Connecting to Scalr via API V2 and Python

[Ron Rabakukk]

I have been successfully using the earlier version of the API and want to upgrade to the new version. I am trying this example (https://github.com/scalr-tutorials/apiv2-examples/tree/master/python) and also trying to connect via the API Explorer like on this page (https://api-explorer.scalr.com/user/images/get.html). I have verified that I set it up right in the /etc/scalr-server/scalr-server.rb file:

app[:configuration] = { 
  :scalr => {

    # Enable the system API 
    :system => { 
        :api => { 
            :enabled => true, 
            :allowed_origins => '*' 
        }, 
    },

and I have my credentials set properly. But when I try to run a query to get a list of images (like on the API explorer page I listed above) I get the following response:

{ 
  "meta": { 
    "requestId": "549b445c-7a76-449f-98ce-b3daff2d884f", 
    "stringToSign": "GET\n2016-11-28T16:53:58.239Z\n/api/v1beta0/user/1/images/\n\n" 
  }, 
  "errors": [ 
    { 
      "code": "InternalServerError", 
      "message": "Server Error" 
    } 
  ] 
}

I get the same thing when I try to run the example in Git, I get an "InternalServerError".

Any ideas what this could be?

Thanks!

What version of Scalr you have?

Thanks,
Igor

Images management was added in 7.X version which is available only as
Enterprise Edition. You need to wait for the next OS release.

I only picked to query images as a test. What is available in the version we are using? Thanks.

Is there any documentation anywhere on what is available for the API v2 with the version that we have? Thanks.

Hi Ron,

Although this list is not specific to API, you can find all changes and additions for each version of Scalr in our Release Notes page.

Thanks.

So anytime I get the response:

"errors": [ { "code": "InternalServerError", "message": "Server Error" } ]

that means it isn't supported in our version? It seems that is the error I get on everything I'd like to use out of the APIv2 Explorer.

Hi Ron,

This may actually mean that there is an error preventing proper API communication on your Scalr server.  Did you run the reconfigure command after enabling and setting allowed origin in your scalr-server.rb?  If so, can you archive and attach your Scalr server logs from /opt/scalr-server/var/logs ?  We may find errors related to this in your php logs.

Many thanks,

Yes, I did run the reconfigure command. I even reset enabled to false, ran the reconfigure and verified that the error I got was that the API was not enabled, then set it back to true and ran reconfigure. Attached is a tar of the logs. Thanks for looking.

Hi Ron,

I am seeing the following repeated in your web.app.error.log:

[Mon Nov 28 20:25:38.390632 2016] [:error] [pid 30236] [client 127.0.0.1:40676] PHP Fatal error: Uncaught exception 'RuntimeException' with message 'Both LDAP user and password must be provided in the config for the scalr.connections.ldap parameter's bag.' in /opt/scalr-server/embedded/scalr/app/src/Scalr/Api/Rest/ApiApplication.php:670\nStack trace:\n #0 [internal function]: Scalr\\Api\\Rest\\ApiApplication->authenticationMiddleware(Object(Scalr\\Api\\Rest\\Routing\\Route))\n  #1 /opt/scalr-server/embedded/scalr/app/src/Scalr/Api/Rest/Routing/Route.php(457): call_user_func_array(Array, Array)\n  #2 /opt/scalr-server/embedded/scalr/app/src/Scalr/Api/Rest/Application.php(348): Scalr\\Api\\Rest\\Routing\\Route->dispatch()\n  #3 /opt/scalr-server/embedded/scalr/app/src/Scalr/Api/Rest/Application.php(275): Scalr\\Api\\Rest\\Application->call()\n  #4 /opt/scalr-server/embedded/scalr/app/www/restapi.php(39): Scalr\\Api\\Rest\\Application->run()\n  #5 {main}, referer: https://api-explorer.scalr.com/user/roles/get_roleId.html

Can you verify your scalr-server.rb has these values configured correctly?  This is addressed in our LDAP config documentation under the header for "API Key Authentication when using LDAP."

Many thanks,
Wm. Marc O'Brien
Scalr Technical Support

[Ron Rabakukk]

Thanks for that. I do not have a scalr.connections.ldap.user, or a scalr.connections.ldap.pass defined there though LDAP has been working fine for us to log into the client, etc. The documentation says that these are needed "if you intend to use APIv1 with LDAP auth."  I am adding them in, running the reconfigure, and trying again. Thanks.

It looks like that worked. I was able to run the example and am able to get data back from the API Explorer. Thanks for your help!
