OCI Instance Principals Authentication

OCI Instance Principals Authentication

In OCI, one of the authentication mechanism is using "Instance Principals". Here we don't need to use a key to execute OCI CLI commands, instead of key we are allowing OCI Compute instance the permission to execute CLI commands.

In this video you can see the steps.

1. Get the OCID of the compute instance

2. Create a Dynamic group

3. Create a Policy

4. Validate the setup

5. Execute your CLI commands {oci os object put --bucket-name backup-bucket --file sc_laundry_db-202412181734507003.sql --auth instance_principal}
