Fors off: I am a total beginner when it comes to docker. I do have some self hosting experience, but run pretty much everything in its on lxc and treat it like a full linux system.

Recently I installed immich in a container and was surprised to see how well it worked.

This lead my to finally tackle something I have been putting off for way to long; installing nightscout (a self hosten glucose monitoring&reporting utility).

For that I followed their guide. Everything worked well up untill the point where I wanted to connect to the web interface. I started of by entering my domain into the nightscout containers arguments (in the form subdomain.domain.tld). Then I used my reverse proxy (nginx, not inside docker) to forward the subdomain to the docker IP on Ports 443, then 80 and lastly the one displayed at the container when listing them with docker ps. None of those worked (I was not able to get a certificate using letsEncrypt and got a 404 when connecting without tls).

I then entered nighscout.[docker-IP] and tried to access it dkrectly which did not work either.

When googling I only find comparisons on how to set up nginx in Docker, or comparisons between the two.

      ### Variables for the container
      NODE_ENV: production
      TZ: [removed]

      ### Overridden variables for Docker Compose setup
      # The `nightscout` service can use HTTP, because we use `traefik` to serve the HTTPS
      # and manage TLS certificates
      INSECURE_USE_HTTP: 'true'

      # For all other settings, please refer to the Environment section of the README
      ### Required variables
      # MONGO_CONNECTION - The connection string for your Mongo database.
      # Something like mongodb://sally:sallypass@ds099999.mongolab.com:99999/nightscout
      # The default connects to the `mongo` included in this docker-compose file.
      # If you change it, you probably also want to comment out the entire `mongo` service block
      # and `depends_on` block above.
      MONGO_CONNECTION: mongodb://mongo:27017/nightscout

      # API_SECRET - A secret passphrase that must be at least 12 characters long.
      API_SECRET: [removed]

      ### Features
      # ENABLE - Used to enable optional features, expects a space delimited list, such as: careportal rawbg iob
      # See https://github.com/nightscout/cgm-remote-monitor#plugins for details
      ENABLE: careportal rawbg iob

      # AUTH_DEFAULT_ROLES (readable) - possible values readable, denied, or any valid role name.
      # When readable, anyone can view Nightscout without a token. Setting it to denied will require
      # a token from every visit, using status-only will enable api-secret based login.
      AUTH_DEFAULT_ROLES: denied

      # For all other settings, please refer to the Environment section of the README

    I Updated the post.

          - 'traefik.http.routers.nightscout.rule=Host(`localhost`)'

    is my current attempt. I used my domain before.

      ‘traefik.http.routers.nightscout.rule=Host(localhost)’

      so traefik will be looking for the host header localhost and only route requests to the service if it matches, sh when you use your real domain that should be what you use as the host header from nginx
