Issue/Introduction
In an environment, where there is a lot of service instance deployments, you can check what apps are bound to the service instance via cf cli.
This articles covers how to determine if apps are bound to the service.
Environment
TAS
Resolution
Get a full list of BOSH deployments using the command: bosh ds --column=name
Example bosh deployments output:
cf-cd7cc3cd4db8a9288f57 service-instance_1cc6031d-2ca4-4743-8449-533a8ec54524 service-instance_0e6b921e-5d04-44ad-9e21-2cd140f0c4f2
or else to check in cf cli use command:
cf curl /v3/service_instances
To find service bindings for these deployments use CF CLI command:
cf curl /v3/service_instances/<guid>/service_bindings
Where the <guid> variable is presented in the bosh ds output above, or else can be retrieved in cf cli with command:
cf service <service name> --guid
Example 1
This service is not bound to any application. In this example, no results were found. This deployment is not being utilized by any of the cf deployed apps.
cf curl /v3/service_instances/0e6b921e-5d04-44ad-9e21-2cd140f0c4f2/service_bindings
Output:
{ "total_results": 0, "total_pages": 1, "prev_url": null, "next_url": null, "resources": [] }
Example 2
This service is bound to an application. The output demonstrates that 1 result was found.
In this example, to narrow down the app bound to this service by name use command:
cf curl /v3/service_instances/1cc6031d-2ca4-4743-8449-533a8ec54524/service_bindings
Output:
{ "total_results": 1, "total_pages": 1, "prev_url": null, "next_url": null, "resources": [ { "metadata": { "guid": "97e0d2b6-3cc2-4c56-993e-29069eaf6b28", "url": "/v2/service_bindings/97e0d2b6-3cc2-4c56-993e-29069eaf6b28", "created_at": "2021-09-09T16:38:38Z", "updated_at": "2021-09-09T16:38:39Z" }, "entity": { "app_guid": "70785a53-6124-40d6-901c-7df16f03c1ef", "service_instance_guid": "1cc6031d-2ca4-4743-8449-533a8ec54524", "credentials": { "hostname": "1cc6031d-2ca4-4743-8449-533a8ec54524.mysql.service.internal", "jdbcUrl": "jdbc:mysql://1cc6031d-2ca4-4743-8449-533a8ec54524.mysql.service.internal:3306/service_instance_db?user=97e0d2b63cc24c56993e29069eaf6b28&password=redacted&sslMode=VERIFY_IDENTITY&useSSL=true&requireSSL=true&enabledTLSProtocols=TLSv1.2&serverSslCert=/etc/ssl/certs/ca-certificates.crt", "name": "service_instance_db", "password": "redacted", "port": 3306, "tls": { "cert": { "ca": "-----BEGIN CERTIFICATE-----\n\n-----END CERTIFICATE-----\n" } }, "uri": "mysql://mysql.service.internal:3306/service_instance_db?reconnect=true", "username": "" }, "binding_options": {}, "gateway_data": null, "gateway_name": "", "syslog_drain_url": null, "volume_mounts": [], "name": null, "last_operation": { "type": "create", "state": "succeeded", "description": "", "updated_at": "2021-09-09T16:38:39Z", "created_at": "2021-09-09T16:38:39Z" }, "app_url": "/v2/apps/70785a53-6124-40d6-901c-7df16f03c1ef", "service_instance_url": "/v2/service_instances/1cc6031d-2ca4-4743-8449-533a8ec54524", "service_binding_parameters_url": "/v2/service_bindings/97e0d2b6-3cc2-4c56-993e-29069eaf6b28/parameters" } } ] }
Additional Information
The command can run for api v2 and api v3, for example:
cf curl /v2/service_instances or cf curl /v3/service_instances
