Marios Andreou commented on DTACLOUD-330:
-----------------------------------------
Not sure why this ticket is still open - as far as I can see the issue is
addressed and resolved.
This ticket is specific to Openstack driver - because for that driver we need
credentials even for /api entry point. Conductor needs to be able to tell from:
DeltaCloud.new(nil, nil, "http://localhost:3001/api";)
whether the provider running @ "http://localhost:3001/api"; is valid or not.
For all other drivers this call will be silent, meaning that 'yes, the
deltacloud server running at the url is running with a valid driver'. For
Openstack however it (previous to the fix pushed above - see my comment [
https://issues.apache.org/jira/browse/DTACLOUD-330?focusedCommentId=13464561&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13464561
] ) was not possible to do this because Openstack needed creds even for the
/api. Which was producing a Deltacloud::ExceptionHandler::BackendError -
Unhandled exception or status code (Must supply a :username):
Now however, and specifically for the Openstack driver, Deltacloud will respond
with '401' status code. This tells conductor that 'yes, this is a valid
provider'. On the client side you get a DeltaCloud::HTTPError::Unauthorized
exception:
1 require 'rubygems'
2 require 'deltacloud'
3
4 begin
5 client = DeltaCloud.new(nil, nil, "http://localhost:3001/api";)
6 rescue DeltaCloud::HTTPError::Unauthorized => e
7 puts "valid"
8 end
Jan - can you please tell us if this addresses your issue?
thanks, marios

> Conductor keeps providers and provider accounts separately. This means that
> at first step a user adds a provider (ec2, rhevm, openstack), then he can add
> multiple accounts for this provider.
> When adding a provider, Conductor checks if the provider is valid by doing dc

> DeltaCloud.new(nil, nil, url)
> The problem is that this call always fails for Openstack driver with
> Deltacloud::ExceptionHandler::BackendError - Unhandled exception or status
