如何在阿里雲容器服務ACK上部署應用管理/釋出系統Spinnaker

Spinnaker是一個開源的多雲持續交付平臺,可幫助您方便管理應用以及快速交付應用。

Spinnaker的兩個主要功能是: 應用管理 , 應用交付

Applications, clusters, and server groups是Spinnaker中非常重要的幾個概念, Load balancers and firewalls描述瞭如何向用戶公開你的服務:

在ACK上部署Spinnaker的步驟:
(1)建立一個ACK叢集
(2)建立Spinnaker需要的Kubernetes資源
(3)配置Spinnaker的安裝檔案
(4)部署並訪問Spinnaker

1. 建立叢集

參考 建立阿里雲容器服務ACK叢集

2. 建立Spinnaker需要的Kubernetes資源

2.1 建立 Namespace

$ kubectl create ns spinnaker

2.2 建立ServiceAccount ClusterRoleBinding 資源用於 Halyard 部署 Spinnaker

rbac.yaml 檔案內容:

apiVersion: v1
kind: ServiceAccount
metadata:
  name: spinnaker-service-account
  namespace: spinnaker
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: spinnaker-role-binding
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- namespace: spinnaker
  kind: ServiceAccount
  name: spinnaker-service-account

執行以下命令建立資源:

$ kubectl create -f rbac.yaml

3. 配置Spinnaker的安裝檔案

Spinnaker是通過Halyard工具來管理配置和部署的。

3.1 部署halyard

hal-deployment.yaml 檔案內容如下:

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  labels:
    app: hal
  name: hal
  namespace: spinnaker
spec:
  replicas: 1
  selector:
    matchLabels:
      app: hal
  template:
    metadata:
      labels:
        app: hal
    spec:
      containers:
      - image: registry.cn-hangzhou.aliyuncs.com/haoshuwei24/halyard:stable
        name: halyard
      serviceAccount: spinnaker-service-account
      serviceAccountName: spinnaker-service-account

執行以下命令建立資源:

$ kubectl create -f hal-deployment.yaml

檢視pod是否正常執行:

$ kubectl -n spinnaker get po
NAME                   READY   STATUS    RESTARTS   AGE
hal-77b4cf787f-p25h5   1/1     Running   0          9m54s

3.2 配置Cloud Provider

  • exec進入hal pod:
$ kubectl -n spinnaker exec -it hal-77b4cf787f-p25h5 bash
  • 拷貝kubeconfig檔案為~/.kube/config
  • 啟用kubernetes provider:
$ hal config provider kubernetes enable
+ Get current deployment
  Success
+ Edit the kubernetes provider
  Success
Problems in default.provider.kubernetes:
- WARNING Provider kubernetes is enabled, but no accounts have been
  configured.

+ Successfully enabled kubernetes
  • 新增一個spinnaker account:
$ CONTEXT=$(kubectl config current-context)

$ hal config provider kubernetes account add my-k8s-v2-account \
    --provider-version v2 \
    --context $CONTEXT
+ Get current deployment
  Success
+ Add the my-k8s-v2-account account
  Success
+ Successfully added account my-k8s-v2-account for provider
  kubernetes.
$ hal config features edit --artifacts true
+ Get current deployment
  Success
+ Get features
  Success
+ Edit features
  Success
+ Successfully updated features.

3.3 選擇Spinnaker的部署環境

執行以下命令:

$ ACCOUNT=my-k8s-v2-account
$ hal config deploy edit --type distributed --account-name $ACCOUNT
+ Get current deployment
  Success
+ Get the deployment environment
  Success
+ Edit the deployment environment
  Success
+ Successfully updated your deployment environment.

3.4 配置儲存

Spinnaker需要外部安全可靠的儲存服務來保留您的應用程式設定和已配置的Pipeline。由於這些資料很敏感,丟失的話恢復起來代價很高。 本次示例我們臨時搭建一個Minio Service

  • 部署Minio
    minio-deployment.yml檔案內容如下:
---
apiVersion: v1
kind: Namespace
metadata:
  name: minio

---
apiVersion: apps/v1beta1
kind: Deployment
metadata:
  namespace: minio
  name: minio
  labels:
    component: minio
spec:
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        component: minio
    spec:
      volumes:
      - name: storage
        emptyDir: {}
      - name: config
        emptyDir: {}
      containers:
      - name: minio
        image: minio/minio:latest
        imagePullPolicy: IfNotPresent
        args:
        - server
        - /storage
        - --config-dir=/config
        env:
        - name: MINIO_ACCESS_KEY
          value: "<your MINIO_ACCESS_KEY>"
        - name: MINIO_SECRET_KEY
          value: "your MINIO_SECRET_KEY"
        ports:
        - containerPort: 9000
        volumeMounts:
        - name: storage
          mountPath: "/storage"
        - name: config
          mountPath: "/config"

---
apiVersion: v1
kind: Service
metadata:
  namespace: minio
  name: minio
  labels:
    component: minio
spec:
  # ClusterIP is recommended for production environments.
  # Change to NodePort if needed per documentation,
  # but only if you run Minio in a test/trial environment, for example with Minikube.
  type: LoadBalancer
  ports:
    - port: 9000
      targetPort: 9000
      protocol: TCP
  selector:
    component: minio

設定MINIO_ACCESS_KEY MINIO_SECRET_KEY的值並部署Minio:

$ kubectl create -f minio-deployment.yaml

檢視Pod執行狀態和服務埠:

$ kubectl -n minio get po
NAME                     READY   STATUS    RESTARTS   AGE
minio-59fd966974-nn5ns   1/1     Running   0          12m
[root@iZbp184d18xuqpwxs9tat3Z minio]# kubectl -n minio get svc
NAME    TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)          AGE
minio   LoadBalancer   172.27.12.130   xxx.xx.xxx.xx   9000:30771/TCP   12m

建立job在Minio中建立bucket和path:
job.yaml內容如下:

apiVersion: batch/v1
kind: Job
metadata:
  namespace: minio
  name: minio-setup
  labels:
    component: minio
spec:
  template:
    metadata:
      name: minio-setup
    spec:
      restartPolicy: OnFailure
      volumes:
      - name: config
        emptyDir: {}
      containers:
      - name: mc
        image: minio/mc:latest
        imagePullPolicy: IfNotPresent
        command:
        - /bin/sh
        - -c
        - "mc --config-dir=/config config host add spinnaker http://xxx.xx.xxx.xx:9000 MINIO_ACCESS_KEY MINIO_SECRET_KEY && mc --config-dir=/config mb -p spinnaker/spinnaker"
        volumeMounts:
        - name: config
          mountPath: "/config"

你需要記錄 ENDPOINT  MINIO_ACCESS_KEY MINIO_SECRET_KEY 在下文會用到

  • 編輯和配置儲存資訊
    在hal pod中繼續執行以下步驟:
$ mkdir -p ~/.hal/default/profiles
$ echo "spinnaker.s3.versioning: false" >> ~/.hal/default/profiles/front50-local.yml
$ ENDPOINT=http://xxx.xx.xxx.xx:9000
$ MINIO_ACCESS_KEY=<your key>
$ MINIO_SECRET_KEY=<your secret>
$ echo $MINIO_SECRET_KEY | hal config storage s3 edit --endpoint $ENDPOINT \
    --path-style-access true \
    --bucket spinnaker \
    --root-folder spinnaker \
    --access-key-id $MINIO_ACCESS_KEY \
    --secret-access-key
+ Get current deployment
  Success
+ Get persistent store
  Success
+ Edit persistent store
  Success
+ Successfully edited persistent store "s3".

$ hal config storage edit --type s3
+ Get current deployment
  Success
+ Get persistent storage settings
  Success
+ Edit persistent storage settings
  Success
+ Successfully edited persistent storage.

4. 部署Spinnaker並訪問服務

  • 列出並選擇一個版本 注意:此處會從Google Cloud上獲取一個versions.yml檔案, 請自行解決網路問題
$ hal version list
+ Get current deployment
  Success
+ Get Spinnaker version
  Success
+ Get released versions
  Success
+ You are on version "", and the following are available:

   (Requires Halyard >= 1.17)
  • 選擇1.16.1版本:
$ hal config version edit --version 1.16.1
+ Get current deployment
  Success
+ Edit Spinnaker version
  Success
+ Spinnaker has been configured to update/install version "1.16.1".
  Deploy this version of Spinnaker with `hal deploy apply`.
  • 部署Spinnaker
$ hal deploy apply
+ Get current deployment
  Success
+ Prep deployment
  Success
Problems in default.security:
- WARNING Your UI or API domain does not have override base URLs
  set even though your Spinnaker deployment is a Distributed deployment on a
  remote cloud provider. As a result, you will need to open SSH tunnels against
  that deployment to access Spinnaker.
? We recommend that you instead configure an authentication
  mechanism (OAuth2, SAML2, or x509) to make it easier to access Spinnaker
  securely, and then register the intended Domain and IP addresses that your
  publicly facing services will be using.

  • 訪問Spinnaker服務
    kubectl -n spinnaker edit svc spin-deck修改提供ui服務的 spin-deck service資源 type: LoadBalancer
$ kubectl -n spinnaker get svc |grep spin-deck
spin-deck          LoadBalancer   172.21.6.203    xxx.xx.xx.xx   9000:30680/TCP   16m
  • 在hal pod中配置ui可外部訪問
$ hal config security ui edit --override-base-url http://xxx.xx.xx.xx:9000
+ Get current deployment
  Success
+ Get UI security settings
  Success
+ Edit UI security settings

  that deployment to access Spinnaker.

+ Successfully updated UI security settings.

在瀏覽器中訪問Spinnaker ui介面 http://xxx.xx.xx.xx:9000

注意: Spinnaker本身並沒有使用者管理模組, 在生產中使用的話,使用者需要對接自己的認證系統, 參考[Spinnaker Authentication](https://www.spinnaker.io/setup/security/authentication/)

  • 若需要外部訪問Spinnaker API, 則需要做以下操作
    修改 Service spin-gate 為 type: LoadBalancer

設定api為外部可訪問:

$ hal config security api edit --override-base-url http://xx.xx.xxx.xx:8084
+ Get current deployment
  Success
+ Get API security settings
  Success
+ Edit API security settings
  Success
