Mostly playing with docker. A simple docker image thing that runs cjdns

cjdns-docker

This is mostly for the purposes of me playing with docker. Use at your own risk.

Usage

For a simple image, just run:

$ docker build -t cjdns https://github.com/thefinn93/docker
$ docker run --privileged cjdns

The --privileged allows it to use special things, specifically the tun device that cjdns needs to do it's magic. By default, it will configure your cjdns instance to auto-peer over the ETHInterface with anyone it can find. On my system, it seems that all the docker containers have the same MAC (same as the host in fact), which makes none of that work. At least not yet. I'll investigate this more later.

Advanced

If you want to add UDP peers, stick them in settings/peers.json. Format is:

{
    "172.17.42.1:59249": {
        "password": "yup",
        "publicKey": "4upjugvc9rmtw08uy61tg17zm66wtxswxsfbr2z30fc9urtdvnm0.k"
    },
    "123.444.55.22:13333" {
        "password": "supa secure password",
        "publicKey": "ThisIsTotallyMyPublicKeyGuies.k"
    }
}

Overriding other cjdns options (for example, setting logging to stdout) can be done with a file called config.json (also in the settings directory). This will replace any values in cjdroute.conf. See settings/config.json.dist for an example. Note that the .dist file is used if no config.json file is found.

Todo:

• functional ETH autopeering
• expose admin interface maybe?
