How to deal with port conflicts in Docker?

The article on avoiding local port conflicts in Docker provides techniques and best practices for effectively managing ports in containers. Docker, a popular application virtualization tool, can sometimes encounter issues related to port conflicts when two or more containers try to use the same port on the host. The author recommends thorough planning and documentation of port mappings to minimize the risk of these conflicts. The article also highlights the use of environment variables and configuration files as ways to flexibly assign ports. Furthermore, tools that can help monitor used ports and which ports are currently free are discussed, making management even easier. Finally, the author emphasizes the importance of testing and validating applications before deployment to ensure everything runs smoothly without port conflicts.
