Commands
|
|
========
|
|
|
|
* init -N <provider_name> -E <external ip>:<port>
|
|
initialize the container for a server accessible at ip <external ip> on port
|
|
<port>, for a provider named <provider_name>. This is required only once.
|
|
|
|
* start (default command): start the resolver and the dnscrypt server proxy.
|
|
Ports 443/udp and 443/tcp have to be publicly exposed.
|
|
|
|
* provider-info: prints the provider name and provider public key.
|
|
|
|
* shell: run a shell
|
|
|
|
This container has a single volume that you might want to securely keep a
|
|
backup of: /opt/encrypted-dns/etc/keys
