🌐 Multi-Instance Traefik Support

Ever wanted to manage services from multiple Traefik proxies in one place? This release adds support for aggregating services from multiple Traefik instances into a single TraLa dashboard. Whether you're running a public-facing proxy alongside a private "*arr" stack, or simply separating concerns across different network zones, TraLa now keeps everything neatly organized in one place. Existing single-instance configurations continue to work without any changes.

What's New

• Multi-Instance Aggregation: TraLa now fetches services from multiple Traefik instances simultaneously and merges them into a unified dashboard view.
• Per-Host View: When more than one instance is configured, services are grouped under collapsible headers per host for clear separation.
• Mix Hosts Toggle: A new toggle combines all services from every instance into a single flat grid while keeping smart grouping available.
• Manual Services Host Field: Manual services now support a host field to pin them to a specific instance in multi-host mode.
• Documentation: New multi-host configuration guide added, covering setup, UI behavior, and migration from single-instance configs.

How to Use

No configuration changes required for single-instance deployments. Just pull the latest image!

docker pull ghcr.io/dannybouwers/trala:v0.17.0
# or
docker pull dannybouwers/trala:v0.17.0

Enable Multiple Instances

Update your configuration.yml to define multiple Traefik instances:

# configuration.yml
version: 4.0

environment:
  traefik:
    instances:
      - api_host: http://traefik-public:8080
        name: Public
      - api_host: http://traefik-arr:8080
        name: Media

The dashboard will automatically detect the mode and adjust the UI accordingly.
