本页面介绍如何部署 Kf Cloud Service Broker for Google Cloud，并使用它来预配或取消预配支持性资源。如需详细了解 Kf Cloud Service Broker，请阅读概念和架构。
创建环境变量
Linux
export PROJECT_ID=YOUR_PROJECT_ID export CLUSTER_PROJECT_ID=YOUR_PROJECT_ID export CLUSTER_NAME=kf-cluster export INSTANCE_NAME=cloud-service-broker export COMPUTE_REGION=us-central1
Windows Powershell
Set-Variable -Name PROJECT_ID -Value YOUR_PROJECT_ID Set-Variable -Name CLUSTER_PROJECT_ID -Value YOUR_PROJECT_ID Set-Variable -Name CLUSTER_NAME -Value kf-cluster Set-Variable -Name INSTANCE_NAME -Value cloud-service-broker Set-Variable -Name COMPUTE_REGION -Value us-central1
设置 Kf Cloud Service Broker 数据库
创建 Cloud SQL for MySQL 实例。
gcloud sql instances create ${INSTANCE_NAME} --cpu=2 --memory=7680MB --require-ssl --region=${COMPUTE_REGION}在 Cloud SQL for MySQL 实例中创建名为
servicebroker的数据库。gcloud sql databases create servicebroker -i ${INSTANCE_NAME}创建 Kf Cloud Service Broker 要使用的用户名和密码。
gcloud sql users create csbuser -i ${INSTANCE_NAME} --password=csbpassword
为 Kf Cloud Service Broker 设置 Google 服务账号 (GSA)
创建 Google 服务账号。
gcloud iam service-accounts create csb-${CLUSTER_NAME}-sa \ --project=${CLUSTER_PROJECT_ID} \ --description="GSA for CSB at ${CLUSTER_NAME}" \ --display-name="csb-${CLUSTER_NAME}"向服务账号授予
roles/cloudsql.client权限。这是通过 Cloud SQL Auth 代理将 Kf Cloud Service Broker pod 连接到 Cloud SQL for MySQL 实例所必需的。gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \ --member="serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \ --role="roles/cloudsql.client"向服务账号授予其他 Google Cloud 权限。
gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \ --member="serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \ --role="roles/compute.networkUser"gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \ --member="serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \ --role="roles/cloudsql.admin"gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \ --member="serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \ --role="roles/redis.admin"验证权限。
gcloud projects get-iam-policy ${CLUSTER_PROJECT_ID} \ --filter='bindings.members:serviceAccount:"CSB_SERVICE_ACCOUNT_NAME"' \ --flatten="bindings[].members"
为 Kf Cloud Service Broker 设置 Workload Identity
将 Google 服务账号与 Kubernetes 服务账号绑定。
gcloud iam service-accounts add-iam-policy-binding "csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \ --project=${CLUSTER_PROJECT_ID} \ --role="roles/iam.workloadIdentityUser" \ --member="serviceAccount:${CLUSTER_PROJECT_ID}.svc.id.goog[kf-csb/csb-user]"验证绑定。
gcloud iam service-accounts get-iam-policy "csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \ --project=${CLUSTER_PROJECT_ID}
设置 Kubernete Secret 以与 Kf Cloud Service Broker 共享配置
创建一个 config.yml 文件。
cat << EOF >> ./config.yml gcp: credentials: "" project: ${CLUSTER_PROJECT_ID}db: host: 127.0.0.1 password: csbpassword user: csbuser tls: false api: user: servicebroker password: password EOF创建
kf-csb命名空间。kubectl create ns kf-csb创建 Kubernetes Secret。
kubectl create secret generic csb-secret --from-file=config.yml -n kf-csb
安装 Kf Cloud Service Broker
下载
kf-csb.yml。gcloud storage cp gs://kf-releases/csb/v1.0.0/kf-csb.yaml /tmp/kf-csb.yaml修改
/tmp/kf-csb.yaml并将占位符替换为最终值。在下面的示例中，使用sed。sed -i "s|<GSA_NAME>|csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com|g" /tmp/kf-csb.yamlsed -i "s|<INSTANCE_CONNECTION_NAME>|${CLUSTER_PROJECT_ID}:${COMPUTE_REGION}:${INSTANCE_NAME}|g" /tmp/kf-csb.yamlsed -i "s|<DB_PORT>|3306|g" /tmp/kf-csb.yaml应用 Kf Cloud Service Broker 的 yaml。
kubectl apply -f /tmp/kf-csb.yaml验证 Kf Cloud Service Broker 安装状态。
kubectl get pods -n kf-csb
创建 Service Broker
kf create-service-broker cloud-service-broker servicebroker password http://csb-controller.kf-csb/验证安装
查看 Marketplace 中的可用服务。
kf marketplace如果一切都已正确安装和配置，您应该会看到以下内容：
$ kf marketplace
