TODO(jdef) we use a Locker to guard against concurrent task state changes, but it would bereally, really nice to avoid doing this.

makePodKey constructs etcd paths to pod items enforcing namespace rules.

NewDefaultProcurement returns the default procurement strategy that combines validation and responsible Mesos resource procurement.

NodeProcurement updates t.Spec in preparation for the task to be launched on the slave associated with the offer.

PodResourcesProcurement converts k8s pod cpu and memory resource requirements into mesos resource allocations.

PortsProcurement convert host port mappings into mesos port resource allocations.

reconstruct a task from metadata stashed in a pod entry.

ValidateProcurement checks that the offered resources are kosher, and if not panics.

maps a Container.HostPort to the same exact offered host port, ignores .HostPort = 0.

same as HostPortMappingFixed, except that .HostPort of 0 are mapped to any port offered.

TODO(jdef) move this somewhere else.

A struct that describes a pod task.

state store for pod tasks.

AllOrNothingProcurement provides a convenient wrapper around multiple Procurement objectives: the failure of any Procurement in the set results in Procure failing.

FitPredicate implementations determine if the given task "fits" into offered Mesos resources.

Procurement funcs allocate resources for a task from an offer.
