Tech tip: Increase openstack project quota from command line

1. List the keystone tenants and search for the required tenant

keystone tenant-list |grep <tenantname>

 Note the id of the tenant being displayed. You need to use this id in the next command

2. Get quota details of the tenant using the following command

nova-manage project quota <tenantid>




You will be getting output similar to this

Quota                                Limit      In Use     Reserved
metadata_items                       128        0          0
injected_file_content_bytes          10240      0          0
ram                                  51200      0          0
floating_ips                         10         0          0
security_group_rules                 20         0          0
instances                            10         0          0
key_pairs                            100        0          0
injected_files                       5          0          0
cores                                20         0          0
fixed_ips                            unlimited  0          0
injected_file_path_bytes             255        0          0
security_groups                      10         0          0


3. Update value of the key, depending on which item you want to update. For eg, if you want to increase the number of instances from 10 to 20, give the following command

nova-manage project quota <tenantid> --key instances --value 20

4.Now run the "nova-manage quota <tenantid> " command to see if the quota is updated
