  • kind: ResourceBinding

  • metadata (ObjectMeta)

  • spec (ResourceBindingSpec), required

    Spec represents the desired behavior.

  • status (ResourceBindingStatus)

    Status represents the most recently observed status of the ResourceBinding.

ResourceBindingSpec

      Name represents the name of the referent.

    • resource.namespace (string)

      Namespace represents the namespace for the referent. For non-namespace scoped resources(e.g. ‘ClusterRole’)，do not need specify Namespace, and for namespace scoped resources, Namespace is required. If Namespace is not specified, means the resource is non-namespace scoped.

      Replicas in target cluster

  • conflictResolution (string)

    ConflictResolution declares how potential conflict should be handled when a resource that is being propagated already exists in the target cluster.

    It defaults to “Abort” which means stop propagating to avoid unexpected overwrites. The “Overwrite” might be useful when migrating legacy cluster resources to Karmada, in which case conflict is predictable and can be instructed to Karmada take over the resource by overwriting.

  • failover (FailoverBehavior)

    Failover indicates how Karmada migrates applications in case of failures. It inherits directly from the associated PropagationPolicy(or ClusterPropagationPolicy).

    FailoverBehavior indicates failover behaviors in case of an application or cluster failure.

    • failover.application (ApplicationFailoverBehavior)

      Application indicates failover behaviors in case of application failure. If this value is nil, failover is disabled. If set, the PropagateDeps should be true so that the dependencies could be migrated along with the application.

  • gracefulEvictionTasks ([]GracefulEvictionTask)

    GracefulEvictionTasks holds the eviction tasks that are expected to perform the eviction in a graceful way. The intended workflow is: 1. Once the controller(such as ‘taint-manager’) decided to evict the resource that is referenced by current ResourceBinding or ClusterResourceBinding from a target cluster, it removes(or scale down the replicas) the target from Clusters(.spec.Clusters) and builds a graceful eviction task. 2. The scheduler may perform a re-scheduler and probably select a substitute cluster to take over the evicting workload(resource). 3. The graceful eviction controller takes care of the graceful eviction tasks and performs the final removal after the workload(resource) is available on the substitute cluster or exceed the grace termination period(defaults to 10 minutes).

    GracefulEvictionTask represents a graceful eviction task.

    • gracefulEvictionTasks.creationTimestamp (Time)

      CreationTimestamp is a timestamp representing the server time when this object was created. Clients should not set this value to avoid the time inconsistency issue. It is represented in RFC3339 form(like ‘2021-04-25T10:02:10Z’) and is in UTC.

      Populated by the system. Read-only.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • gracefulEvictionTasks.gracePeriodSeconds (int32)

      GracePeriodSeconds is the maximum waiting duration in seconds before the item should be deleted.

      If none of the groups satisfy the scheduling restrictions, then scheduling fails, which means no cluster will be selected.

      Note:

      1. ClusterAffinities can not co-exist with ClusterAffinity.
      2. If both ClusterAffinity and ClusterAffinities are not set, any cluster can be scheduling candidates.

      Potential use case 1: The private clusters in the local data center could be the main group, and the managed clusters provided by cluster providers could be the secondary group. So that the Karmada scheduler would prefer to schedule workloads to the main group and the second group will only be considered in case of the main group does not satisfy restrictions(like, lack of resources).

      Potential use case 2: For the disaster recovery scenario, the clusters could be organized to primary and backup groups, the workloads would be scheduled to primary clusters firstly, and when primary cluster fails(like data center power off), Karmada scheduler could migrate workloads to the backup clusters.

    • aggregatedStatus.status (RawExtension)

      Status reflects running status of current manifest.

      *RawExtension is used to hold extensions in external versions.

      To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.

      // Internal package:

      1. type MyAPIObject struct [
      2.     runtime.TypeMeta `json:",inline"`
      3.     MyPlugin runtime.Object `json:"myPlugin"`
      4. ]
      6. type PluginA struct [
      7.     AOption string `json:"aOption"`
      8. ]

      // External package:

      1. type MyAPIObject struct [
      2.     runtime.TypeMeta `json:",inline"`
      3.     MyPlugin runtime.RawExtension `json:"myPlugin"`
      4. ]
      6. type PluginA struct [
      7.     AOption string `json:"aOption"`
      8. ]

      // On the wire, the JSON will look something like this:

      1. [
      2.     "kind":"MyAPIObject",
      3.     "apiVersion":"v1",
      4.     "myPlugin": [
      5.         "kind":"PluginA",
      6.         "aOption":"foo",
      7.     ],
      8. ]

      So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package’s DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)*
