* 'master' of github.com:DNSCrypt/dnscrypt-server-docker:
Fix incorrect port in README for Docker Compose (#107)
Updated Kubernetes configurations and added docker-compose support (#106)
Removed --net=host as default for the docker container
It does forward port 443 tcp/udp to the host, but it also had "--net=host" when starting. That defeats the purpose of the port forward.
Removing "--net=host" as it is also in line with the rest of the documentation.
1) I have deleted the "mkdir -p /etc/dnscrypt-server/keys" section in Installation: in fact with "-v /etc/dnscrypt-server/keys:/opt/encrypted-dns/etc/keys" the directory is automatically created on the host.
2) I have eliminated the options -"-ulimit nofile=90000:90000" and "--net=host" from the docker run command in Installation, because the first one was used in old versions of Docker, because they did not tolerate the limit of the number of files open simultaneously, managed by the kernel , in the standard Ubuntu session settings (and others); the second (--net=host) actually exposes the entire host stack to the container and this does not speed up, but exposes to risk and cancels the much more useful option -p 443:443/udp -p 443:443/tcp (see https://docs.docker.com/network/host/).
3) I have deleted in Installation the explanation regarding the "--net=host" option as explained in point 2.
4) In Installation, I have eliminated the section of the "docker start command dnscrypt-server", because, when the container with docker run is deployed, it is also started.
