   bestFor

   Before: ["Users running Docker containers on Linux hosts connected to Tailscale who want simple service exposure without consuming multiple Tailscale device slots.","Users needing automatic service discovery and low manual setup for exposing Docker containers as Tailscale services."]

   After: ["Users running Docker containers on Linux hosts connected to Tailscale who want to expose services without consuming separate Tailscale device slots per container.","Users who want low manual setup and automatic reconciliation of Docker container state changes for Tailscale service exposure."]

   exportFormats

   Before: []

   After: ["Supports HTTP, HTTPS, TCP, and TLS-terminated TCP services through Tailscale."]

   features

   Before: ["Auto Discovery monitors Docker events in real-time and automatically advertises labeled containers as Tailscale services.","Direct IP Proxy routes traffic directly to container IPs on the Docker network without requiring port publishing.","Supports Tailscale Funnel to expose containers to the public internet with a single label."]

   After: ["Auto Discovery monitors Docker events in real-time and automatically exposes labeled containers as Tailscale services.","Direct IP Proxy routes traffic directly to container IPs on the Docker network without requiring port publishing, adapting automatically on container restart.","Funnel Support allows exposing any container to the public internet via Tailscale Funnel with a single label."]

   integrations

   Before: ["Integrates with Docker by monitoring Docker events and reading docktail.* labels on containers."]

   After: ["Integrates with Docker by monitoring Docker events and reading docktail.* labels to expose containers as Tailscale services."]

   limitations

   Before: []

   After: ["Host setup only works on Linux because macOS and Windows do not expose a Unix socket for Tailscale and Docker Desktop runs containers in a VM that cannot mount host Unix sockets.","Rootless Docker requires additional configuration because the DockTail container runs as a non-root user and needs operator permissions to manage Tailscale serve-config writes."]

   summary

   Before: "DockTail automatically exposes Docker containers as Tailscale Services using label-based configuration, enabling zero-config service mesh for dockerized services. It uses native Tailscale Services without creating separate Tailscale device identities per container, and supports HTTP, HTTPS, TCP, and TLS-terminated TCP services."

   After: "DockTail automatically exposes Docker containers as Tailscale Services using label-based configuration, enabling zero-config service mesh for dockerized services. It uses native Tailscale Services without creating separate Tailscale device identities per container, and supports automatic Docker event monitoring and direct IP proxying without port publishing."

   useCases

   Before: ["Expose Dockerized applications securely within a Tailscale network without manual port publishing or complex proxy setup.","Monitor and manage multiple Docker hosts and services with DockTail Cloud for fleet-wide service catalog and health history."]

   After: ["Expose Dockerized applications securely within a Tailscale network without manual port configuration.","Monitor and manage multiple Docker hosts and services from a centralized DockTail Cloud dashboard with health history and alerts."]

   walkthrough

   Before: ["Add docktail.* labels to your Docker containers to enable DockTail to detect and advertise them as Tailscale services.","DockTail detects labeled containers and advertises them to Tailscale automatically.","Access the exposed service via the Tailscale network URL, e.g., http://service."]

   After: ["Add docktail.* labels to your Docker container to enable DockTail to detect and advertise the service to Tailscale.","DockTail detects the labeled container and advertises it to Tailscale automatically.","Access the exposed service via the URL http://service on your Tailnet."]
