What is Docker? Nedir?

Docker was developed by Solomon Hykes at dotCloud in 2013 and revolutionized the software world. By popularizing container technology, Docker enables packaging and running applications with all their dependencies in isolated environments. Docker containers share the operating system kernel, unlike virtual machines, making them much lighter and faster. A Dockerfile codifies the application environment, which is packaged as a Docker image and runs consistently on any Docker-enabled system. The 'it works on my machine' problem is eliminated. Docker Hub hosts millions of ready-made container images. Docker Compose allows multi-container applications (database, web server, cache) to be defined and managed with a single YAML file. Docker is the cornerstone of modern software development and DevOps practices. CI/CD pipelines, microservice architectures, development environment standardization, and cloud deployment are built on Docker. All major cloud providers including Google, Amazon, and Microsoft offer Docker support.
