    spec:

    root:
    routerType: Splitter
    routes:
    - service: mymodel1
    weight: 20
    - service: mymodel2
    weight: 80

    - service: mymodel1
    condition: "{ .input.userId == 1 }"
    - service: mymodel2
    condition: "{ .input.userId == 2 }"
    

    Scoring a case using a model ensemble consists of scoring it using each model separately, then combining the results into a single scoring result using one of the pre-defined combination methods.

    Tree Ensemble constitutes a case where simple algorithms for combining results of either classification or regression trees are well known. Multiple classification trees, for example, are commonly combined using a “majority-vote” method. Multiple regression trees are often combined using various averaging techniques. e.g tagging models with segment identifiers and weights to be used for their combination in these ways.

    kind: InferenceGraph
    metadata:
    name: ensemble
    spec:
    nodes:
    root:

    data: $response
    ensembleModel:
    routerType: Ensemble
    routes:
    - service: sklearn-model
    - service: xgboost-model
    

    Scoring a case using a sequence, or chain of models allows the output of one model to be passed in as input to the subsequent models.

    In the flow described below, the pre_processing node base64 encodes the image and passes it to two model nodes in the flow. The encoded data is available to both these nodes for classification. The second node i.e. dog-breed-classification takes the original input from the pre_processing node along-with the response from the cat-dog-classification node to do further classification of the dog breed if required.

    kind: InferenceGraph
    metadata:
    name: dog-breed-classification
    spec:

The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion. Init containers cannot currently be added or removed. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/

      priorityClassName
      string
      (Optional)

      If specified, indicates the pod’s priority. “system-node-critical” and “system-cluster-critical” are two special keywords which indicate the highest priorities with the former being the highest priority. Any other name must be defined by creating a PriorityClass object with that name. If not specified, the pod priority will be default or zero if there is no default.

      priority
      int32
      (Optional)

      The priority value. Various system components use this field to find the priority of the pod. When Priority Admission Controller is enabled, it prevents users from setting this field. The admission controller populates this field from PriorityClassName. The higher the value, the higher the priority.

      dnsConfig
      Kubernetes core/v1.PodDNSConfig

If unset or empty, the “legacy” RuntimeClass will be used, which is an implicit class with an empty definition that uses the default runtime handler. More info: https://git.k8s.io/enhancements/keps/sig-node/585-runtime-class This is a beta feature as of Kubernetes v1.14.

      enableServiceLinks
      bool
      (Optional)

      overhead
      Kubernetes core/v1.ResourceList
      (Optional)

      Overhead represents the resource overhead associated with running a pod for a given RuntimeClass. This field will be autopopulated at admission time by the RuntimeClass admission controller. If the RuntimeClass admission controller is enabled, overhead must not be set in Pod create requests. The RuntimeClass admission controller will reject Pod create requests which have the overhead already set. If RuntimeClass is configured and selected in the PodSpec, Overhead will be set to the value defined in the corresponding RuntimeClass, otherwise it will remain unset and treated as zero. More info: https://git.k8s.io/enhancements/keps/sig-node/688-pod-overhead/README.md This field is beta-level as of Kubernetes v1.18, and is only honored by servers that enable the PodOverhead feature.

      setHostnameAsFQDN
      bool
      (Optional)

      If true the pod’s hostname will be configured as the pod’s FQDN, rather than the leaf name (the default). In Linux containers, this means setting the FQDN in the hostname field of the kernel (the nodename field of struct utsname). In Windows containers, this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters to FQDN. If a pod does not have FQDN, this has no effect. Default to false.

      os
      Kubernetes core/v1.PodOS
      (Optional)

      Specifies the OS of the containers in the pod. Some pod and container fields are restricted if this is set.

      If the OS field is set to linux, the following fields must be unset: -securityContext.windowsOptions

      If the OS field is set to windows, following fields must be unset: - spec.hostPID - spec.hostIPC - spec.securityContext.seLinuxOptions - spec.securityContext.seccompProfile - spec.securityContext.fsGroup - spec.securityContext.fsGroupChangePolicy - spec.securityContext.sysctls - spec.shareProcessNamespace - spec.securityContext.runAsUser - spec.securityContext.runAsGroup - spec.securityContext.supplementalGroups - spec.containers[].securityContext.seLinuxOptions - spec.containers[].securityContext.seccompProfile - spec.containers[].securityContext.capabilities - spec.containers[].securityContext.readOnlyRootFilesystem - spec.containers[].securityContext.privileged - spec.containers[].securityContext.allowPrivilegeEscalation - spec.containers[].securityContext.procMount - spec.containers[].securityContext.runAsUser - spec.containers[*].securityContext.runAsGroup This is an alpha field and requires the IdentifyPodOS feature

      hostUsers
      bool
      (Optional)

      Use the host’s user namespace. Optional: Default to true. If set to true or not present, the pod will be run in the host user namespace, useful for when the pod needs a feature only available to the host user namespace, such as loading a kernel module with CAP_SYS_MODULE. When set to false, a new userns is created for the pod. Setting false is useful for mitigating container breakout vulnerabilities even allowing users to run their containers as root without actually having root privileges on the host. This field is alpha-level and is only honored by servers that enable the UserNamespacesSupport feature.

      schedulingGates
      []Kubernetes core/v1.PodSchedulingGate
      (Optional)

      SchedulingGates is an opaque list of values that if specified will block scheduling the pod. If schedulingGates is not empty, the pod will stay in the SchedulingGated state and the scheduler will not attempt to schedule the pod.

      SchedulingGates can only be set at pod creation time, and be removed only afterwards.

      This is a beta feature enabled by the PodSchedulingReadiness feature gate.

      resourceClaims
      []Kubernetes core/v1.PodResourceClaim
      (Optional)

      ResourceClaims defines which ResourceClaims must be allocated and reserved before the Pod is allowed to start. The resources will be made available to those containers which consume them by name.

      This is an alpha field and requires enabling the DynamicResourceAllocation feature gate.

      This field is immutable.
