Connect From Config

In order to work with an OpenStack cloud you first need to create a ~openstack.connection.Connection to it using your credentials. A ~openstack.connection.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.

Create Connection From A File

Default Location

To create a connection from a file you need a YAML file to contain the configuration.

../../contributors/clouds.yaml

To use a configuration file called clouds.yaml in one of the default locations:

• Current Directory
• ~/.config/openstack
• /etc/openstack

call :py~openstack.connection.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.

../examples/connect.py

../examples/connect.py

Note

To enable logging, set debug=True in the Opts object.

User Defined Location

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 :py~openstack.connection.from_config with the cloud_name of the cloud configuration to use, .

Next

Now that you can create a connection, continue with the user_guides for an OpenStack service.
