Also, if try to imagine this in examples, then this can be represented like
that:
1) In case of an existent cloud, only an Endpoint should be added:
$ cat endpoint.jso
{
"auth_url": "http://example.com:5000/v2.0";,
"username": "admin",
"password": "secret",
"tenant_name": "demo"
}
$ rally endpoint add endpoint.json
The last command shows an endpoint_id of an added endpoint.
2.1) In case when OpenStack should be deployed:
$ rally deployment create --filename=deployment.json
2.2) Wait when a status has a proper value ("deploy->finished").
$ rally deployment list
In case of success deployment an endpoint is going to be automatically created
for the deployment:
$ rally endpoint list
3) To start a task an endpoint_id is required. There is one endpoint after (1)
or (2.2) step, use it:
$ rally task start --endpoint-id=<endpoint_id> --task task.json
