Good practices for deploying Docker in production

Docker has revolutionized how applications are deployed, providing a lightweight and flexible solution for managing software environments. In this article, the author outlines the top eight best practices for using Docker in production settings. These practices aim to enhance efficiency, security, and management ease of containers deployed in the real world. One of the key points discussed is minimizing image sizes, which accelerates transfer times and reduces startup durations for containers. Additionally, the article emphasizes the importance of managing data well by using external volumes, which significantly eases updates and migrations. Another vital practice highlighted is the use of immutable images, meaning that images should be kept as unchanged as possible after their creation. This makes tracking changes simpler and allows for easy rollback to previous versions if issues arise. The author also stresses the significance of using monitoring tools to enable real-time tracking of container performance and early detection of potential problems. Lastly, the concept of Continuous Integration and Continuous Delivery (CI/CD) is presented, which greatly improves the workflow in building and deploying applications.
