The is-docker npm package is a simple utility that allows you to check if your code is running inside a Docker container. This can be particularly useful for altering behavior, debugging, or applying configurations specific to Docker environments.

What are is-docker's main functionalities?

Check if running in Docker

This feature allows you to determine if your application is running inside a Docker container. The `isDocker()` function returns a boolean value: `true` if the environment is detected as a Docker container, and `false` otherwise. This can be useful for adjusting configurations or behavior when running in Docker.

const isDocker = require('is-docker');

if (isDocker()) {
  console.log('Running inside a Docker container!');
} else {
  console.log('Running outside of Docker.');
}
