Application deployment is becoming more and more complex. Getting a dedicated server, installing, setting up and maintaining applications is just the beginning. The risk of system failure always exists in the face of complex and tightly coupled systems, different services and programming languages.
Docker makes software delivery easy again. It allows you to set up Everything — the software you develop, the operating system it runs, the services it needs, modules, and backend tools (such as cron jobs). All of this can be set up in minutes and ensures that it works as well on the target system as your development environment. Our Docker quick lookup table brings together the commands you most likely need in your Docker workflow so that you can focus on your work rather than searching Google’s deepest, darkest corners. Enjoy it!
