I try to setup Traefik to get certificates from Let's Encrypt using DNS challenge and secure a whoami app with this certificate. These instructions assume that you are using the default certificate store named acme.json. If Let's Encrypt is not reachable, the following certificates will apply: For new (sub)domains which need Let's Encrypt authentication, the default Traefik certificate will be used until Traefik is restarted. At Qloaked we call this the application endpoint (and its not a local Docker server), but for this instance well use the basic whoami Docker service provided for us by Containous.

This will request a certificate from Let's Encrypt during the first TLS handshake for a host name that does not yet have a certificate.

When using a certificate resolver that issues certificates with custom durations, one can configure the certificates' duration with the certificatesDuration option. It is managing multiple certificates using the letsencrypt resolver. If the valid configuration with certResover exists Traefik will try to issue certificates from LetsEncrypt.

Traefik is a popular reverse proxy and load balancer often used to manage incoming traffic to applications running in Docker containers and Kubernetes environments. Finally, we're giving this container a static name called traefik. storage replaces storageFile which is deprecated. To configure where certificates are stored, please take a look at the storage configuration. 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. The default certificate can point only to the mentioned TLS Store, and not to the certificate stored in acme.json. in order of preference. is it possible to point default certificate no to the file but to the letsencrypt store? traefik.ingress.kubernetes.io/router.tls.options:
