We have complex systems, interacting with each other. What about testing and continuous integration / continuous delivery?
How do we keep up to date with new technologies?
When we started working for the first time with Docker and Docker containers, we tried to keep it simple and use the base images that are offered on Docker-Hub for free. These containers are really useful for testing environments, but it is risky to base your productive environment on them because, in the end, you do not really know what these images contain.
