> A framework instance may offer specific capabilities to the cluster: storage,
> smartly-balanced request handling across deployed tasks, access to 3rd party
> services outside of the cluster, etc. These capabilities may or may not be
> utilized by all, or even most mesos clusters. However, it should be possible
> for processes running in the cluster to discover capabilities or features of
> frameworks in order to achieve a higher level of functionality and a more
> seamless integration experience across the cluster.
> A rich discovery API attached to the FrameworkInfo could result in some form
> of early lock-in: there are probably many ways to realize cross-framework
> integration and external services integration that we haven't considered yet.
> Rather than over-specify a discovery info message type at the framework level
> I think FrameworkInfo should expose a **very generic** way to supply metadata
> for interested consumers (other processes, tasks, etc).
> Adding a Labels field to FrameworkInfo reuses an existing message type and
> seems to fit well with the overall intent: attaching generic metadata to a
> framework instance. These labels should be visible when querying a mesos
> master's state.json endpoint.
