DNSCrypt server Docker image
|
|
============================
|
|
|
|
Run your own caching, non-censoring, non-logging, DNSSEC-capable,
|
|
[DNSCrypt](http://dnscrypt.org)-enabled DNS resolver virtually anywhere!
|
|
|
|
If you are already familiar with Docker, it shouldn't take more than 5 minutes
|
|
to get your resolver up and running.
|
|
|
|
Installation
|
|
============
|
|
|
|
Think about a name. This is going to be part of your DNSCrypt provider name.
|
|
If you are planning to make your resolver publicly accessible, this name will
|
|
be public.
|
|
It has to look like a domain name (`example.com`), but it doesn't have to be
|
|
a registered domain.
|
|
|
|
Let's pick `example.com` here.
|
|
|
|
Download, create and initialize the container, once and for all:
|
|
|
|
$ docker run --name=dnscrypt-server -p 443:443/udp -p 443:443/tcp --net=host \
|
|
jedisct1/unbound-dnscrypt-server init -N example.com
|
|
|
|
This will only accept connections via DNSCrypt on the standard port (443).
|
|
|
|
`--net=host` provides the best network performance, but may have to be
|
|
removed on some shared containers hosting services.
|
|
|
|
Now, to start the whole stack:
|
|
|
|
$ docker start dnscrypt-server
|
|
|
|
Done.
|
|
|
|
To check that your DNSCrypt-enabled DNS resolver is accessible, run the
|
|
DNSCrypt client proxy on another host:
|
|
|
|
# dnscrypt-proxy \
|
|
--provider-key=<provider key, as displayed when the container was initialized> \
|
|
--resolver-address=<dnscrypt resolver public IP address> \
|
|
--provider-name=2.dnscrypt-cert.example.com
|
|
|
|
And try using `127.0.0.1` as a DNS resolver.
|
|
|
|
Note that the actual provider name for DNSCrypt is `2.dnscrypt-cert.example.com`,
|
|
not just `example.com` as initially entered. The full name has to start with
|
|
`2.dnscrypt-cert.` for the client and the server to use the same version of the
|
|
protocol.
|
|
|
|
Let the world know about your server
|
|
====================================
|
|
|
|
Is your brand new DNS resolver publicly accessible?
|
|
|
|
Fork the [dnscrypt-proxy repository](https://github.com/jedisct1/dnscrypt-proxy),
|
|
edit the [dnscrypt.csv](https://github.com/jedisct1/dnscrypt-proxy/blob/master/dnscrypt-resolvers.csv)
|
|
file to add your resolver's informations, and submit a pull request to have it
|
|
included in the list of public DNSCrypt resolvers!
