gcp-service-broker

Cloud Foundry Service Broker for Google Cloud Platform

Depends on lager and gorilla/mux.

Requires Go 1.7 and the associated buildpack.

Examples

See the examples folder.

Prerequisites

Set up a GCP Project

1. go to Google Cloud Console and sign up, walking through the setup wizard
2. next to the Google Cloud Platform logo in the upper left-hand corner, click the dropdown and select "Create Project"
3. give your project a name and click "Create"
4. when the project is created (a notification will show in the upper right), refresh the page.

Enable APIS

1. Navigate to API Manager > Library.
2. Enable the Google Cloud Resource Manager API
3. Enable the Google Identity and Access Management (IAM) API
4. If you want to enable Cloud SQL as a service, enable the Cloud SQL API
5. If you want to enable BigQuery as a service, enable the BigQuery API
6. If you want to enable Cloud Storage as a service, enable the Cloud Storage API
7. If you want to enable Pub/Sub as a service, enable the Cloud Pub/Sub API
8. If you want to enable Bigtable as a service, enable the Bigtable Admin API

Create a root service account

1. From the GCP console, navigate to IAM & Admin > Service accounts and click Create Service Account.
2. Enter a Service account name.
3. Select the checkbox to Furnish a new Private Key, and then click Create.
4. Save the automatically downloaded key file to a secure location.
5. Navigate to IAM & Admin > IAM and locate your service account.
6. From the dropdown on the right, choose Project > Owner and click Save.

Set up a backing database

1. create new MySQL instance
2. run CREATE DATABASE servicebroker;
3. run CREATE USER '<username>'@'%' IDENTIFIED BY '<password>';
4. run GRANT ALL PRIVILEGES ON servicebroker.* TO '<username>'@'%' WITH GRANT OPTION;
5. (optional) create SSL certs for the database and save them somewhere secure

Set required env vars - if deploying as an app, add these to missing-properties.yml

• ROOT_SERVICE_ACCOUNT_JSON (the string version of the credentials file created for the Owner level Service Account)
• SECURITY_USER_NAME (a username to sign all service broker requests with - the same one used in cf create-service-broker)
• SECURITY_USER_PASSWORD (a password to sign all service broker requests with - the same one used in cf create-service-broker)
• DB_HOST (the host for the database to back the service broker)
• DB_USERNAME (the database username for the service broker to use)
• DB_PASSWORD (the database password for the service broker to use)

optional env vars - if deploying as an app, optionally add these to missing-properties.yml

• DB_PORT (defaults to 3306)
• CA_CERT
• CLIENT_CERT
• CLIENT_KEY
• CLOUDSQL_CUSTOM_PLANS (A map of plan names to string maps with fields guid, name, description, tier, pricing_plan, max_disk_size, display_name, and service (Cloud SQL's service id)) - if unset, the service will be disabled. e.g.,

{
    "test_plan": {
        "name": "test_plan",
        "description": "testplan",
        "tier": "D8",
        "pricing_plan": "PER_USE",
        "max_disk_size": "15",
        "display_name": "FOOBAR",
        "service": "4bc59b9a-8520-409f-85da-1c7552315863"
    }
}

• BIGTABLE_CUSTOM_PLANS (A map of plan names to string maps with fields guid, name, description, storage_type, num_nodes, display_name, and service (Bigtable's service id)) - if unset, the service will be disabled. e.g.,

{
    "bt_plan": {
        "name": "bt_plan",
        "description": "Bigtable basic plan",
        "storage_type": "HDD",
        "num_nodes": "5",
        "display_name": "Bigtable Plan",
        "service": "b8e19880-ac58-42ef-b033-f7cd9c94d1fe"
    }
}

• SPANNER_CUSTOM_PLANS (A map of plan names to string maps with fields guid, name, description, num_nodes display_name, and service (Spanner's service id)) - if unset, the service will be disabled. e.g.,

{
    "spannerplan": {
        "name": "spannerplan",
        "description": "Basic Spanner plan",
        "num_nodes": "15",
        "display_name": "Spanner Plan",
        "service": "51b3e27e-d323-49ce-8c5f-1211e6409e82"
    }
}

Usage

As an App

Update the manifest with ENV vars

1. replace any blank variables that are in manifest.yml with your own ENV vars

Push the service broker to CF and enable services

1. cf push gcp-service-broker
2. cf create-service-broker <service broker name> <username> <password> <service broker url>
3. (for all applicable services, e.g.) cf enable-service-access google-pubsub

As a Tile

Import the product into Ops Manager

1. Click "Import a Product" and upload the .pivotal file from the product directory

Add the product to your Dashboard

1. Click the plus icon next to the uploaded product

Configure the Service Broker

1. Click on the tile and fill in any required fields (tabs will be orange if updates are needed)
2. Once the tile is green and updates are applied, review the service/plan access and update if necessary using cf disable-service-access. By default, all services and plans are enabled except CloudSQL, Bigtable, and Spanner (unless plans have been saved for them). If you wish to change this, you'll need to use the cf cli's service-access commands.

(Optional) Increase the default provision/bind timeout

It is advisable, if you want to use CloudSQL, to increase the default timeout for provision and bind operations to 90 seconds. CloudFoundry does not, at this point in time, support asynchronous binding, and CloudSQL bind operations may exceed 60 seconds. To change this setting, set broker_client_timeout_seconds = 90

Use!

For example:

• cf create-service pubsub default foobar
• cf bind-service myapp foobar -c '{"role": "pubsub.admin"}'

Notes:

• create-service calls take the following optional custom parameters, all as strings.

• bind-service calls require a role, except for Cloud SQL.
