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
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:

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.

- 访问Spinnaker服务
kubectl -n spinnaker edit svc spin-deck
修改提供ui服务的spin-deck
service资源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.

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

设置api为外部可访问:
$ hal config security api edit --override-base-url http://xx.xx.xxx.xx:8084

Success
+ Get API security settings
Success
+ Edit API security settings
Success
