A developer on the water-meter telemetry service runs docker login against OCIR and keeps getting authentication failures after pasting an API signing key as the password. What should they use instead?
Select an answer to reveal the explanation.
Short Explanation
docker login to OCIR wants an IAM auth token as the password. An API signing key is for the OCI SDK/CLI handshake, not Docker’s—mixing them is the classic failed login.
Full Explanation
Authentication for the Docker CLI against OCIR uses an IAM auth token as the password. API signing keys authenticate the OCI SDK and OCI CLI, not the Docker registry handshake. Using a signing key, tenancy OCID, Vault key ID, or compartment name as the Docker password produces failed logins.
