Traefik cloudflare ssl

Nginx is a great reverse proxy to put in front of your containers. But what if I told you there's another solution? One that involves less configuring, still supports LetsEncrypt, and automatically adapts as you add and remove containers? This post will get you up and running with Traefik and LetsEncrypt with little to no configuration.

What got me interested in Traefik as my reverse proxy was its feature that it can 'watch' for docker containers you are running and automatically start sending requests to them based on the requested host.

Using Traefik as a Reverse Proxy with Docker

In nginx, setting up a proxy to a conatiner is pretty simple. Create a. Nothing crazy, but still a step to be taken. You would have to move or remove the config file for that container until it would start back up. Traefik has many supported backends, and it's docker configuration in my setup looks something like this:.

This is all you need to fire off Traefik and have it automatically start serving traffic to your containers as you add and remove them. No config files, no restarting the process, just simple.

Out of the box when creating a new container instance using docker run Traefik uses two primary methods for routing traffic to containers:. I mentioned above that Traefik just seems to work without config files per container, and this is somewhat right. If your container is named what you want the subdomain to be, the domain in the config will be the domain for every container, and you aren't running your project via docker-composethen you are all set and can skip this section!

But if you're like me and some containers have a name that isn't the subdomain and your entire project is run via docker-composethen read on! If you're running in docker-composethen Traefik will route if the request is formatted like service.

You probably don't want to have the docker compose project in the subdomain.

Also, publishing every container port is usually not necessary since they are all on the same project network and the proxy can route to them without them being exposed. So how do you customize the host and port of each container? Simple add some labels to each container to let Traefik know how you want it to route to it. In this example, this labels block is inside the Plex service definition. This tells Traefik to send requests to this container when the host is plex.

Do not hesitate to complete it. You can provide SANs alternative domains to each main domain.

Take note that Let's Encrypt applies rate limiting. ACME V2 allows wildcard certificate support. As described in Let's Encrypt's post wildcard certificates can only be generated through a DNS challenge. Thus, the wildcard domain has to be defined as a main domain.

Most likely the root domain should receive a certificate too, so it needs to be specified as SAN and 2 DNS challenges are executed. The provider table indicates if they allow generating certificates for a wildcard domain and its root domain. If the HTTP challenge is used, acme. This is a Let's Encrypt limitation as described on the community forum.

It's a Let's Encrypt limitation as described on the community forum. This will request certificates from Let's Encrypt during the first TLS handshake for host names that do not yet have certificates.

TLS handshakes are slow when requesting a host name certificate for the first time. This can lead to DoS attacks! Enable certificate generation on frontend Host rules for frontends wired to the acme.

For example, the rule Host:test1. Refer to wildcard generation for further information. See storeconfig subcommand for further information. Please use a KV Store entry instead. This kind of storage is mandatory in cluster mode. Because KV stores like Consul have limited entry size the certificates list is compressed before it is saved as KV store entry. For example: if acme. Otherwise the backup file will be deleted when the container is stopped. This option is deprecated. Please use dnsChallenge.

Only domains defined here can generate wildcard certificates. Optional but recommended [acme. Note: mandatory for wildcard certificate generation. Optional [acme.
