A docker container that starts nginx and redirects all http-queries to given URL.

docker-redirector

A simple NGINX that redirects all traffic to a given URL. It is meant to be run behind a reverse proxy and redirect old/unused (Sub-)Domains.

Config

Configuration is kept extremly simple, all you need to do is adding up to four environmental vars in your docker-command, docker-compose-file or how ever you want to start it.

Var	Meaning	Example
dest	The url all traffic should go to, write only the base domain (https://a.bc.de) if you use keep_uri	dest=https://github.com/cryptkid/docker-redirector"
access_log	The file to write an access-log to. Default: off"	access_log=/var/log/access.log
keep_uri	Keep request uri, redirect from a.example.com/bla to b.example.com/bla and not to b.example.com	keep_uri=true
acme_404	Return 404 to all requests to acme-challenges in order to prevent issues with reverse proxies	acme_404=true

Examples

Docker command

Redirect all queries to this repo:

docker run -e dest='https://github.com/cryptkid/docker-redirector' -e access_log='off' -e keep_uri='false' -it cryptkiddie2/redirector:latest

Redirect to b.example.com keeping the requested uri (a.example.com/bla -> b.example.com/bla)

docker run -e dest='https://b.example.com' -e access_log='off' -e keep_uri='true' -it cryptkiddie2/redirector:latest

docker-compose

There is an an example docker-compose.yml

ToDo and known issues

• Allow multiple redirects for different sources in one container

• https not supported (does not matter in my case because I run it behind traefik
