DockTail is a Go-based Docker sidecar that watches container events, reads docktail.* labels, and exposes matching containers as native Tailscale Services. It proxies directly to container IPs so apps need no published ports, supports HTTP/HTTPS/TCP, automatic certificates, Funnel, and automatic reconciliation.

Use cases

• expose docker containers to my tailnet without publishing ports
• give each homelab app a tailscale hostname automatically
• avoid burning tailscale device slots per self-hosted app
• share a container publicly via tailscale funnel
• auto-reconcile tailscale services when containers restart
• add tcp services behind tailscale with proxy protocol
• monitor docker services across multiple hosts

When to choose

• you run docker with tailscale and want label-driven service exposure
• you want native tailscale services instead of per-app proxy devices
• you prefer zero published ports and direct container-IP proxying
• you want automatic reconciliation and funnel support with minimal setup

When to avoid

• you don't use tailscale or docker
• you need a general-purpose reverse proxy beyond tailnet exposure
• you require kubernetes rather than docker/compose environments
• you need per-container tailscale device identities
