When both container labels and segment labels are defined, container labels are just used as default values for missing segment labels but no frontend/backend are going to be defined only with these labels. Hi @bithavoc , could you provide a reproduction case (let's say with a script using curl and/or openssl that underlines this behavior, without any caching risk from web browser) ? The defaultGeneratedCert definition takes precedence over the ACME default certificate configuration. It will attempt to connect via the domain name AND the IP address, which is why you get the non-match due to the IP address connections. CurveP521) and the RFC defined names (e. g. secp521r1) can be used. I've been trying to get LetsEncrypt working with Traefik, but unfortunately I continue to get the Traefik Default Cert instead of a cert provided by LetsEncrypt's staging server.

You can configure Traefik to use an ACME provider (like Let's Encrypt) for automatic certificate generation. I think there's a chance Traefik might be returning the certificates in the wrong order randomly, so in some requests it sometimes returns the matching SNI certificate first and then the default while some other times it returns the default certificate first and then the matching certificate SNI second. Traefik can use a default certificate for connections without a SNI, or without a matching domain. TLDR: traefik does not monitoring the certificate files, it monitors the dynamic config file Steps: Update your cert file; Touch dynamic.yml; Et voil, traefik has reloaded the cert file; There might be a gotcha with the default certificate store.

Prerequisites; Cluster creation; Cluster destruction . See also Let's Encrypt examples and Docker & Let's Encrypt user guide. Enable the Docker provider and listen for container events on the Docker unix socket we've mounted earlier. Docker containers can only communicate with each other over TCP when they share at least one network. If you do find this key, continue to the next step. One important feature of traefik is the ability to create Lets Encrypt SSL certificates automatically for every domain which is managed by traefik. When multiple domain names are inferred from a given router, Also, I used docker and restarted container for couple of times without no lack. When using KV Storage, each resolver is configured to store all its certificates in a single entry. I deploy Traefik v2 from the official Helm Chart : helm install traefik traefik/traefik -f traefik-values.yaml. CNAME are supported (and sometimes even encouraged), Please check the configuration examples below for more details. Segment labels allow managing many routes for the same container. You can delay this operation by specifying a delay (in seconds) with delayBeforeCheck (value must be greater than zero). Traefik Proxy and Traefik Enterprise users with certificates that meet these criteria must force-renew the certificates before that time. For some reason traefik is not generating a letsencrypt certificate. A lot was discussed here, what do you mean exactly? You can use the teectl command to obtain a list of all certificates and then force Traefik Enterprise to obtain new ones. A certificate resolver is responsible for retrieving certificates. I've got a LB and some requests without hostnames in my setup that I didn't want to change to fix this issue.

Let's encrypt, Kubernetes and Traefik on GKE, Problem getting certificate from let's encrypt using Traefik with docker. Thanks a lot! I ran into this in my traefik setup as well. if the certResolver is configured, the certificate should be automatically generated for your domain. This default certificate should be defined in a TLS store: File (YAML) # Dynamic configuration tls: stores: default: defaultCertificate: certFile: path/to/cert.crt keyFile: path/to/cert.key File (TOML) Kubernetes This makes sense from a topological point of view in the context of networking, since Docker under the hood creates IPTable rules so containers can't reach other containers unless you'd want to. If the TLS certificate for domain 'mydomain.com' exists in the store Traefik will pick it up and present for your domain. Note that Let's Encrypt API has rate limiting. Please note that multiple Host() matchers can be used) for specifying multiple domain names for this router. I tested several configurations and created my own traefik instances on my local machine until I came up with this docker-compose.yml: This file contains several important sections: Before running the docker-compose.yml a network has to be created! We can install it with helm. By continuing to browse the site you are agreeing to our use of cookies. Also, only the containers that we want traffic to get routed to are attached to the web network we created at the start of this document.

If you are required to pass this sort of SSL test, you may need to either: Configure a default certificate to serve when no match can be found: TLS handshakes will be slow when requesting a host name certificate for the first time, this can lead to DoS attacks. It is managing multiple certificates using the letsencrypt resolver. Traefik configuration using Helm Use Let's Encrypt staging server with the caServer configuration option (commit). Its getting the letsencrypt certificate fine and serving it but traefik keeps serving the default cert for requests not specifying a hostname. I have to close this one because of its lack of activity . As described on the Let's Encrypt community forum, Any ideas what could it be and how to fix that? I would expect traefik to simply fail hard if the hostname is not known when using SNI not serve a default cert. There are two ways to store ACME certificates in a file from Docker: This file cannot be shared per many instances of Trfik at the same time. However, frequently, I will refer you back to my previous guides for some reading to not make this guide too lengthy. Let's Encrypt has been applying for certificates for free for a long time. If so, how close was it? If you have any questions, please reach out to Traefik Labs Support or make a post in the Community Forum. Let's Encrypt has done precisely that, and while revoking certificates with short notice has sent everyone scrambling, it also assures that no invalid or misissued certificates will be protecting anyone's Internet properties. If it is, in fact, related to the "chicken-and-egg problem as the domain shouldn't be moved to the new server before the keys work, and keys can't be requested before the domain works", I would recommend to use user-defined certificates for 24 hours after dns updates. You can read more about this retrieval mechanism in the following section: ACME Domain Definition. All-in-one ingress controller, API gateway, and service mesh, How to Reduce Infrastructure Costs by Consolidating Networking Tools, Unlock the Potential of Data APIs with Strong Authentication and Traefik Enterprise. Also, we're making sure the container is automatically restarted by the Docker engine in case of problems (or: if the server is rebooted). If acme.json is not saved on a persistent volume (Docker volume, Kubernetes PersistentVolume, etc), then when Traefik Proxy starts, no acme.json file is present. The last step is exporting the needed variables and running the docker-compose.yml: The commands above will now create two new subdomains (https://dashboard.yourdomain.de and https://whoami.yourdomain.de) which also uses an SSL certificate provided by Lets Encrypt, I hope this article gave you a quick and neat overview of how to set up traefik. but there are a few cases where they can be problematic. In every start, Traefik is creating self signed "default" certificate. Defining an info email (, Within the volumes section, the docker-socket will be mounted into, Global redirect to HTTPS is defined and activation of the middleware (. if not explicitly overwritten, should apply to all ingresses.
