Enum Constant Detail

UNKNOWN

public static final Protos.SlaveInfo.Capability.Type UNKNOWN

 This must be the first enum value in this list, to
 ensure that if 'type' is not set, the default value
 is UNKNOWN. This enables enum values to be added
 in a backwards-compatible way. See: MESOS-4997.
 

UNKNOWN = 0;

MULTI_ROLE

public static final Protos.SlaveInfo.Capability.Type MULTI_ROLE

 This expresses the ability for the agent to be able
 to launch tasks of a 'multi-role' framework.
 

MULTI_ROLE = 1;

HIERARCHICAL_ROLE

public static final Protos.SlaveInfo.Capability.Type HIERARCHICAL_ROLE

 This expresses the ability for the agent to be able to launch
 tasks, reserve resources, and create volumes using resources
 allocated to a 'hierarchical-role'.
 NOTE: This capability is required specifically for creating
 volumes because a hierchical role includes '/' (slashes) in them.
 Agents with this capability know to transform the '/' (slashes)
 into ' ' (spaces).
 

HIERARCHICAL_ROLE = 2;

RESERVATION_REFINEMENT

public static final Protos.SlaveInfo.Capability.Type RESERVATION_REFINEMENT

 This capability has three effects for an agent.
 (1) The format of the checkpointed resources, and
     the resources reported to master.
     These resources are reported in the "pre-reservation-refinement"
     format if none of the resources have refined reservations. If any
     of the resources have refined reservations, they are reported in
     the "post-reservation-refinement" format. The purpose is to allow
     downgrading of an agent as well as communication with a pre-1.4.0
     master until the reservation refinement feature is actually used.
     See the 'Resource Format' section for more details.
 (2) The format of the resources reported by the HTTP endpoints.
     For resources reported by agent endpoints, the
     "pre-reservation-refinement" format is "injected" if possible.
     That is, resources without refined reservations will have the
     `Resource.role` and `Resource.reservation` set, whereas
     resources with refined reservations will not.
     See the 'Resource Format' section for more details.
 (3) The ability for the agent to launch tasks, reserve resources, and
     create volumes using resources that have refined reservations.
     See `ReservationInfo.reservations` section for more details.
 NOTE: Resources are said to have refined reservations if it uses the
 `Resource.reservations` field, and `Resource.reservations_size() > 1`.
 

RESERVATION_REFINEMENT = 3;

RESOURCE_PROVIDER

public static final Protos.SlaveInfo.Capability.Type RESOURCE_PROVIDER

 This expresses the ability for the agent to handle resource
 provider related operations. This includes the following:
 (1) The ability to report resources that are provided by some
     local resource providers through the resource provider API.
 (2) The ability to provide operation feedback. This also means
     that this capability is a prerequisite for full support of
     feedback for operations on agent default resources. If an
     agent has the mandatory AGENT_OPERATION_FEEDBACK capability
     set but not the RESOURCE_PROVIDER capability, then
     operations on agent default resources which request feedback
     will not be allowed.
 

RESOURCE_PROVIDER = 4;

RESIZE_VOLUME

public static final Protos.SlaveInfo.Capability.Type RESIZE_VOLUME

 This expresses the capability for the agent to handle persistent volume
 resize operations safely. This capability is turned on by default.
 

RESIZE_VOLUME = 5;

AGENT_OPERATION_FEEDBACK

public static final Protos.SlaveInfo.Capability.Type AGENT_OPERATION_FEEDBACK

 This expresses the ability of the agent to handle operation feedback
 for operations on agent default resources.
 Note that full support for this feature also requires the
 RESOURCE_PROVIDER capability; if you would like the agent to
 handle feedback for operations on agent default resources, the
 RESOURCE_PROVIDER capability should be set as well.
 

AGENT_OPERATION_FEEDBACK = 6;

AGENT_DRAINING

public static final Protos.SlaveInfo.Capability.Type AGENT_DRAINING

 This expresses the ability for the agent to automatically drain tasks
 in preparation for operator maintenance. This capability is required.
 

AGENT_DRAINING = 7;

TASK_RESOURCE_LIMITS

public static final Protos.SlaveInfo.Capability.Type TASK_RESOURCE_LIMITS

 This expresses the ability for the agent to launch tasks which specify
 resource limits for CPU and/or memory.
 

TASK_RESOURCE_LIMITS = 8;

Field Detail

UNKNOWN_VALUE

public static final int UNKNOWN_VALUE

 This must be the first enum value in this list, to
 ensure that if 'type' is not set, the default value
 is UNKNOWN. This enables enum values to be added
 in a backwards-compatible way. See: MESOS-4997.
 

UNKNOWN = 0;

HIERARCHICAL_ROLE_VALUE
