They are used to tag resources with metadata that can be used to filter and group resources. Labels are included in the response body of a request to retrieve a resource.

            Labels are user-specified key/value pairs that are attached to API Resources. They are queryable, identifying attributes of a resource, but they do not affect the operation of CloudFoundry.


            For example, an app may be assigned a label with key sensitive and possible values true or false.


            Users could then find all sensitive apps with a selector for sensitive=true, resulting in a response containing only apps having the label key sensitive with a label value of true.


            Labels

            Labels allow users to apply identifying attributes to resources that are meaningful to the user, but not the CloudFoundry system.


            Examples may include (but are not limited to):


            "production" : "true" or "production" : "false"

            "env" : "dev" or "env" : "test" or "env" : "prod"

            "chargeback-code" : "abc123"

            Label keys

            Label keys are made up of an (optional) prefix, and name. If a prefix is present, it is separated from the name by a /. Prefixes are dns names intended to enable namespacing of label keys.


            A label key prefix must adhere to the following restrictions:


            Length: 0-253 characters

            Allowed characters: alphanumeric ( [a-z0-9A-Z] ), -, and .

            DNS subdomain format (series of subdomain labels separated by .)

            A label key name must adhere to the following restrictions:


            Length: 1-63 characters

            Allowed characters: alphanumeric ( [a-z0-9A-Z] ), -, _, and .

            Must begin and end with an alphanumeric character

            Label values

            Label values must adhere to the following restrictions:


            Length: 0-63 characters

            Allowed characters: alphanumeric ( [a-z0-9A-Z] ), -, _, and .

            Must begin and end with an alphanumeric character

When a service instance is being updated, the service broker is sent the annotations of the space and organization in which the service instance resides. When a service binding is being created, the service broker is sent annotations of any associated app, and the space and organization in which the binding resides. Only annotations with a prefix (e.g. company.com/contacts) are sent to service brokers.


            Examples may include (but are not limited to):


            "contact info": "bob@example.com jane@example.com"

            "library versions": "Spring: 5.1, Redis Client: a184098. yaml parser: 38"

            "git-sha": "d56fe0367554ae5e878e37ed6c5b9a82f5995512"

            Annotation keys

            Annotation keys are made up of an (optional) prefix and name. If a prefix is present, it is separated from the name by a /. Prefixes are DNS names intended to enable namespacing of annotation keys.


            An annotation key prefix must adhere to the following restrictions:


            Length: 0-253 characters

            Allowed characters: a-z, A-Z, 0-9, -, and .; emojis cannot be used in keys

            DNS subdomain format (series of subdomain annotations separated by .)

            An annotation key name must adhere to the following restrictions:


            Length: 1-63 characters

            Allowed characters: a-z, A-Z, 0-9, -, _, and .; emojis cannot be used in keys

            Must begin and end with an alphanumeric character

            Annotation values

            Annotation values must adhere to the following restrictions:


            Length: 0-5000 unicode characters
