Services

Service types

• loadBalancer: HTTP/TCP/UDP backends with optional health checks, sticky sessions, and passHostHeader.
• weighted: distribute across named services with weights.
• mirroring: mirror a percentage of traffic to secondary services.
• failover: primary/fallback pair with health checks.

Create / edit

• Provide JSON config; templates appear if templates_services.yaml exists.
• For TCP/UDP, use address instead of url.

Assign to a resource

• Open a resource → Service override → pick a custom service.
• Removes the default backend for that router; ensure the custom service references valid targets.

Validation tips

• Use health checks where possible.
• For weighted/mirroring, ensure referenced services exist (names must include provider suffix when required, e.g., service-id@file).
• Confirm in Traefik Explorer → Services that the service appears under the file provider and is healthy.
