Notes

Note

  • Ansible uses the cs library’s configuration method if credentials are not provided by the arguments api_url, api_key, api_secret. Configuration is read from several locations, in the following order. The CLOUDSTACK_ENDPOINT, CLOUDSTACK_KEY, CLOUDSTACK_SECRET and CLOUDSTACK_METHOD. CLOUDSTACK_TIMEOUT environment variables. A CLOUDSTACK_CONFIG environment variable pointing to an .ini file. A cloudstack.ini file in the current working directory. A .cloudstack.ini file in the users home directory. Optionally multiple credentials and endpoints can be specified using ini sections in cloudstack.ini. Use the argument api_region to select the section name, default section is cloudstack. See https://github.com/exoscale/cs for more information.
  • A detailed guide about cloudstack modules can be found in the CloudStack Cloud Guide.
  • This module supports check mode.
