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
