OpenStorage SDK

Introduction

Welcome to the OpenStorage SDK documentation. Here you will find the API functions, examples, and references to multiple client libraries which can communicate with an OpenStorage server.

Quick Example

Here is a quick example of how to get cluster information from an OpenStorage server. In this example we will be using the mock SDK container as the server. First let's start the container by running the following command:

$ docker run --rm --name sdk -d -p 9100:9100 -p 9110:9110 openstorage/mock-sdk-server

This container starts a tiny, in-memory OpenStorage SDK server able to be used for development. More information can be found in the Tutorial.

Now we can send requests from the command line. To send requests to the gRPC server, we will use Polyglot 1.x.x as the gRPC client. To send requests to the gRPC REST Gateway, we will be sending the same request as Polyglot, but using curl instead:

gRPC
REST
$ wget https://github.com/grpc-ecosystem/polyglot/releases/download/v1.6.0/polyglot.jar
$ echo {} | java -jar polyglot.jar \
  --command=call \
  --endpoint=localhost:9100 \
  --full_method=openstorage.api.OpenStorageCluster/InspectCurrent
$ curl -X GET "http://localhost:9110/v1/clusters/inspectcurrent" \
     -H "accept: application/json" \
	 -H "Content-Type: application/json" \
	 -d "{}"

Results in:

{
  "cluster": {
    "status": "STATUS_OK",
    "id": "mock"
  }
}

The mock-sdk-server container also comes with a full Swagger UI located at http://localhost:9110/swagger-ui/.
