Point multiple domains to site - Docker

Install / Update Setup
1

Dear erpnext-community,

I recently moved my erpnext from a bench setup to a docker setup.
In the old bench setup, I used multi-tenancy to point different domains to different sites.
I even used multiple domains for one site (e.g. example.com and www.example.com pointed at the same site).

Unfortunately, I am unable to point multiple domains to this one site in docker setup (now just www.example.com points to the site, but not example.com).

During docker installation I used following Environment Variables:

LETSENCRYPT_EMAIL=office@example.com

ERPNEXT_VERSION=v13.16.1

FRAPPE_VERSION=v13.16.0

MARIADB_HOST=mariadb

MYSQL_ROOT_PASSWORD=somesupersecurepassword

SITE_NAME=www.example.com

SITES=`www.example.com`

DB_ROOT_USER=root

ADMIN_PASSWORD=supersecuretoo

INSTALL_APPS=erpnext

ENTRYPOINT_LABEL=traefik.http.routers.erpnext-nginx.entrypoints=websecure

CERT_RESOLVER_LABEL=traefik.http.routers.erpnext-nginx.tls.certresolver=myresolver

HTTPS_REDIRECT_RULE_LABEL=traefik.http.routers.http-catchall.rule=hostregexp(`{host:.+}`)

HTTPS_REDIRECT_ENTRYPOINT_LABEL=traefik.http.routers.http-catchall.entrypoints=web

HTTPS_REDIRECT_MIDDLEWARE_LABEL=traefik.http.routers.http-catchall.middlewares=redirect-to-https

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

SKIP_NGINX_TEMPLATE_GENERATION=0

WORKER_CLASS=gthread

Since I am not really familiar with docker at this point, I would be very grateful for some tips.

To sum it up:
How to point multiple domains (example.com and www.example.com) to my site (www.example.com) in docker setup?

Thank you very much for your time.

Best regards,
AH

check if this helps GitHub - frappe/frappe_docker: Docker images for production and development setups of the Frappe framework and ERPNext

Thank you for your quick response :smiley:
I will try the instructions and will share my experience for others later.

Best regards,

So, I tried it myself now for some time and I am facing issues (due to my lack of skill :neutral_face:).

I edited the file docker-compose.yml in directory frappe-docker as follows:
(Name of docker project is erpnext, name of frappe site is www.example.com)

  erpnext-nginx:
    image: frappe/erpnext-nginx:${ERPNEXT_VERSION}
    restart: on-failure
    environment:
      - FRAPPE_PY=erpnext-python
      - FRAPPE_PY_PORT=8000
      - FRAPPE_SOCKETIO=frappe-socketio
      - SOCKETIO_PORT=9000
      - SKIP_NGINX_TEMPLATE_GENERATION=${SKIP_NGINX_TEMPLATE_GENERATION}
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.erpnext-nginx.rule=Host(${SITES})"
      # edit starts here
      - "traefik.http.routers.custom-domain.rule=Host(`example.com`)"
      - "traefik.http.routers.custom-domain.entrypoints=web"
      - "traefik.http.middlewares.custom-domain.headers.customrequestheaders.Host=www.example.com"
      - "traefik.http.routers.custom-domain.middlewares=custom-domain"
      - "traefik.http.routers.custom-domain.tls.certresolver=myresolver"
      # edit ends here
      - "${ENTRYPOINT_LABEL}"
      - "${CERT_RESOLVER_LABEL}"
      - "traefik.http.services.erpnext-nginx.loadbalancer.server.port=8080"

After I restarted the docker container I expected that entering example.com in a browser would redirect me to www.example.com and the corresponding frappe site.

Unfortunately, that did not happen. I only get “404 page not found”.

Can anyone help me to fix this problem?

Best regards,
AH

Hello everyone, I managed to solve it! :heart_eyes:

I had to comment out the part, where the entrypoints are set (since traefik already had default entrypoint set).

So my docker-compose.yml file looks like this now:

erpnext-nginx:
    image: frappe/erpnext-nginx:${ERPNEXT_VERSION}
    restart: on-failure
    environment:
      - FRAPPE_PY=erpnext-python
      - FRAPPE_PY_PORT=8000
      - FRAPPE_SOCKETIO=frappe-socketio
      - SOCKETIO_PORT=9000
      - SKIP_NGINX_TEMPLATE_GENERATION=${SKIP_NGINX_TEMPLATE_GENERATION}
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.erpnext-nginx.rule=Host(${SITES})"
      # edit starts here
      - "traefik.http.routers.custom-domain.rule=Host(`example.com`)"
      #- "traefik.http.routers.custom-domain.entrypoints=web"
      - "traefik.http.middlewares.custom-domain.headers.customrequestheaders.Host=www.example.com"
      - "traefik.http.routers.custom-domain.middlewares=custom-domain"
      - "traefik.http.routers.custom-domain.tls.certresolver=myresolver"
      # edit ends here
      - "${ENTRYPOINT_LABEL}"
      - "${CERT_RESOLVER_LABEL}"
      - "traefik.http.services.erpnext-nginx.loadbalancer.server.port=8080"

Maybe it can help someone else too :smiley:

Thank you and best regards,
AH
