Redis error: ERR AUTH <password> called without any password configured in Harbor v1.15.1 (registry container logs)

[charger251]

Description

We are encountering an issue in Harbor v1.15.1 where the registry container logs the following error related to Redis authentication, even though no password is set for Redis and Sentinel:

level=error msg="redis: error connecting: ERR AUTH <password> called without any password configured for the default user. Are you sure your configuration is correct?" 
go.version=go1.22.6 
instance.id=73b0384e-4cc8-4956-8ee5-09fb5a624471 
redis.connect.duration=1.083452ms 
service=registry 
version=v2.8.3.m

Details:

• Harbor Version: v1.15.1
• Redis Configuration: No password set for Redis and Sentinel.
• Components:
  • core: Working without errors.
  • jobservice: Working without errors.
  • redis: No password is configured.
  • registry: Logs the Redis authentication error described above.

Despite the Redis authentication error in the registry container logs, the core and jobservice components are operating without issues. It seems the registry service is attempting to authenticate with Redis, even though no password is configured.

Steps to Reproduce:

1. Deploy Harbor v1.15.1 using the official Helm chart.
2. Ensure that Redis and Sentinel are configured without any passwords.
3. Check the logs of the registry container for Redis authentication errors.

Expected Behavior:

The registry should connect to Redis without attempting authentication if no password is configured.

Observed Behavior:

The registry container logs an authentication error when trying to connect to Redis, even though no password is set.

Environment:

• Harbor version: v1.15.1
• Redis version: Bundled with Harbor Helm chart v1.15.1
• Kubernetes version: v1.24.x
• Helm version: v3.x

Additional Context:

While the core and jobservice components are not affected, the registry component consistently logs Redis authentication errors. This suggests that the registry service is attempting to authenticate with Redis, even though authentication is not required due to the absence of a password.

Please provide guidance on whether this is a configuration issue or a bug in the registry service when interacting with Redis.

This is the behavior of the distribution code.
