In order to work with an OpenStack cloud you first need to create a Connection to it using your credentials. A Connection can be created in 3 ways, using the class itself (see Connect), a file, or environment variables as illustrated below. The SDK uses os-client-config to handle the configuration.
Note
To get your credentials Download the OpenStack RC file.
To create a connection from a file you need a YAML file to contain the configuration.
clouds:
test_cloud:
region_name: RegionOne
auth:
auth_url: http://xxx.xxx.xxx.xxx:5000/v2.0/
username: demo
password: secrete
project_name: demo
example:
image_name: fedora-20.x86_64
flavor_name: m1.small
network_name: private
rackspace:
cloud: rackspace
auth:
username: joe
password: joes-password
project_name: 123123
region_name: IAD
To use a configuration file called clouds.yaml in one of the default locations:
call from_config(). The from_config function takes three optional arguments, such as cloud_name, which allows you to specify one set of cloud credentials in your clouds.yaml file. Additionally, cloud_config and options allow you to pass in configiration data you may have already received from os-client-config, as well as additional options that the os-client-config library may need.
Note
To enable logging, set debug=True in the Opts object.
To use a configuration file in a user defined location set the environment variable OS_CLIENT_CONFIG_FILE to the absolute path of a file.:
export OS_CLIENT_CONFIG_FILE=/path/to/my/config/my-clouds.yaml
and call from_config() with the cloud_name of the cloud configuration to use, .
Now that you can create a connection, continue with the User Guides for an OpenStack service.
