-# Docker support
-This is a updated version of the current docker support.
-Container support is only for development purposes and should not be used in production without your own modificatins.
-
-It's not needed to reload the container after you make changes in your current branch.
-
-Images are currently not available in docker hub or other repository, so you have to build them yourself.
-
-After a successful launch PowerDNS-Admin is reachable at http://localhost:9393
-
-PowerDNS runs op port localhost udp/5353
-
-
-## Basic commands:
-### Build images
-cd to this directory
-
-```# ./build-images.sh```
-
-### Run containers
-Build the images before you run this command.
-
-```# docker-compose up```
-
-### Stop containers
-```# docker-compose stop```
-
-### Remove containers
-```# docker-compose rm```
