Summary

Tag: RunService

Operation Description
GET /apis/v1beta1/runs

Finds all runs.
POST /apis/v1beta1/runs

Creates a new run.
DELETE /apis/v1beta1/runs/{id}

Deletes a run.
POST /apis/v1beta1/runs/{id}:archive

Archives a run.
POST /apis/v1beta1/runs/{id}:unarchive

Restores an archived run.
GET /apis/v1beta1/runs/{run_id}

Finds a specific run by ID.
GET /apis/v1beta1/runs/{run_id}/nodes/{node_id}/artifacts/{artifact_name}:read

Finds a run's artifact data.
POST /apis/v1beta1/runs/{run_id}/retry

Re-initiates a failed or terminated run.
POST /apis/v1beta1/runs/{run_id}/terminate

Terminates an active run.
POST /apis/v1beta1/runs/{run_id}:reportMetrics

ReportRunMetrics reports metrics of a run. Each metric is reported in its own transaction, so this API accepts partial failures. Metric can be uniquely identified by (run_id, node_id, name). Duplicate reporting will be ignored by the API. First reporting wins.

Tag: JobService

Operation Description
GET /apis/v1beta1/jobs

Finds all jobs.
POST /apis/v1beta1/jobs

Creates a new job.
GET /apis/v1beta1/jobs/{id}

Finds a specific job by ID.
DELETE /apis/v1beta1/jobs/{id}

Deletes a job.
POST /apis/v1beta1/jobs/{id}/disable

Stops a job and all its associated runs. The job is not deleted.
POST /apis/v1beta1/jobs/{id}/enable

Restarts a job that was previously stopped. All runs associated with the job will continue.

Tag: PipelineService

Operation Description
GET /apis/v1beta1/pipeline_versions

Lists all pipeline versions of a given pipeline.
POST /apis/v1beta1/pipeline_versions

Adds a pipeline version to the specified pipeline.
GET /apis/v1beta1/pipeline_versions/{version_id}

Gets a pipeline version by pipeline version ID.
DELETE /apis/v1beta1/pipeline_versions/{version_id}

Deletes a pipeline version by pipeline version ID. If the deleted pipeline version is the default pipeline version, the pipeline's default version changes to the pipeline's most recent pipeline version. If there are no remaining pipeline versions, the pipeline will have no default version. Examines the run_service_api.ipynb notebook to learn more about creating a run using a pipeline version (https://github.com/kubeflow/pipelines/blob/master/tools/benchmarks/run_service_api.ipynb).

protobufAny: object

Any contains an arbitrary serialized protocol buffer message along with a URL that describes the type of the serialized message.

Protobuf library provides support to pack/unpack Any values in the form of utility functions or additional generated methods of the Any type.

Example 1: Pack and unpack a message in C++.

Foo foo = ...;
Any any;
any.PackFrom(foo);
...
if (any.UnpackTo(&foo)) {
  ...
}

Example 2: Pack and unpack a message in Java.

Foo foo = ...;
Any any = Any.pack(foo);
...
if (any.is(Foo.class)) {
  foo = any.unpack(Foo.class);
}

Example 3: Pack and unpack a message in Python.

foo = Foo(...)
any = Any()
any.Pack(foo)
...
if any.Is(Foo.DESCRIPTOR):
  any.Unpack(foo)
  ...

Example 4: Pack and unpack a message in Go

 foo := &pb.Foo{...}
 any, err := ptypes.MarshalAny(foo)
 ...
 foo := &pb.Foo{}
 if err := ptypes.UnmarshalAny(any, foo); err != nil {
   ...
 }

The pack methods provided by protobuf library will by default use 'type.googleapis.com/full.type.name' as the type URL and the unpack methods only use the fully qualified type name after the last '/' in the type URL, for example "foo.bar.com/x/y.z" will yield type name "y.z".

JSON

The JSON representation of an Any value uses the regular representation of the deserialized, embedded message, with an additional field @type which contains the type URL. Example:

package google.profile;
message Person {
  string first_name = 1;
  string last_name = 2;
}

                            {
  "@type": "type.googleapis.com/google.profile.Person",
  "firstName": <string>,
  "lastName": <string>
}

If the embedded message type is well-known and has a custom JSON representation, that representation will be embedded adding a field value which holds the custom JSON in addition to the @type field. Example (for message [google.protobuf.Duration][]):

{
  "@type": "type.googleapis.com/google.protobuf.Duration",
  "value": "1.212s"
}
type_url: string

A URL/resource name that uniquely identifies the type of the serialized protocol buffer message. The last segment of the URL's path must represent the fully qualified name of the type (as in path/google.protobuf.Duration). The name should be in a canonical form (e.g., leading "." is not accepted).

In practice, teams usually precompile into the binary all types that they expect it to use in the context of Any. However, for URLs which use the scheme http, https, or no scheme, one can optionally set up a type server that maps type URLs to message definitions as follows:

  • If no scheme is provided, https is assumed.
  • An HTTP GET on the URL must yield a [google.protobuf.Type][] value in binary format, or produce an error.
  • Applications are allowed to cache lookup results based on the URL, or have them precompiled into a binary to avoid any lookup. Therefore, binary compatibility needs to be preserved on changes to types. (Use versioned type names to manage breaking changes.)

Note: this functionality is not currently available in the official protobuf release, and it is not used for type URLs beginning with type.googleapis.com.

Schemes other than http, https (or the empty scheme) might be used with implementation specific semantics.

value: string (byte)

Must be a valid serialized protocol buffer of the above specified type.
