Docker has become a crucial technology for modern software development and DevOps practices. As an open-source platform, it enables developers to package code, runtime, and dependencies into portable containers, making it easier to build, test, and deploy applications across different environments. With Docker's ability to simplify application deployment and management, it's no wonder that it has become increasingly in demand.
