Default network ports - Lerian

These are the default internal ports. If you’re using Docker Compose, Kubernetes, or a cloud provider, port mappings may differ. Always verify your configuration before exposing services publicly.

Core services

Service	Port
Midaz Ledger	3002
Midaz Tracer	4020
Lerian Console	8081

Plugin services

Each plugin runs as an independent service and may expose its own API or background processes.

Plugin	Port
Access Manager - Auth	4000
Access Manager - Identity	4001
Reporter Manager	4005

For releases that adopt the health port, charts and examples configure the health listener on 8099. HEALTH_PORT must be set; without it, the health listener does not start. Keep this port internal. Older releases can use other probe ports. See Health and readiness.

For better security, expose only necessary ports (like Console) and restrict others using firewall rules or internal networking policies.

Customization

You can change the default ports using environment variables, Docker Compose files, or Helm values, depending on your setup. If you override a port, make sure to update any references across your infrastructure, load balancers, and API consumers.
