We are currently setting up a private Cloud by using Heat in combination with Openstack. But we are struggling with the "AWS::ElasticLoadBalancing::LoadBalancer"-Resource when setting up a Loadbalancer with Heat because this Resource-Type has no User-Data and seems to use the F17-x86_64-cfntools-Image by default (can I change it?). Since we are behind a proxy and cfn-init starts trying to install some packages via yum (like haproxy) when Bootstrapping the Image we need to set a proxy before cfn-init starts. Is there any solution for this problem (except of patching the above Image while keeping its name unchanged)?
Thx!
