Create OpenStack client environment scripts¶

The previous section used a combination of environment variables and command options to interact with the Identity service via the openstack client. To increase efficiency of client operations, OpenStack supports simple client environment scripts also known as OpenRC files. These scripts typically contain common options for all clients, but also support unique options. For more information, see the OpenStack User Guide.

Creating the scripts¶

Create client environment scripts for the admin and demo projects and users. Future portions of this guide reference these scripts to load appropriate credentials for client operations.

Edit the admin-openrc.sh file and add the following content:

export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=admin
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3

Replace ADMIN_PASS with the password you chose for the admin user in the Identity service.

Edit the demo-openrc.sh file and add the following content:

export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=demo
export OS_TENANT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=DEMO_PASS
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3

Replace DEMO_PASS with the password you chose for the demo user in the Identity service.

Using the scripts¶

To run clients as a specific project and user, you can simply load the associated client environment script prior to running them. For example:

Load the admin-openrc.sh file to populate environment variables with the location of the Identity service and the admin project and user credentials:
```
$ source admin-openrc.sh
```

Request an authentication token:

$ openstack token issue
