Please provide a simple method to obtain the instance metadata for the instance on which the SDK is being used

[ghost]

I know it's relatively simple to fetch http://169.254.169.254/opc/v1/instance/ and pass it through a json parser to get the metadata object. having this functionality in the SDK, where you're already doing these types of operations, removes a level of code duplication (and removes one more bit of tedious coding that everyone has to do).

hi @jearls, thanks for submitting the request. I am wondering what's your use cases for using metadata service? If you are trying to use InstanceAuth, the 'InstancePrincipalsSecurityTokenSigner' already handle that.

[darkfoxprime]

The InstancePrincipalsSecurityTokenSigner only provides the region short name from the metadata, and the tenancy information from the certificate. It does not provide the canonical region name, does not provide the instance id and compartment id, the tags, any custom metadata that's been defined, etc.

Hi, all the metadata is in the instance object, region is in short version, but you can query the list_regions to get the full name, see example below:

import oci

signer = oci.auth.signers.InstancePrincipalsSecurityTokenSigner() config = {'region': signer.region, 'tenancy': signer.tenancy_id}

instance_id = "ocid1.instance.oc1.iad.abuwcljsd27ddpfvlq3boailo2cgrd27bgat7v4e53mk4d5zb4z2d33loohq"

compute_client = oci.core.ComputeClient(config, signer=signer) compute_meta = compute_client.get_instance(instance_id).data

identity_client = oci.identity.IdentityClient(config, signer=signer) regions = identity_client.list_regions().data

region = [k.name for k in regions if k.key == compute_meta.region.upper()][0]

compute_meta region

@adizohar your method requires that you know the instance id on which you are running. to get that, you need to access the metadata service. thus my original request - to provide a utility function that fetches the instance metadata from the metadata service, rather than each person who uses this library needing to do the same code on their own. (utility function or other standardized mechanism for such access)

[adizohar]

For the SDK you need authenticate, either by instance principles, delegation token or apikey You cannot get data without it (for security)

If you want the metadata When running on the host, use the request package and call the metadata url

I don’t understand what exactly the issue ? Please give an example what exactly you need and the use case

[dldinternet]

Simple way to visualize the ask

metadata = oci.core.ComputeInstanceMetadata() compartment_id = metadata['compartmentId']

I came here looking for the same, but the comment from @adizohar realize I could achieve this with:

import requests
import json

headers = {'Authorization': 'Bearer Oracle'}
r = requests.get('http://169.254.169.254/opc/v2/instance/', headers=headers)
instance=r.json()['id']
