Each domain & SANs will lead to a certificate request. For complete details, refer to your provider's Additional configuration link. You can also visit the page for yourself, by heading tohttp://whoami.docker.localhost/in your browser. Code-wise a lot of improvements can be made. This default certificate should be defined in a TLS store: If no defaultCertificate is provided, Traefik will use the generated one. This is necessary because within the file an external network is used (Line 5658). 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. Learn more in this 15-minute technical walkthrough. Is there really no better way? is it possible to point default certificate no to the file but to the letsencrypt store?
