Zero Zone

This project is still in preparation. I'm moving this from 0zone.mkm.pub to a non-personal domain

Zero Zone is a Zero Conf public domain registrar.

With Zero Zone, anybody can create a zone. Zero Zone is automation friendly; no registrations, no captchas. A zone is just a JSON file available via IPFS.

$ dig A foo.bafybeihebkzwbf2en26r7gtpvmbowai7fgvkcvhwaczgehvgzmghfyzvcq.0zone.mkm.pub +short
10.20.30.40

Zero zones are not good-looking. If you want a better looking name, or one you can choose yourself this tool is not for you. Whether zero zones are temporary is up to you: as long as the IPFS file gets served the zone is alive.

The zone is then mapped as subdomain of 0zone.mkm.pub, using the base32 encoding of the IPFS file address.

The JSON zone format reuses Google's Cloud DNS format, for no other reason except that the authors didn't yet find a better standard (suggestions accepted) and this was easy to parse.

         ],
         "type" : "A",
         "ttl" : 600,
         "name" : "foo"
      },
      {
         "type" : "TXT",
         "rrdatas" : [
            "yadda yadda"
         ],
         "name" : "_acme-challenge.foo",
         "ttl" : 600
      }
   ]
}

Background

When automating deployments that require TLS certificates, you often also need to automate DNS, which in turn requires the automation to have API access to a DNS service. This raises the barrier to entry for those who just want deploy something anywhere, without having to have access to a cloud DNS service.

An example use case for this tool is streamlining installation procedures for Bitnami Kubernetes Production Runtime

Install

These instructions assume a IPFS node running on localhost.

1. clone this outside of the GOPATH (so go modules work)
2. cd cmd/server
3. go build && ./server

You can try it out in another shell:

$ dig  @127.0.0.1 -p 8053 A foo.bafybeihebkzwbf2en26r7gtpvmbowai7fgvkcvhwaczgehvgzmghfyzvcq.0zone.mkm.pub +short
10.20.30.40
$ dig  @127.0.0.1 -p 8053 A foo.bafybeihumd6kyjmghotygjnrgzsyiukyjyrgzticnnf5z7eoeep563eiti.0zone.mkm.pub +short
4.3.2.1

PRs accepted.

Main TODOs:

1. build docker image and deploy somewhere public (I'm preparing 0zone.mkm.pub for now)
