Support OCI Vault integration using Instance Principals

[anilmoris]

I’m trying to configure the Oracle DB Observability Exporter (v1.6.0) to retrieve the database password from OCI Vault using Instance Principals.

I am passing
OCI_VAULT_ID
OCI_VAULT_SECRET_NAME

I am seeing this error

time=2025-05-02T11:13:16.538Z level=INFO  source=main.go:75 msg="OCI_VAULT_ID env var is present so using OCI Vault" vaultOCID=ocid1.vault.oc1.phx...
2025/05/02 11:13:16 can not create client, bad configuration: did not find a proper configuration for tenancy

Expected behavior:
The exporter should detect and use the instance principal (no local config file), retrieve the secret from OCI Vault, and connect to the database without requiring a wallet or ~/.oci/config.

Actual current behavior:
It fails with did not find a proper configuration for tenancy even though instance principal is enabled.

a local ~/.oci/config is not needed when using Instance Principals.
