Experiment REST API

Create Experiment (Using Anonymous/Embedded Environment)​

POST /api/v1/experiment

Parameters​

Put ExperimentSpec in request body.

ExperimentSpec​

Field NameTypeDescription
metaExperimentMetaMeta data of the experiment template.
environmentEnvironmentSpecEnvironment of the experiment template.
specMap<String, ExperimentTaskSpec>Spec of pods.
codeCodeSpecExperiment codespec.

ExperimentMeta​

Field NameTypeDescription
nameStringExperiment name.
namespaceStringExperiment namespace.
frameworkStringExperiemnt framework.
cmdStringCommand.
envVarsMap<String, String>Environmental variables.
