I was looking through the API documentation of openstack for an API using which i can check if openstack has enough resources to instantiate an image. Quite frankly the API guide is quite overwhelming. Just wanted to know if anyone has come across any such documentation which could help me out of this pickle. Alternative pointers are also appreciated.
Thank you
Edit: Based on Albert V's response i tried the following:
curl -s -H "X-Auth-Token: $OS_AUTH_TOKEN" http://localhost:8774/v2/a6bc799ca8544b3f9a6698397fac92f7/os-quota-sets/c32f25d98f974c5a89e7c19cb7292da5/detail
But the ouput i am getting seems to be wrong, because the current usage is wrong and limits are also wrong:
{"quota_set": {"injected_file_content_bytes": {"reserved": 0, "limit": 10240, "in_use": 0}, "metadata_items": {"reserved": 0, "limit": 128, "in_use": 0}, "server_group_members": {"reserved": 0, "limit": 10, "in_use": 0}, "server_groups": {"reserved": 0, "limit": 10, "in_use": 0}, "ram": {"reserved": 0, "limit": 51200, "in_use": 0}, "floating_ips": {"reserved": 0, "limit": 23, "in_use": 0}, "key_pairs": {"reserved": 0, "limit": 100, "in_use": 0}, "id": "db3cceb48ecb4f028cbd7ec48e1e7fb0", "instances": {"reserved": 0, "limit": 10, "in_use": 0}, "security_group_rules": {"reserved": 0, "limit": 20, "in_use": 0}, "injected_files": {"reserved": 0, "limit": 5, "in_use": 0}, "cores": {"reserved": 0, "limit": 20, "in_use": 0}, "fixed_ips": {"reserved": 0, "limit": -1, "in_use": 0}, "injected_file_path_bytes": {"reserved": 0, "limit": 255, "in_use": 0}, "security_groups": {"reserved": 0, "limit": 10, "in_use": 0}}}
Below is a screenshot from the openstack dashboard regardin machine limits and usage summary: Openstack Limit Summary from Dashboard
