Bifrost is a burning rainbow bridge that reaches between Midgard (Earth) and Asgard, the realm of the gods.

Bifrost

What

Bifrost is a menubar application to providing proxies to various services through SSH.

Why

Sometimes I need a Sock5 proxy to get through BS, and I already have some VPS running around. The other time I have some services running on VPS or a remote machine that I want to tunnel to my machine so that I can use them as-if they were running locally, and I'm too lazy to keep a terminal tab open for each of those service.

How

Bifrost sits on your menubar, and read your ~/.ssh/config for list of servers to connect to.

Given that you already have config like this in your ~/.ssh/config:

Host web
  HostName <remote_ip>
  User <user>
  IdentityFile ~/.ssh/id_rsa

Each time you need a proxy just select the server and enable the service. There's no step 3™. Behind the scene, what the app really does is to create a SSH tunnel to your server, with the correct mapping port-to-port. It is the equivalent of running

ssh -CN -L <port>:127.0.0.1:<port> <remote_ip>

Roadmap

• Kubernetes Pod And Service Discovery
• Automatic startup
• Configuration: allow to define new services and servers, without relying on ~/.ssh/config. We might need this since currently we're not sandbox friendly
• Logging console
• AppStore release
