Cloud Foundry Services

This project is a bosh release containing services that work with Cloud Foundry v2.

Installation

$ ./update
$ echo "---\ndev_name: cf-services" > config/dev.yml
$ bosh create release --force
$ bosh -n upload release

Your bosh will how have this bosh release available with the name cf-services

$ bosh releases                  

+-------------+-----------+-------------+
| Name        | Versions  | Commit Hash |
+-------------+-----------+-------------+
...
| cf-services | 0.1-dev   | 7e5dbbf3+   |
+-------------+-----------+-------------+

Usage

You can now include one or more of these services (gateway and nodes) in your Cloud Foundry deployment file. In the examples below, PostgreSQL will be deployed.

First, add the release to the releases section:

---
name: cf
director_uuid: UUID
releases:
- name: appcloud
  version: 131.7-dev
- name: cf-services
  version: 0.1-dev
...

Next, describe two new jobs after all other jobs. One for the postgresql_gateway job template and another for the first plan that will be offered to users, via postgresql_node job template.

jobs:
...
- name: service_gateways
  template:
  - postgresql_gateway
  release: cf-services
  resource_pool: small
  instances: 1
  networks:
  - name: default
    default:
    - dns
    - gateway
  properties:
    uaa_endpoint: http://uaa.aws.drniccloud.com
    uaa_client_id: cf
    uaa_client_auth_credentials:
      username: services
      password: c1oudc0w
- name: postgresql_service_node
  template:
  - postgresql_node
  release: cf-services
  instances: 1
  resource_pool: small
  persistent_disk: 4096
  networks:
  - name: default
    default:
    - dns
    - gateway
  properties:
    postgresql_node:
      plan: default

Note: each job above specifies release: cf-service.

The configurable aspects above are the amount of persistent_disk (set to 4G above) for the job to share amongst the provisioned databases, and the plan to be offered by the initial provisioned postgresql_service_node job (plan: default).

Also, the uaa_client_auth_credentials must match one of those within the UAA properties configuration.

Next, ensure that any other Cloud Foundry jobs within the deployment file explicitly reference their bosh release.

For example, if you have a colocated job core containing many jobs of the appcloud release (see bosh releases output for its name within your bosh), then include release: appcloud in each of your original jobs:

jobs:
- name: core
  template:
  - syslog_aggregator
  - nats
  - postgres
  - health_manager_next
  - collector
  - debian_nfs_server
  - login
  release: appcloud
  instances: 1
  resource_pool: medium
  persistent_disk: 8192
  networks:
  - name: default
    default:
    - dns
    - gateway
  properties:
    db: databases
...

Next, specify the available plans. The service gateway needs to know about all available plans and it educates the Cloud Controller about them once its running. Each job using the postgresql_node job template needs to state which specific plan it will run. Above, we assumed there was a plan called default.

Let's now describe this default plan, and the authentication credentials for the gateway. This configuration is within the properties section of your deployment file:

properties:
...
  service_plans:
    postgresql:
      default:
        job_management:
          high_water: 1400
          low_water: 100
        configuration:
          lifecycle:
            enable: false
          warden:
            enable: false
  postgresql_node:
    supported_versions:
    - '9.1'
    default_version: '9.1'
    password: c1oudc0wc1oudc0w
  postgresql_gateway:
    cc_api_version: v2
    token: c1oudc0wc1oudc0w
    default_plan: default
    supported_versions:
    - '9.1'
    version_aliases:
      current: '9.1'

The service plan default is described from the properties.service_plans.postgresql.default key name above.

Deploy and enable services

There are two remaining steps to deploy and use the services:

• deploy the update bosh deployment file above (using bosh CLI)
• register the service (using cf CLI)

First, run bosh deploy to compile the additional packages and provision/apply the new job VMs:

$ bosh deployment deployments/cf.yml
$ bosh deploy

The service gateway and initial service node are now running and will appear to your Cloud Foundry users (BUT, please ahead, do not stop yet!).

$ cf info --services

Finally, install the admin-cf-plugin plugin for cf CLI and register the new service gateway:

$ gem install admin-cf-plugin
$ cf create-service-auth-token postgresql core --token c1oudc0wc1oudc0w

Troubleshooting

If you do not create the service token via the admin-cf-plugin plugin above, your users will not be able to create services.

$ cf create-service
