Getting Started with Docker: How to Containerize Your First Application

Docker solves the "works on my machine" problem by containerizing applications for consistent execution across environments. The tutorial guides users through installing Docker, creating a simple Python Flask application, and building a Dockerfile to define the container image. Building and running the container involves using Docker commands to create and start the image. Sharing the container is achieved by pushing the image to Docker Hub. Managing containers includes commands for listing, stopping, and removing containers. Docker Compose simplifies managing multi-container applications. Cleaning up unused Docker resources is crucial to manage disk space. Running containers in detached mode allows background operation and log checking. Finally, deploying containers to cloud platforms like AWS, Google Cloud, and Azure is discussed.
