Overcoming failure to create service instance

Purpose

Starting with PCF v1.8, a quota has been put in place for service key creation, which is set by default at zero; this is intended to prevent accidental creation of service instance resources. For example, when attempting to create a circuit breaker service instance in Spring Cloud Services (SCS), a failure may occur when the value for "service keys" is set to zero. This KB describes how to set the value of service keys to -1 (unlimited), which should enable the service instance to be created.

Symptoms

The most common and general symptom is an error such as this:

Server error, status code: 400, error code: 360002, message: The service key is invalid: quota service_keys_quota_exceeded

The following error may also be seen in the smoke test logs:

Last Operation

cf service test-p-circuit-breaker-dashboard-1521937116

Environment

Resolution

Procedure

1. Verified that "total_service_keys": 0

CF_TRACE=true cf quota 

for example...

CF_TRACE=true cf quota p-spring-cloud-services
....
},
      "entity": {
        "name": "p-spring-cloud-services",
        "non_basic_services_allowed": true,
        "total_services": -1,
        "total_routes": 1000,
        "total_private_domains": 0,
       "memory_limit": 153600,
        "trial_db_allowed": false,
        "instance_memory_limit": -1,
        "app_instance_limit": -1,
        "app_task_limit": -1,
        "total_service_keys": 0,
        "total_reserved_route_ports": 0
      }

.....

2.  Update the service keys

    cf curl -X PUT /v2/quota_definitions/<guid from URL in step 1, above> -d '{"total_service_keys": -1}'
