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	Name
Midaz Onboarding	3000	midaz_onboarding
Midaz Transaction	3001	midaz_transaction
Midaz Ledger	3002	midaz_ledger
Transaction gRPC	3011	midaz_transaction_grpc
Midaz Console	8081	midaz-console
Matcher	8080	matcher

Plugin services

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

Plugin	Port	Name
Access Manager - Auth	4000	plugin-auth
Access Manager - Identity	4001	plugin-identity
Fees Engine	4002	plugin-fees
CRM	4003	plugin-crm
Reporter Manager	4005	reporter-manager

For better security, expose only necessary ports (like Console and MCP) 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.
