSEVorWlBinp4/XzpMseS/UvYK/sQjbMfJPYhfs=',
	'Signature': 'keyId="hmac-key",
	algorithm="hmac-sha256",
	signature="VBrMY7bohxd5rxAHeclFA9WM8Wshcy1YBx5StGCNSvQ=",
	headers="accept accept-encoding content-type date digest"'
}

}

查找所需要的drone文件

根据项目的名字和分支的名字找到对应的yaml返回给drone server。返回的数据格式如下。

{
    "Data": .... # yaml字符串
}

projects
├── __init__.py
├── default.yaml
└── edrone
    ├── __init__.py
    ├── default.yaml
    ├── develop.yaml
    └── master.yaml

这样便能将所有的项目的yaml文件集中管理起来。解决了前面提的问题1.

手动触发构建

参考dron的官方的api https://docs.drone.io/api/builds/build_create/ 便可实现手动触发一次构建。

设置drone server的数据库

server:
  adminUser: ismewen
  kubernetes:
    enabled: true
  host: edrone.ismewen.com
  protocol: http
  env:
    DRONE_YAML_ENDPOINT: http://edrone-demo.ismewen.com/edrone/
  database:
    driver: postgres
    dataSource: postgres://xxx:xxx@postgresql-13293-0.cloudclusters.net:13314/edrone

再helm upgrade一下.

建立django模型

执行 inspect 命令.生成django的model

python manage.py inspectdb

结合api编写接口

详细代码请参考 BuildAPIViewSet类的实现

class BuildAPIViewSet(APIViewSet):
    custom_name = "build"
    path = "builds"

    model = Builds
    serializer_class = serializers.BuildSerializer

    serializer_mapping = {
        "create": serializers.BuildCreateSerializer
    }

通过django的model和drone的api相结合便能比较好的实现drone自带的界面。方便集成到其他的系统。至此便解决了问题2.
