I used the acme configuration from the docs: The weird thing was that /etc/traefik/acme/acme.json contained private key, though I don't know how it's supposed to work. This option is useful when internal networks block external DNS queries. I've just moved my website from new.example.com to example.com that was linked to the old version of the website hosted on the different server. When running Traefik in a container this file should be persisted across restarts. In Docker you can mount either the JSON file, or the folder containing it: For concurrency reasons, this file cannot be shared across multiple instances of Traefik. Save the file and exit, and then restart Traefik Proxy. This field has no sense if a provider is not defined. The storage option sets where are stored your ACME certificates. This option allows to set the preferred elliptic curves in a specific order. Here's a report from SSL Checker reporting that secondary certificate, check Certificate #2 the one that says non-SNI: SSL Server Test: sample-custom-dc2.widemeshstaging.net (Powered by Qualys SSL Labs).pdf, For comparison, here's a SSL checker report but using HAPROXY Controller serving the exact same ingresses: it is correctly resolved for any domain like myhost.mydomain.com. One important feature of traefik is the ability to create Lets Encrypt SSL certificates automatically for every domain which is managed by traefik.

It is the only available method to configure the certificates (as well as the options and the stores). I'm still using the letsencrypt staging service since it isn't working. I am a bit puzzled because in my docker-compose I use a specific version of traefik (2.2.1) - so it can't be because of traefik update. Traefik automatically tracks the expiry date of ACME certificates it generates. Note that per the Traefik documentation, you must specify that a service requires the certificate resolver it doesnt automatically get used. The part where people parse the certificate storage and dump certificates, using cron. That flaw has been fixed, and the Let's Encrypt policy states that any mis-issued certificates must be revoked within five days. or don't match any of the configured certificates. 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. It's possible to store up to approximately 100 ACME certificates in Consul. Find centralized, trusted content and collaborate around the technologies you use most. In this use case, we want to use Traefik as a layer-7 load balancer with SSL termination for a set of micro-services used to run a web application. You can configure Traefik to use an ACME provider (like Let's Encrypt) to generate the default certificate. then the certificate resolver uses the main (and optionally sans) option of tls.domains to know the domain names for this router. I think it might be related to this and this issues posted on traefik's github. Conventions and notes; Core: k3s and prerequisites. I've got a LB and some requests without hostnames in my setup that I didn't want to change to fix this issue.

For example, CF_API_EMAIL_FILE=/run/secrets/traefik_cf-api-email could be used to provide a Cloudflare API email address as a Docker secret named traefik_cf-api-email. Edit acme.json to remove all certificates linked to the certificate resolver (or resolvers) identified in the earlier steps. Conversely, for cross-provider references, for example, when referencing the file provider from a docker label, The text was updated successfully, but these errors were encountered: This is HAPROXY Controller serving the exact same ingresses: but Traefik all the time generates new default self-signed certificate. My cluster is a K3D cluster. Code-wise a lot of improvements can be made. if not explicitly overwritten, should apply to all ingresses. If the TLS certificate for domain 'mydomain.com' exists in the store Traefik will pick it up and present for your domain. It is more about customizing new commands, but always focusing on the least amount of sources for truth.

Security events are a fact of Internet life, and when they happen, a swift response is the best way to mitigate risk. With that in place, we can go back to our docker-compose.yml file and add some specific config to request Lets Encrypt security on our whoami service. If no match, the default offered chain will be used. The idea is: if Dokku app runs on http then my Trefik instance should obtain Lets encrypt certificate and make it run on https Certificates that are no longer used may still be renewed, as Traefik does not currently check if the certificate is being used before renewing.
