OCI Classic provides an EC2 lookalike metadata service. * The UUID provided in DMI data is not the same as the meta-data provided instance-id, but has an equivalent lifespan. * We do need to support upgrade from an instance that cloud-init identified as OpenStack. * Bare metal instances use iSCSI root, virtual machine instances do not. * Both bare metal and virtual machine instances provide a chassis-asset-tag of OracleCloud.com. � N)�Any�Dict�List� NamedTuple�Optional�Tuple)� atomic_helper�dmi�net�sources�util)� NetworkConfig)�cmdline� ephemeral�get_interfaces_by_mac�is_netfail_master)� wait_for_url�configure_secondary_nicsFzOracleCloud.comz&http://169.254.169.254/opc/v{version}/z+http://[fd00:c1::a9fe:a9fe]/opc/v{version}/z{path}/Z Authorizationz Bearer Oraclei(# c @ sB e Zd ZU eed< eeef ed< eeeef ed< eed< dS )�ReadOpcMetadataResponse�version� instance_data� vnics_data� imds_url_usedN) �__name__� __module__� __qualname__�int�__annotations__r �strr r � r r �F/usr/lib/python3.9/site-packages/cloudinit/sources/DataSourceOracle.pyr 4 s r c @ s e Zd ZdZed�dd�ZdS )� KlibcOracleNetworkConfigSourcez�Override super class to lower the applicability conditions.
