This is a tiny Go program for redirecting web requests from one hostname to another. Originally intended for redirecting to/from www subdomains, but configurable to redirect to any host.

Usage

./apexredirector [-config <path>]

By default, apexredirector will look in the current directory for a config.yml; otherwise, you can provide a custom file path with -config.

Docker

An official Docker container image is published GitHub Packages.

$ docker run -p 8080:8080 -v my_config.yml:/config.yml ghcr.io/blackieops/apexredirector

Configuration

apexredirector isn't very useful unconfigured, as without any redirects it will just return an error for every request.

Here's an example configuration file:

---
# If true, will always redirect to `https`; if false, will use the same
# protocol as the request. Defaults to `true`.
secure: true

# A list of objects which represent each redirect that will be served. Any host
# not listed as a "from" in this list will return an HTTP 404 response.
redirects:
  - from_host: "example.com"
    to_host: "www.example.com"

  - from_host: "contoso.com"
    to_host: "microsoft.com"

To control which port apexredirector listens on, you can set the PORT environment variable.

Development

This is a very standard Go application.

To run the program locally:

$ go run .

To run the test suite:

$ go test
