Authentication

An OpenStack Keystone access token is needed for the routes that need authentication. In order to generate this token, a Keystone user and a project associated to this user are necessary.

1. Create a project on Openstack Keystone.
2. Associate project to a user or group.
3. The token can be obtained in two ways:

Get Keystone Token

$ export TOKEN="$(curl --silent -u grouadmin:grou 127.0.0.1:8080/token/grou | jq -r .token)"

or

$ export TOKEN="$(openstack token issue -f value -c id)"

> ${PROJECT} is the previously registered project on OpenStack Keystone.
 ${TOKEN} is the temporary access token provided by OpenStack Keystone to the corresponding ${PROJECT}.


### Alternative way of getting access token (using openstack-client)

In the following example, the access token is obtained through the [openstack-client](https://pypi.python.org/pypi/python-openstackclient).

$ TOKEN=$(openstack --os-auth-url http://k1:5000/v3 \ --os-username ${login} \ --os-password ${pass} \ --os-domain-name grou \ --os-project-name ${PROJECT} \ token issue -f value -c id) ```
