Traefik 2.0: Wildcard Let's Encrypt Certificates

Tue, 12 Nov 2019 00:00:00 +0000

Introduction

In this tutorial we will setup Traefik to obtain wildcard certificates from Let’s Encrypt. This requires DNS challenge to be setup. Usually Traefik obtains a certificate for every subdomain. We can simplify this process by telling Traefik to use a wildcard (*.example.com) certificate instead.

Prerequisites

Registered Domain
Authoritative DNS Servers from one of these providers (you may need to change your DNS servers of your domain to one of the provider in the list)

In this tutorial we will use Cloudflare as our DNS servers for our domain.
