| 5 | ``openrc`` configures login credentials suitable for use with the |
| 6 | OpenStack command-line tools. ``openrc`` sources ``stackrc`` at the |
| 7 | beginning (which in turn sources the ``localrc`` setion of |
| 8 | ``local.conf``) in order to pick up ``HOST_IP`` and/or ``SERVICE_HOST`` |
| 9 | to use in the endpoints. The values shown below are the default values. |
| 10 | |
| 11 | OS\_TENANT\_NAME |
| 12 | The introduction of Keystone to the OpenStack ecosystem has |
| 13 | standardized the term *tenant* as the entity that owns resources. In |
| 14 | some places references still exist to the original Nova term |
| 15 | *project* for this use. Also, *tenant\_name* is preferred to |
| 16 | *tenant\_id*. |

| 20 | OS_TENANT_NAME=demo |
| 21 | |
| 22 | OS\_USERNAME |
| 23 | In addition to the owning entity (tenant), Nova stores the entity |
| 24 | performing the action as the *user*. |
| 25 | |

| 28 | OS_USERNAME=demo |
| 29 | |
| 30 | OS\_PASSWORD |
| 31 | With Keystone you pass the keystone password instead of an api key. |
| 32 | Recent versions of novaclient use OS\_PASSWORD instead of |
| 33 | NOVA\_API\_KEYs or NOVA\_PASSWORD. |
| 34 | |
| 35 | :: |
| 36 | |
| 37 | OS_PASSWORD=secrete |
| 38 | |
| 39 | HOST\_IP, SERVICE\_HOST |
| 40 | Set API endpoint host using ``HOST_IP``. ``SERVICE_HOST`` may also |
| 41 | be used to specify the endpoint, which is convenient for some |
| 42 | ``localrc`` configurations. Typically, ``HOST_IP`` is set in the |
| 43 | ``localrc`` section. |
| 44 | |
| 45 | :: |
| 46 | |
| 47 | HOST_IP=127.0.0.1 |
| 48 | SERVICE_HOST=$HOST_IP |
| 49 | |
| 50 | OS\_AUTH\_URL |
| 51 | Authenticating against an OpenStack cloud using Keystone returns a |
| 52 | *Token* and *Service Catalog*. The catalog contains the endpoints |
| 53 | for all services the user/tenant has access to - including Nova, |
| 54 | Glance, Keystone and Swift. |
| 55 | |
| 56 | :: |
| 57 | |
| 58 | OS_AUTH_URL=http://$SERVICE_HOST:5000/v2.0 |
| 59 | |
| 60 | GLANCE\_HOST |
| 61 | Some exercises call Glance directly. On a single-node installation, |
| 62 | Glance should be listening on ``HOST_IP``. If its running elsewhere |
| 63 | it can be set here. |
| 64 | |
| 65 | :: |
| 66 | |
| 67 | GLANCE_HOST=$HOST_IP |
| 68 | |
| 69 | KEYSTONECLIENT\_DEBUG, NOVACLIENT\_DEBUG |
| 70 | Set command-line client log level to ``DEBUG``. These are commented |
| 71 | out by default. |
| 72 | |
| 73 | :: |
| 74 | |
| 75 | # export KEYSTONECLIENT_DEBUG=1 |
| 76 | # export NOVACLIENT_DEBUG=1 |
