Hello, I have been testing rancher with openstack and I could successfully launch rancher host on openstack through rancher UI. However, I’m unable to launch a rancher host when tried it through the rancher API.  
Below is the request I tried:

HTTP Request:  
HTTP/1.1 POST /v1/projects/1a5/openstackconfigs  
Host: x.x.x.x  
Accept: application/json  
Content-Type: application/json  
Content-Length: 319

{  
“authUrl”: “[http://x.x.x.x:5000/v2.0](http://x.x.x.x:5000/v2.0)”,  
“flavorName”: “custom.1.1.10”,  
“imageName”: “ubuntu”,  
“keypairName”: “adaikal\_ssh\_2”,  
“netName”: “public”,  
“password”: “\*\*\*\*\*”,  
“privateKeyFile”: “/.ssh/adaikal\_ssh\_2”,  
“region”: “RegionOne”,  
“secGroups”: “default”,  
“sshPort”: “22”,  
“sshUser”: “ubuntu”,  
“tenantName”: “demo”,  
“username”: “demo”,  
}

Posting the above JSON is giving the below error:

HTTP Response:

“actions”: { },  
“status”: 500,  
“code”: “Internal Server Error”,  
“message”: “Internal Server Error”,  
“detail”: null,  
}

And below is the error log I got from rancher server:

2016-03-28 10:24:02,545 ERROR [:] [] [] [] [p423436977-1224] [i.g.i.g.r.handler.ExceptionHandler] Exception in API for request [io.github.ibuildthecloud.gdapi.request.ApiRequest@79d65d63] java.lang.IllegalArgumentException: Class [class io.cattle.platform.docker.machine.api.addon.BaseMachineConfig] is not an instanceof UpdatableRecord

Could you please advise how to fix this?!

And I also have been wondering, while I configured the openstack-rancher host in rancher UI, it asked me a host name for the host but there is no key as “name” in the API, why so?

You want `POST /v1/projects/1a5/machines`… It takes an object that has the name (among other things), and a driver-specific config field for every driver where you populate any one of them (this is the body you’re currently sending).

The error handling in this situation is unfortunate, but `openstackConfig` is only used as an embedded object, so trying to use it as a collection should have just said 404 or 405.

Thank you Vincent, really appreciate your help.

I could post the JSON on /v1/projects/1a5/machines and the machine started to create but it got teared down because of the following error:

time=“2016-03-28T12:20:07Z” level=info msg=“stderr: Error setting machine configuration from flags provided: Authentication URL must be specified either using the environment variable OS\_AUTH\_URL or the CLI option --openstack-auth-url” resourceId=1ph26

As you can see from the below JSON, I provided the AUTH\_URL but yet it is asking to specify it.

{  
“authUrl”: “[http://x.x.x.x:5000/v2.0](http://x.x.x.x:5000/v2.0)”,  
“flavorName”: “custom.1.1.10”,  
“imageName”: “ubuntu”,  
“keypairName”: “adaikal\_ssh\_2”,  
“netName”: “public”,  
“password”: “\*\*\*\*\*”,  
“privateKeyFile”: “/.ssh/adaikal\_ssh\_2”,  
“region”: “RegionOne”,  
“secGroups”: “default”,  
“sshPort”: “22”,  
“sshUser”: “ubuntu”,  
“tenantName”: “demo”,  
“username”: “demo”,  
}

Could you please advise.

If you look just above that you can see the “Cmd slice:” which is the arguments passed to `docker-machine`. This whole API is just a thin wrapper around machine. I don’t have a running OpenStack setup handy but it seems to me that everything is getting passed through. There are 24 fields (+1 bool):

```auto
{
  "type": "machine",
  "name": "openstack",
  "openstackConfig": {
    "type": "openstackConfig",
    "activeTimeout": "1",
    "authUrl": "2",
    "availabilityZone": "3",
    "domainId": "4",
    "domainName": "5",
    "endpointType": "6",
    "flavorId": "7",
    "flavorName": "8",
    "floatingipPool": "9",
    "imageId": "10",
    "imageName": "11",
    "ipVersion": "12",
    "keypairName": "13",
    "netId": "14",
    "netName": "15",
    "password": "16",
    "novaNetwork": true,
    "privateKeyFile": "17",
    "region": "18",
    "secGroups": "19",
    "sshPort": "20",
    "sshUser": "21",
    "tenantId": "22",
    "tenantName": "23",
    "username": "24"
  }
}

```

Produces:

```auto
time="2016-03-28T16:47:07Z" level=info msg="Creating Machine" eventId=bde55603-826b-499d-9ab6-9484dbe4ec67 resourceId=1ph7

Vincent thanks again. I can provision the hosts through API now.
