+## Apache + Traefik + Sub-Path
+
+This guide was contributes by [incaseoftrouble](https://github.com/incaseoftrouble) in [Issue #266](https://github.com/vabene1111/recipes/issues/266)
+
+My setup is docker-compose / traefik / apache / recipes. Swapping out apache for nginx should be straightforward.
+
+Relevant parts:
+
+docker-compose:
+```yaml
+  apache:
+    # omitting other config
+    volumes:
+      - ./recipes/static:/var/www/recipes/static:ro
+      - ./recipes/media:/var/www/recipes/media:ro
+    labels:
+      traefik.enable: true
+      traefik.http.routers.apache-recipes.rule: Host(`<host>`) && PathPrefix(`/<www path>`)
+      traefik.http.routers.apache-recipes.entrypoints: http
+      traefik.http.routers.apache-recipes.service: apache
+      traefik.http.services.apache.loadbalancer.server.port: 80
+      traefik.http.services.apache.loadbalancer.server.scheme: http
+...
+
+  recipes:
+    volumes:
+      - ./recipes/static:/opt/recipes/staticfiles:rw
+      - ./recipes/media:/opt/recipes/mediafiles:rw
+    environment:
+      # all the other env
+      - SCRIPT_NAME=/<sub path>
+      - STATIC_URL=/<www path>/static/
+      - MEDIA_URL=/<www path>/media/
+    labels:
+      traefik.enable: true
+      traefik.http.routers.recipes.rule: Host(`<host>`) && PathPrefix(`/<sub path>`)
+      traefik.http.routers.recipes.entrypoints: http
+      traefik.http.services.recipes.loadbalancer.server.port: 8080
+      traefik.http.services.recipes.loadbalancer.server.scheme: http
+```
+
+apache: 
+```
+  Alias /<www path>/static/ /var/www/recipes/static/
+  Alias /<www path>/media/ /var/www/recipes/media/
+  <Directory "/var/www/recipes/">
+    Require all granted
+  </Directory>
+```
+
+I used two paths `<sub path>` and `<www path>` for simplicity. In my case I have `<sub path> = recipes` and `<www path> = serve/recipes`. One could also change the matching rules of traefik to have everything under one path.
+
+I left out the TLS config in this example for simplicty.
