openrc - User Authentication SettingsΒΆ

openrc configures login credentials suitable for use with the OpenStack command-line tools. openrc sources stackrc at the beginning (which in turn sources the localrc setion of local.conf) in order to pick up HOST_IP and/or SERVICE_HOST to use in the endpoints. The values shown below are the default values.

OS_PROJECT_NAME (OS_TENANT_NAME)

Keystone has standardized the term project as the entity that owns resources. In some places references still exist to the previous term tenant for this use. Also, project_name is preferred to project_id. OS_TENANT_NAME remains supported for compatibility with older tools.

OS_PROJECT_NAME=demo
OS_USERNAME

In addition to the owning entity (project), OpenStack calls the entity performing the action user.

OS_USERNAME=demo
OS_PASSWORD

Keystone’s default authentication requires a password be provided. The usual cautions about putting passwords in environment variables apply, for most DevStack uses this may be an acceptable tradeoff.

OS_PASSWORD=secrete
HOST_IP, SERVICE_HOST

Set API endpoint host using HOST_IP. SERVICE_HOST may also be used to specify the endpoint, which is convenient for some local.conf configurations. Typically, HOST_IP is set in the localrc section.

HOST_IP=127.0.0.1
SERVICE_HOST=$HOST_IP
OS_AUTH_URL

Authenticating against an OpenStack cloud using Keystone returns a Token and Service Catalog. The catalog contains the endpoints for all services the user/tenant has access to - including Nova, Glance, Keystone and Swift.

OS_AUTH_URL=http://$SERVICE_HOST:5000/v2.0
KEYSTONECLIENT_DEBUG, NOVACLIENT_DEBUG

Set command-line client log level to DEBUG. These are commented out by default.

# export KEYSTONECLIENT_DEBUG=1
# export NOVACLIENT_DEBUG=1
