Middlewares

Create / edit

• Choose a type (e.g., headers, forwardAuth, rateLimit, redirectRegex, plugin).
• Provide JSON config; templates appear if templates.yaml is present.
• Saving stores the middleware in the database; it is emitted to Traefik only when assigned to a resource.

Assign to resources

• From a resource detail page, add middlewares and set priority (higher number runs first).
• Bulk assignment is supported via the multi-add flow.

Plugin middlewares

• Use type plugin and set the plugin key matching experimental.plugins.<key> in Traefik static config.
• Ensure the plugin is installed via Plugin Hub and Traefik restarted.

Recommendations

• Keep middleware names descriptive (auth-forward-prod, headers-hsts-strict).
• Use priorities to ensure auth/logging runs before rewrites or header injection.
• Validate via Traefik Explorer → Middlewares to confirm they appear under the file provider.
