Docker is an open-source platform designed to automate the deployment, scaling, and management of applications using containerization. A container is a lightweight, standalone, and executable package that includes everything needed to run an application, such as the code, libraries, environment variables, and dependencies.
Think of containers as isolated environments that allow developers to ensure their application will run the same regardless of where it is deployed. Containers are much lighter than virtual machines (VMs) because they share the same operating system kernel but isolate the application’s processes.
Sounds good? Let’s get Docker installed then!
