a simple tool built to redirect http requests in a 5MB docker image
go get github.com/moqmar/redirect
TO=https://example.org PERMANENT=1 PREFIX=/home/ redirect
docker run -d -p 8080:80 -e "TO=https://example.org" -e "PERMANENT=1" -e "PREFIX=/home/" momar/redirect
This will redirect e.g. http://example.com/home/whatever.txt to https://example.com/whatever.txt
| Variable | Description |
|---|---|
TO |
Redirection target/prefix. Required. |
PERMANENT |
Use 301 Moved Permanently instead of 302 Found if this is set to something other than an empty string, 0, false or no. |
PREFIX |
Prefix regular expression to remove from the path - a leading slash is required, a trailing slash is recommended in most cases. To completely ignore the path, set this to .* - the default behaviour is to keep the full path. |
HOST/PORT |
The hostname and port to listen on. |
| Environment | Request | Target |
