Other than disk space, Docker-controlled applications do not change your PC. Multiple or legacy versions of the same software can be run at the same time without conflicts, e.g. MySQL 5 and 8. Dependencies can be started, stopped, removed, or reinstalled at any time.
Your project and its dependencies can be distributed to other development machines and production servers. It will work identically, even on different Operating Systems where that software is not natively supported.
Docker ends those “but it works on my PC” complications!
You and other developers can continue to use whatever software you prefer. It does not matter whether you’re using Windows, macOS, Linux, specific IDEs, or other tools. Docker provides all the benefits of local development and debugging.
Docker can scale your application according to demand and keep it running if instances fail.
Despite these benefits, Docker is often shunned by web developers.
Docker is the most useful web development tool you’re not using
It’s considered too technical, unnecessary, or something for DevOps experts. Terminology and resources can be impenetrable and tutorials rarely explain how to use Docker during development.
"Docker for Web Developers" is a book and video course which shows you how to build fast development environments using jargon-free practical examples. The course is aimed at web developers with no previous knowledge of Docker.
You’ll be launching Docker within minutes and can progress at your own pace.
“I knew the sum total of nothing about Docker a month ago. I certainly didn’t appreciate what it could do for the average web developer.” Ben Frain, UK web developer
