Technical Annotations (52)

Configuration Parameters (9)
traefik.http.routers.<name>.middlewaresrecommended: app-headers
Must reference existing middleware with correct provider scope
--providers.dockerrecommended: true
Enables Docker provider to watch for container events
certificatesresolvers.<name>.acme.certificatesdurationrecommended: 2160
Certificate validity duration in hours (default 90 days)
certificatesresolvers.<name>.acme.storagerecommended: acme.json
File storing ACME certificates and account data; must be writable
--log.levelrecommended: DEBUG
Required to capture detailed parsing error information in logs
log.levelrecommended: TRACE
Enable detailed logging for configuration troubleshooting
providers.file.filename
Problematic approach that fails to detect changes with Docker volume mounts
providers.file.directory
Working alternative that properly detects file changes in mounted directories
providers.file.watchrecommended: true
Must be enabled for automatic configuration reload, though ineffective with filename approach
