Traefik Docker SSL Configuration With Lets Encrypt - docker

Question

Hi everyone I am trying to enable SSL in my docker-compose.yml file for my backend service. All of my Traefik configuration is done in my docker-compose.yml file, so I may be missing a line. Running docker-compose on this configuration works without SSL and the site is displayed properly, but it does not work when using https. I have checked the Traefik documentation for the certResolvers and I am not sure what I am missing thanks.

It may not be the only issue, but you are missing a colon in your traefik volumes section. You have:
- /acme.json/etc/traefik/acme.json
I think it should be (assuming your host location is really /acme.json and not ./acme.json or in some other directory):
- /acme.json:/etc/traefik/acme.json
That said, I have also been having an issue where traefik always wants it in /acme.json, so I just put it there instead of in /etc/traefik/acme.json .
