安装 GCP Service Broker

本文档是 GCP Service Broker 的 GitHub 代码库上显示的文档修订版。

前提条件

  1. 安装了 Kf 的集群。
  2. gcloud：按照这些说明安装 gcloud CLI。
  3. kubectl：安装 gcloud 后，运行 gcloud components install kubectl。
  4. helm：按照这些说明安装 helm CLI。
  5. git：需要 Git 才能克隆代码库。

配置

选择项目

选择要用于本教程其余部分的 Google Cloud 项目。它应该是您的 Kf 集群所用的项目。

您必须是所选项目的所有者。（可选）更改以下值以反映您的环境，然后在终端中设置以下环境变量：

export PROJECT_ID=$(gcloud config get-value project)
export SERVICE_ACCOUNT_NAME=kf-gcp-broker

为 Broker 创建服务账号

  1. 创建服务账号：

    gcloud iam service-accounts create $SERVICE_ACCOUNT_NAME

  2. 创建新凭据以允许 Broker 进行身份验证，并将凭据下载到 key.json：

    gcloud iam service-accounts keys create key.json --iam-account $SERVICE_ACCOUNT_NAME@$PROJECT_ID.iam.gserviceaccount.com

  3. 向 Broker 授予项目所有者权限：

    gcloud projects add-iam-policy-binding $PROJECT_ID --member serviceAccount:$SERVICE_ACCOUNT_NAME@$PROJECT_ID.iam.gserviceaccount.com --role "roles/owner"

启用必需的 API

现在，您需要启用 API 以使 Broker 预配资源。

Broker 具有运行它所需的一些 API，还有一些 API 是可选的，但必须启用才能预配特定类型的资源。

需要 Cloud Resource Manager 和 Identity and Access Management API 才能运行代理。如需启用它们，请输入以下命令：

gcloud services enable cloudresourcemanager.googleapis.com iam.googleapis.com --project $PROJECT_ID

启用 API

为了在项目上预配 Cloud 服务，Kf 建议至少启用以下 API：

  1. CloudSQL API
  2. CloudSQL Admin API
  3. Pub/Sub API
  4. Redis API
  5. Storage API

GCP Service Broker 还支持多种其他服务，您可以通过启用此处列出的 API 来添加对这些服务的支持。

安装 Service Broker

  1. 将 GCP Service Broker 克隆到本地工作站，并使用 cd 切换到该工作站：

    git clone --depth=1 "https://github.com/GoogleCloudPlatform/gcp-service-broker"
cd gcp-service-broker/deployments/helm/gcp-service-broker

  2. 更新 Helm 图表的依赖项：

    helm dependency update

  3. 修改文件 values.yaml 并将 broker.service_account_json 的值设置为包含 key.json 的全部内容的字符串。

    可选：通读其余属性并更改任何适合您的环境所需的内容。

    # ...
broker:
  # ...
  service_account_json: "contents of key.json go here"
# ...

  4. 如果在生产环境中运行，请将 mysql.embedded 设置为 false，并为具有自动备份和故障切换的外部 MySQL 数据库提供凭据。

  5. 为 GCP Service Broker 创建 Kubernetes 命名空间：

    kubectl create namespace gcp-service-broker

  6. 安装代理：

    helm install gcp-service-broker --set svccat.register=false --namespace gcp-service-broker .

  7. 向 Kf 注册代理：

    kf create-service-broker gcp-service-broker \
  "$(kubectl get secret gcp-service-broker-auth -n gcp-service-broker -o jsonpath='{.data.username}' | base64 --decode)" \
  "$(kubectl get secret gcp-service-broker-auth -n gcp-service-broker -o jsonpath='{.data.password}' | base64 --decode)" \
  "http://gcp-service-broker.gcp-service-broker.svc.cluster.local"

确认安装 Broker

运行 kf marketplace。您应看到如下输出：
