Configuration file
------------------
The cloud deployment configuration schema has simple YAML/JSON format:
.. code-block:: yaml
cloud_management:
driver: devstack
args:
address: 192.168.1.240
auth:
username: stack
private_key_file: cloud_key
iface: enp0s8
power_managements:
- driver: libvirt
args:
connection_uri: qemu+ssh://ubuntu@10.0.1.50/system
By default, the library reads configuration from a file with one of
the following names: ``os-faults.{json,yaml,yml}``. The configuration
file is searched in one of default locations:
* current directory
* ~/.config/os-faults
* /etc/openstack
Also, the name of the configuration file can be specified in the
``OS_FAULTS_CONFIG`` environment variable::
$ export OS_FAULTS_CONFIG=/home/alex/my-os-faults-config.yaml
Execution
---------
Establish a connection to the cloud and verify it:
.. code-block:: python
import os_faults
cloud_management = os_faults.connect(config_filename='os-faults.yaml')
cloud_management.verify()
or via CLI::
$ os-faults verify -c os-faults.yaml
Make some destructive action:
.. code-block:: python
cloud_management.get_service(name='keystone').restart()
or via CLI::
$ os-inject-fault -c os-faults.yaml restart keystone service
