Managing Runtime Configs
Page last updated:
This topic explains how to define and manage named runtime configs with your service tile for Pivotal Cloud Foundry (PCF).
See the BOSH documentation for more information about runtime configs.
A runtime config is a section of the tile metadata that can define global deployment configurations. When a tile author includes a runtime config as a top-level key in the tile metadata, BOSH applies the runtime config to every VM in the deployment.
To the operator, a runtime config appears in Ops Manager as a tile with minimal configuration options. Runtime config tiles contain no stemcell, network, availability zone (AZ), or resource config information.
When you click Apply Changes, Ops Manager combines the runtime config information from every tile in the deployment and assigns each named runtime config a unique identifier. Ops Manager creates the name using the tile name, a generated GUID, and the runtime config name defined in the metadata in the following format:
Tile authors can add
runtime_configs as a top-level key in tile metadata. In this key, the tile author defines configuration properties that Ops Manager applies to all deployments. A tile can support any number of runtime configs.
A named runtime config, such as
MY-RUNTIME-CONFIG in the example below, can contain any number of addons. Each addon can contain any number of jobs.
To add a runtime config to a tile, add the following section to the tile metadata:
runtime_configs: - name: MY-RUNTIME-CONFIG runtime_config: | releases: - name: os-conf version: 15 addons: - name: MY-ADDON-NAME jobs: - name: MY-RUNTIME-CONFIG-JOB release: os-conf properties: MY-ADDON-NAME: ...
Replace the text in the example above with the following:
MY-RUNTIME-CONFIG: Choose a name for the runtime config.
MY-ADDON-NAME: Choose a name for the addon that contains the runtime config job.
MY-RUNTIME-CONFIG-JOB: Choose a name for the job the runtime config describes.
Important: The names you choose must be unique across a deployment. Pivotal recommends appending your product name or another unique identifier to each of the named items in the
Define the runtime config job properties in the
Tile authors can remove an existing runtime config from a tile by removing the reference from the metadata. When the operator upgrades the tile, Ops Manager detects the missing reference and deletes the runtime config.
Tile authors can create a tile that only contains a runtime config. The only release that a tile author must include in a runtime config tile is
os-conf. When creating a runtime config-only tile, a tile author is not required to define the following top-level keys:
The following example shows a runtime config-only tile with minimal configuration:
--- name: runtime-config-only-example-product product_version: "3.4" minimum_version_for_upgrade: "2.0" metadata_version: "2.0" label: 'Runtime Config Only Example Product' description: An example product to demonstrate runtime config features rank: 1 service_broker: false # Default value stemcell_criteria: os: ubuntu-trusty version: STEMCELL-VERSION releases: - name: os-conf file: os-conf version: '15' post_deploy_errands:  pre_delete_errands:  form_types: - name: example_form label: 'Example form' description: 'An example form' property_inputs: - reference: .properties.example_string label: 'Example string' property_blueprints: - name: example_string type: string configurable: true default: Pizza job_types:  runtime_configs: - name: example-runtime-config runtime_config: | releases: - name: os-conf version: 15 addons: - name: login jobs: - name: login-banner release: os-conf properties: login_banner: text: | (( .properties.example_string.value )).
In the example runtime config above, the
login-banner job prints a banner when a user logs into any VM in the deployment. The operator can use the default value defined in the
form_types section of the metadata or configure the banner by editing the Example string value in Ops Manager.
