如何在阿里云容器服务ACK上部署应用管理/发布系统Spinnaker

Spinnaker是一个开源的多云持续交付平台，可帮助您方便管理应用以及快速交付应用。

Spinnaker的两个主要功能是： 应用管理 , 应用交付

Applications, clusters, and server groups是Spinnaker中非常重要的几个概念， Load balancers and firewalls描述了如何向用户公开你的服务：

应用部署和部署策略：

在ACK上部署Spinnaker的步骤：
（1）创建一个ACK集群
（2）创建Spinnaker需要的Kubernetes资源
（3）配置Spinnaker的安装文件
（4）部署并访问Spinnaker

1. 创建集群

参考 创建阿里云容器服务ACK集群

2. 创建Spinnaker需要的Kubernetes资源

2.1 创建 Namespace

$ kubectl create ns spinnaker

2.2 创建ServiceAccount ClusterRoleBinding 资源用于 Halyard 部署 Spinnaker

rbac.yaml 文件内容：

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

运行以下命令创建资源：

$ kubectl create -f rbac.yaml

3. 配置Spinnaker的安装文件

Spinnaker是通过Halyard工具来管理配置和部署的。

3.1 部署halyard

hal-deployment.yaml 文件内容如下：

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

运行以下命令创建资源：

$ kubectl create -f hal-deployment.yaml

查看pod是否正常运行：

$ 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进入hal pod：

$ kubectl -n spinnaker exec -it hal-77b4cf787f-p25h5 bash

• 拷贝kubeconfig文件为~/.kube/config
• 启用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

• 添加一个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 选择Spinnaker的部署环境

运行以下命令：

$ 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 配置存储

Spinnaker需要外部安全可靠的存储服务来保留您的应用程序设置和已配置的Pipeline。由于这些数据很敏感，丢失的话恢复起来代价很高。 本次示例我们临时搭建一个Minio Service

• 部署Minio
  minio-deployment.yml文件内容如下：

---
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

设置MINIO_ACCESS_KEY MINIO_SECRET_KEY的值并部署Minio：

$ kubectl create -f minio-deployment.yaml

查看Pod运行状态和服务端口：

$ 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

创建job在Minio中创建bucket和path：
job.yaml内容如下：

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"

你需要记录 ENDPOINT  MINIO_ACCESS_KEY MINIO_SECRET_KEY 在下文会用到

• 编辑和配置存储信息
  在hal pod中继续执行以下步骤：

$ 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并访问服务

• 列出并选择一个版本 注意：此处会从Google Cloud上获取一个versions.yml文件， 请自行解决网络问题

$ 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)

• 选择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.

$ 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可外部访问

$ 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
  securely, and then register the intended Domain and IP addresses that your
  publicly facing services will be using.

+ Successfully updated UI security settings.

在浏览器中访问Spinnaker ui界面 http://xxx.xx.xx.xx:9000

注意： Spinnaker本身并没有用户管理模块， 在生产中使用的话，用户需要对接自己的认证系统， 参考[Spinnaker Authentication](https://www.spinnaker.io/setup/security/authentication/)

• 若需要外部访问Spinnaker API， 则需要做以下操作
  修改 Service spin-gate 为 type: LoadBalancer

设置api为外部可访问：

$ 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
