What's the proper way to make our application running on instances able to access the OpenStack component API endpoints, say, the swift API for object storage? Can't think of a way except for setting second quantum L3 agents on second external network interface shown in http://docs.openstack.org/trunk/openstack-network/admin/content/adv_cfg_l3_agent_multi_extnet.html

Hi tcheung ,

Will the VM s have access to Public API endpoints ? I tried to run curl command from a VM instance to compute API public endpoint but it its resulting in 'cannot connect error'. Is there some configuration to be made to allow VM s to access API endpoints? I am working on Havana version of OpenStack

Thanks,

Could you please explain what exactly the problem is? Why cant you reach the api endpoint from the instance?

For example, I have 3 nodes: Compute node, Network node and Controller node. Their management IP is in 10.10.10.0/24 VMs running on compute node is in virtual network 192.168.100.0/24 and br_ex of network node is in 192.168.0.0/24 How can VM access OpenStack API endpoint on 10.10.10.0/24?

Why don't you configure public endpoints?

Public endpoint is one of the choices, but it may involves setting on external switch so request from VM and reach these public endpoints. Do you think public endpoint is the only choice?
