docker-compose explanation

docker-compose.yml conatins a whoami test instance with http-to-https redirect features

    labels:
      - "traefik.enable=true"
      # default route
      - "traefik.http.routers.whoami.rule=Host(`whoami.domain.tld`)"
      - "traefik.http.routers.whoami.entrypoints=https"
      - "traefik.http.routers.whoami.tls.certresolver=${PROVIDER}"
      # HTTP to HTTPS
      - "traefik.http.middlewares.redirect-to-https.redirectscheme.scheme=https"
      - "traefik.http.routers.whoami-redirs.rule=hostregexp(`{host:.+}`)"
      - "traefik.http.routers.whoami-redirs.entrypoints=http"
      - "traefik.http.routers.whoami-redirs.middlewares=redirect-to-https"

sections explanation:

• enable traefik configuration on this container

      - "traefik.enable=true"

• configure router to serve "whoami.domain.tld" FQDN over https entrypoint and generate SSL certificate using provider defined inside .env (eg: route53 )

      - "traefik.http.routers.whoami.rule=Host(`whoami.domain.tld`)"
      - "traefik.http.routers.whoami.entrypoints=https"
      - "traefik.http.routers.whoami.tls.certresolver=${PROVIDER}"

• configure http-to-https redirect scheme

      - "traefik.http.middlewares.redirect-to-https.redirectscheme.scheme=https"

• apply redirect scheme to every request directed to host over http (link)

      - "traefik.http.routers.whoami-redirs.rule=hostregexp(`{host:.+}`)"
      - "traefik.http.routers.whoami-redirs.entrypoints=http"
      - "traefik.http.routers.whoami-redirs.middlewares=redirect-to-https"
