Docker explained for non-technical founders

Containers help your developers deliver the same app everywhere, from a laptop to the live server. Here is what that means for you.

You may have heard your developers mention Docker. You do not need to use it, but it helps to understand what it does for your project.

The problem it solves

"It works on my machine" is one of the oldest complaints in software. Different computers have different versions of PHP, Node.js, databases and settings, so an app can behave differently in each place.

What a container is

A container packages an application together with everything it needs to run. Think of a shipping container: whatever is inside, it can be loaded onto any ship or truck in the same way.

Why it matters to the business

  • Faster onboarding: a new developer can run the whole project with a single command.
  • Fewer surprises: test and live environments behave the same.
  • Easier scaling: more copies of a container can be started when traffic grows.
  • Safer updates: a bad release can be rolled back quickly.

Is it always needed?

Not for a simple brochure website. It becomes valuable for web applications, APIs, microservices and teams with more than one or two developers.

The bottom line

Docker is a behind-the-scenes tool that saves time and reduces risk. Ask your development partner whether it is used on your project; ours is, on every serious build.
