Commands
|
|
========
|
|
|
|
* init -N <provider_name>: initialize the container for a new provider named <provider_name>
|
|
This is supposed to be called only once.
|
|
|
|
* start (default command): start the resolver and the dnscrypt server proxy.
|
|
Ports 443/udp and 443/tcp have to be publicly exposed.
|
|
Containers on the same virtual network can directly use this container's Unbound
|
|
instance as a DNS resolver, on the standard DNS port (53).
|
|
|
|
* provider-info: prints the provide name and provider public key.
|
|
|
|
This container has a single volume that you might want to securely keep a
|
|
backup of: /opt/dnscrypt-wrapper/etc/keys
