If endpoint and region are provided, endpoint is used. If the region information is not available in the existing maps, following sources are checked in order: 1. Regions Configuration File at ~/.oci/regions-config.json 2. Region Metadata Environment variable 3. Instance Metadata Service Lookup from Instance Metadata Service is disabled by default. To enable, call enable_instance_metadata_service() The region metadata schema is: { "realmKey" : string, "realmDomainComponent" : string, "regionKey" : string, "regionIdentifier" : string } For example, for the Sydney OC1 region, the schema would be filled out as follows: { "realmKey" : "OC1", "realmDomainComponent" : "oraclecloud.com", "regionKey" : "SYD", "regionIdentifier" : "ap-sydney-1" } If the region still cannot be resolved, we fall back to OC1 realm. If alloy mode is enabled, and OCI_ALLOY_REGION_COEXIST is not set, only the alloy regions are available. If you want to access OCI and alloy regions at the same time, please set OCI_ALLOY_REGION_COEXIST to True. Fallback to OC1 realm is not available when OCI_ALLOY_REGION_COEXIST is not set. z+Must supply either a region or an endpoint.)� ValueError�_format_endpointr r r r � _endpoint_for)�servicer �endpoint�service_endpoint_template�endpoint_service_namer r r � endpoint_for� s #r. c C s t �d� ttj� d S )Nz*Disabling region metadata lookup from IMDS�r! r" �_set_source_has_been_readr r r r r r � skip_instance_metadata_service� s r1 c C s t �d� ttjd� d S )Nz)Enabling region metadata lookup from IMDSFr/ r r r r � enable_instance_metadata_service� s r2 c C s t s t� t| � dS )z� This method is called from the alloy_config.py file to register an alloy region.
