Docker Web-Redirect

This Docker container exposes port 80 and redirects all web traffic to the given target domain/URL.

Features

• Lightweight: Uses only ~2 MB RAM on Linux
• Keeps the URL path and GET parameters
• Permanent redirect (HTTP 301) or Temporary redirect (HTTP 302) or Transparent redirect (proxy pass)

Usage

Docker run

The target domain/URL is set by the REDIRECT_TARGET environment variable.

The redirect type is set by the REDIRECT_STATUS environment variable (defaults to 301, may be set to 301 or 302 or transparent only).

You could enable stub_status page by setting ENABLE_STATUS_PAGE to 1.

Possible redirect targets include domains (<NEW_DOMAIN.COM>), paths (<NEW_DOMAIN.COM>/my_page) or specific protocols (https://<NEW_DOMAIN.COM>/my_page).

Example: $ docker run --rm -d -e REDIRECT_TARGET=<NEW_DOMAIN.COM> -p 80:80 rkcreation/web-redirect

Paths are retained

The URL path and GET parameters are retained. That means that a request to http://<OLD_DOMAIN.COM>/index.php?page=2 will be redirected to http://<NEW_DOMAIN.COM>/index.php?page=2 when REDIRECT_TARGET=<NEW_DOMAIN.COM> is set.

Redirect types

Redirects could be :

• REDIRECT_STATUS=301 (or not set) : permanent redirect (HTTP status code 301). That means browsers will cache the redirect and will go directly to the new site on further requests. Also search engines will recognize the new domain and change their URLs.
• REDIRECT_STATUS=302 : temporary redirect (HTTP status code 302).
• REDIRECT_STATUS=transparent : transparent redirect (with nginx proxy_pass directive).

Docker Compose

With Jwilder Proxy

This image can be combined with the jwilder nginx-proxy. A sample docker-compose file that redirects <OLD_DOMAIN.COM> to <NEW_DOMAIN.COM> could look like this:

version: '3'
services:
  redirect:
    image: rkcreation/web-redirect:latest
    restart: always
    environment:
      - VIRTUAL_HOST=<OLD_DOMAIN.COM>
      - REDIRECT_TARGET=<NEW_DOMAIN.COM>
      - REDIRECT_STATUS=301

With Traefik

This image can be combined with traefik proxy. A sample docker-compose file that redirects <OLD_DOMAIN.COM> to <NEW_DOMAIN.COM> could look like this:

version: '3'
services:
  redirect:
    image: rkcreation/web-redirect:latest
    restart: always
    environment:
      - REDIRECT_TARGET=<NEW_DOMAIN.COM>
      - REDIRECT_STATUS=301
    labels:
      - "traefik.frontend.rule=Host:<OLD_DOMAIN.COM>;"
