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. Finally but not unimportantly, we tell Traefik to route to port 9000, since that is the actual TCP/IP port the container actually listens on. If you do find a router that uses the resolver, continue to the next step. During Trfik configuration migration from a configuration file to a KV store (thanks to storeconfig subcommand as described here), if ACME certificates have to be migrated too, use both storageFile and storage. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Docker for now, but probably Swarm later on.

The TLS options allow one to configure some parameters of the TLS connection. They will all be reissued. This is the general flow of how it works. distributed Let's Encrypt, 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. or don't match any of the configured certificates. How can i use one of my letsencrypt certificates as this default? distributed Let's Encrypt, you must specify the provider namespace, for example: like: I'm sorry, but I have a feeling that you can't say "no, we don't have such functionality" and because of that, you are answering any question which not I'm asking.
