Checking your environment

First, log into an Arvados VM instance (instructions for Webshell or Unix or Windows) or install the Arvados Command line SDK and Python SDK on your workstation.

Check that you are able to access the Arvados API server using arv user current. If it is able to access the API server, it will print out information about your account:

$ arv user current
{
 "href":"https://zzzzz.arvadosapi.com/arvados/v1/users/zzzzz-xioed-9z2p3pn12yqdaem",
 "kind":"arvados#user",
 "etag":"8u0xwb9f3otb2xx9hto4wyo03",
 "uuid":"zzzzz-tpzed-92d3kxnimy3d4e8",
 "owner_uuid":"zzzzz-tpqed-23iddeohxta2r59",
 "created_at":"2013-12-02T17:05:47Z",
 "modified_by_client_uuid":"zzzzz-xxfg8-owxa2oa2s33jyej",
 "modified_by_user_uuid":"zzzzz-tpqed-23iddeohxta2r59",
 "modified_at":"2013-12-02T17:07:08Z",
 "updated_at":"2013-12-05T19:51:08Z",
 "email":"you@example.com",
 "full_name":"Example User",
 "first_name":"Example",
 "last_name":"User",
 "identity_url":"https://www.google.com/accounts/o8/id?id=AItOawnhlZr-pQ_Ic2f2W22XaO02oL3avJ322k1",
 "is_active": true,
 "is_admin": false,
 "prefs":{}
}

However, if you receive the following message:

ARVADOS_API_HOST and ARVADOS_API_TOKEN need to be defined as environment variables

follow the instructions for getting an API token, and try arv user current again.
