# This file is part of cloud-init. See LICENSE file for license information. """ Feature flags are used as a way to easily toggle configuration **at build time**. They are provided to accommodate feature deprecation and downstream configuration changes. Currently used upstream values for feature flags are set in ``cloudinit/features.py``. Overrides to these values (typically via quilt patch) can be placed in a file called ``feature_overrides.py`` in the same directory. Any value set in ``feature_overrides.py`` will override the original value set in ``features.py``. Each flag should include a short comment regarding the reason for the flag and intended lifetime. Tests are required for new feature flags, and tests must verify all valid states of a flag, not just the default state. """ ERROR_ON_USER_DATA_FAILURE = True """ If there is a failure in obtaining user data (i.e., #include or decompress fails) and ``ERROR_ON_USER_DATA_FAILURE`` is ``False``, cloud-init will log a warning and proceed. If it is ``True``, cloud-init will instead raise an exception. As of 20.3, ``ERROR_ON_USER_DATA_FAILURE`` is ``True``. (This flag can be removed after Focal is no longer supported.) """ ALLOW_EC2_MIRRORS_ON_NON_AWS_INSTANCE_TYPES = False """ When configuring apt mirrors, if ``ALLOW_EC2_MIRRORS_ON_NON_AWS_INSTANCE_TYPES`` is ``True`` cloud-init will detect that a datasource's ``availability_zone`` property looks like an EC2 availability zone and set the ``ec2_region`` variable when generating mirror URLs; this can lead to incorrect mirrors being configured in clouds whose AZs follow EC2's naming pattern. As of 20.3, ``ALLOW_EC2_MIRRORS_ON_NON_AWS_INSTANCE_TYPES`` is ``False`` so we no longer include ``ec2_region`` in mirror determination on non-AWS cloud platforms. If the old behavior is desired, users can provide the appropriate mirrors via :py:mod:`apt: <cloudinit.config.cc_apt_configure>` directives in cloud-config.
