I’m currently working on deploying n8n and our security team has specific requirements around Redis connectivity. We need to enable TLS for Redis connections and configure CA certificates to ensure secure communication.
I’ve checked the official n8n documentation at https://docs.n8n.io/hosting/configuration/environment-variables/queue-mode/, but I couldn’t find detailed information about configuring TLS CA certificates for Redis connections.
So I have the following questions:
1. Does n8n currently support configuring TLS CA certificates for Redis connections in queue mode?
2. If yes, what are the specific environment variables or configuration options we should use?
3. If this isn’t currently supported, is it on the roadmap for a future release?
4. Additionally, does n8n’s Redis client support loading CA certificates from the system trust store (e.g., certificates added via `update-ca-certificates` in `/usr/local/share/ca-certificates/` on Debian/Ubuntu systems)? Or does it require explicit CA certificate configuration through environment variables?
For reference, our specific requirements include:
- Redis connection over TLS
- Custom CA certificate configuration
- Running n8n in queue mode with multiple workers
