Your code runs perfectly on your machine, but crashes on the server. Different environments, different dependencies, same headache. This is the problem Docker solves.
Docker packages your application with everything it needs: the code, runtime, libraries, and system settings. This creates a container, a lightweight unit that runs identical everywhere. Think of it as a shipping container for software.
With Docker, you build once and run anywhere. Teams share identical environments, deployments become reliable, and you stop hearing it works on my machine. Try running a pre-built Docker image today and see for yourself.
