The recent major release v3 of Traefik, brought new features or concretized some. Such as certificates via Tailscale and HTTP3.

How to use Tailscale certificates with Traefik

The new release of Traefik with major release 3, introduced some new features. Among them is the integration with Tailscale certificates. This new feature makes it easy to have certificates for https. Of course, there are some limitations and they must be considered (installation on docker): Tailscale must be running on the machine on which docker is running currently (see #9772) may only apply for the certificate of the local machine (hostname defined on Tailscale admin panel) Tailscale configuration Several guides can be found on how to create Tailscale networks, so it will not be part of this guide.

Wake-on-LAN from Guacamole in docker

The Guacamole service allows a “Wake on LAN” (WOL) packet to be launched before connecting to the machine with VNC or RDP. Unfortunately, by Docker’s default setting, networks configured as bridge do not allow broadcast packets (even if directed to a specific subnet) to be sent out. This prevents the use of WOL and Guacamole. There remains the option of configuring the guacd container on the host network, but this solution has security issues. Continue reading

Concept Cloudflare creates a dedicated certificate that allows the server to communicate only with Cloudflare’s servers. Continue reading
