DPS is a lightweight end user (Developers, Server Administrators) DNS server toolwhich make it easy to develop in systems where one hostname can solve to different IPs basedon the configured environment, so you can:

• Solve hostnames from local configuration database
• Solve hostnames fromdocker containers
• Solve hostnames from a list of configured remote DNS servers(as a proxy) if no answer of two above
• Solve hostnames using wildcards
• Graphic interface to Create/List/Update/DeleteA/CNAME records
• Solve host machine IP usinghost.docker hostname

Basic running it on Linux or Mac

sudo ./dns-proxy-server --server-port 5555 --register-container-names

$ docker run --rm --name nginx-app nginx$ nslookup -po=5555 nginx-app.docker 127.0.0.1172.17.0.3

Solving docker container from hostname

$ docker run --rm --hostname nginx.dev nginx$ nslookup -po=5555 nginx.dev 127.0.0.1172.17.0.3

Solving from pre-configured entries (conf/config.json):

$ nslookup -po=5555 dps-sample.dev 127.0.0.1192.168.0.254

Solving from Internet

$ nslookup -po=5555 google.com 127.0.0.1142.250.79.174

$ nslookup -po=5555 machine-1.192.168.0.1.stub 127.0.0.1192.168.0.1

Solving host machine IP

$ nslookup -po=5555 host.docker 127.0.0.1172.22.230.67
