Armada API

Armada exposes an API via gRPC or REST.

gRPC

The API is defined in /pkg/api folder with *.proto files as source for all generated code.

Folder /pkg/api also contains generated clients and together with helper methods from /pkg/client provides a convenient way to call Armada API from go code. See armadactl code for examples.

Public API

Following subset of API defined in /pkg/api is intended for public use.

api.Submit (definition)

/api.Submit/SubmitJobs - submitting jobs to be run

/api.Submit/CancelJobs - cancel jobs

/api.Submit/CreateQueue - create or update existing queue

/api.Submit/DeleteQueue - remove queue

/api.Submit/GetQueueInfo - get information about active queue jobs

api.Event (definition)

/api.Event/GetJobSetEvents - read events of jobs running under particular JobSet

Internal

There are additional API methods defined in proto specifications, which are used by Armada executor and not intended to be used by external users. This API can change in any version.

REST

The REST API only exposes the public part of the gRPC API and it is implemented using grpc-gateway (https://github.com/grpc-ecosystem/grpc-gateway).

Swagger json specification can be found here and is also served by armada under my.armada.deployment/api/swagger.json

Authentication

Both gRPC and REST API support the same set of authentication methods. In the case of gRPC all authentication methods uses authorization key in grpc metadata. The REST API use standard http Authorization header (which is translated by grpc-gateway to authorization metadata).

See helm chart documentation for different server authentication schemes setup.

No Auth

For testing, armada can be configured to accept no authentication. All operations will use user anonymous in this case.

OpenId Authentication

When server is configured with OpenID, it will accept authorization header or metadata in the form Bearer {oauth_token}.

Basic Authentication

For basic authentication API accepts standard authorization header or metadata in the form basic {base64(user:password)}.

Kerberos

For Kerberos authentication API accepts the same authorization metadata for gRPC as standard Kerberos http SPNEGO authorization headers, the API responds with WWW-Authenticate header or metadata.
