ExperimentSpec

ExperimentSpec defines the desired state of Experiment

Field Description Scheme Required
replicas Replicas is the number of trials to execute concurrently, defaults to 1 *int32 false
optimization Optimization defines additional configuration for the optimization []Optimization false
parameters Parameters defines the search space for the experiment []Parameter true
constraints Constraints defines restrictions on the parameter domain for the experiment []Constraint false
metrics Metrics defines the outcomes for the experiment []Metric true
patches Patches is a sequence of templates written against the experiment parameters that will be used to put the cluster into the desired state []PatchTemplate false
namespaceSelector NamespaceSelector is used to locate existing namespaces for trials *LabelSelector false
namespaceTemplate NamespaceTemplate can be specified to create new namespaces for trials; if specified created namespaces must be matched by the namespace selector *NamespaceTemplateSpec false
selector Selector locates trial resources that are part of this experiment *LabelSelector false
template Template for creating a new trial. The resulting trial must be matched by Selector. The template can provide an initial namespace, however other namespaces (matched by NamespaceSelector) will be used if the effective replica count is more then one TrialTemplateSpec false

Parameter

Parameter represents the domain of a single component of the experiment search space

Field Description Scheme Required
name The name of the parameter string true
baseline The baseline value for this parameter. *intstr.IntOrString false

PatchReadinessGate

PatchReadinessGate contains a reference to a condition

Field Description Scheme Required
conditionType ConditionType refers to a condition in the patched target’s condition list string true

Back to TOC

PatchTemplate

PatchTemplate defines a target resource and a patch template to apply

Field Description Scheme Required
type The patch type, one of: strategic|merge|json, default: strategic PatchType false
patch A Go Template that evaluates to valid patch string true
targetRef Direct reference to the object the patch should be applied to *ObjectReference false
readinessGates ReadinessGates will be evaluated for patch target readiness. A patch target is ready if all conditions specified in the readiness gates have a status equal to “True”. If no readiness gates are specified, some target types may have default gates assigned to them. Some condition checks may result in errors, e.g. a condition type of “Ready” is not allowed for a ConfigMap. Condition types starting with “redskyops.dev/” may not appear in the patched target’s condition list, but are still evaluated against the resource’s state. []PatchReadinessGate false
