Everybody is using Docker. Pull an image in minutes and start multiple containers in seconds. Great! Unfortunately the public containers are normally not ready for an immediate use as a custom development system: Maybe the debugger is missing, the vhost is not configured correctly, or something app-specific has to be installed first. This presentations shows how to build your own custom system based on a Docker-compose template. This includes also the automatic setup of connections to other systems like DB servers or a load balancer to start a scalable cluster. And the best: The whole system configuration can be simply stored in a version control system, so that the Docker development template is available for all developers on the team.
