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。html

Spinnaker的兩個主要功能是： 應用管理 , 應用交付git

Applications, clusters, and server groups是Spinnaker中很是重要的幾個概念， 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集羣
（2）建立Spinnaker須要的Kubernetes資源
（3）配置Spinnaker的安裝文件
（4）部署並訪問Spinnakerapi

1. 建立集羣

參考 建立阿里雲容器服務ACK集羣瀏覽器

2. 建立Spinnaker須要的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 文件內容：安全

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

運行如下命令建立資源：bash

$ kubectl create -f rbac.yaml

3. 配置Spinnaker的安裝文件

Spinnaker是經過Halyard工具來管理配置和部署的。網絡

3.1 部署halyard

hal-deployment.yaml 文件內容以下：session

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

運行如下命令建立資源：

$ kubectl create -f hal-deployment.yaml

查看pod是否正常運行：

$ 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文件爲~/.kube/config
  • 啓用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
  • 添加一個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

運行如下命令：

$ 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 配置存儲

Spinnaker須要外部安全可靠的存儲服務來保留您的應用程序設置和已配置的Pipeline。因爲這些數據很敏感，丟失的話恢復起來代價很高。 本次示例咱們臨時搭建一個Minio Service

  • 部署Minio
    minio-deployment.yml文件內容以下：
---
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

設置MINIO_ACCESS_KEY MINIO_SECRET_KEY的值並部署Minio：

$ kubectl create -f minio-deployment.yaml

查看Pod運行狀態和服務端口：

$ 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內容以下：

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"

你須要記錄 ENDPOINT  MINIO_ACCESS_KEY MINIO_SECRET_KEY 在下文會用到

  • 編輯和配置存儲信息
    在hal pod中繼續執行如下步驟：
$ 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文件， 請自行解決網絡問題
$ 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

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.

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
  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

注意： Spinnaker自己並無用戶管理模塊， 在生產中使用的話，用戶須要對接本身的認證系統， 參考[Spinnaker Authentication](https://www.spinnaker.io/setup/security/authentication/)

  • 若須要外部訪問Spinnaker API， 則須要作如下操做
    修改 Service spin-gate 爲 type: LoadBalancer

設置api爲外部可訪問：

$ 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

5. 其餘

後面咱們會繼續爲你們補充如何使用Spinnaker管理和交付應用。
