Redirector

Rust service for redirecting based on a _redirect TXT record.

Who is this for?

If you just bought a domain but have not set up a webserver yet, you can use 301.systems for redirecting your domain. Some registrars can do this for you, but you can use 301.systems if your registrar does not.

How to use the 301.systems service.

  1. If your dns provider supports CNAME records for a root domain, or you want to set up a subdomain, make a CNAME for 301.systems. Otherwise use an A record that points to 195.201.249.96. You can also create an AAAA record with this ipv6 address: 2a01:4f8:1c1c:31c8::1.

  2. Set up a TXT record for _redirect.yourdomain.tld. The TXT record should contain a valid URL to the site that you want to be redirected to. For example:

$ dig TXT _redirect.301.systems

; <<>> DiG 9.9.7-P3 <<>> TXT _redirect.301.systems
;; global options: +cmd
;; Got answer:

;; WHEN: Wed Apr 11 16:24:26 CEST 2018
;; MSG SIZE  rcvd: 100

You should now be redirected when you visit yourdomain.tld.

Running

If you want to host the rust service yourself you can take these steps:

  1. Clone this repository (git clone https://github.com/pingiun/Redirector)
  2. Build the project with cargo build --release or with docker: docker build -t redirector .
  3. When running the program, supply the LISTEN_ADDR environment variable, for example:
LISTEN_ADDR=localhost:8080 RUST_LOG=redirector=info target/release/redirector

or in docker (example uses the docker hub version):

docker run -e LISTEN_ADDR=0.0.0.0:80 -p 80:80 -d pingiun/redirector

If you want to run on ipv6 as well (or any other address), you can supply the LISTEN_ADDR_6 environment variable.

Deploying on kubernetes

This project has supplied a kubernetes deployment to run redirector with 3 replicas. You can change the deploy.yaml file to your needs and create the deployment with kubectl create -f deploy.yaml.

You can’t perform that action at this time.
