Docker Certified Associate Certification Training Course - Demo - Show Difference Between Entry Point and CMD

This video tutorial explains the difference between the entry point and CMD commands in Docker. It begins with an introduction to these concepts, followed by creating a Docker file that includes both an entry point and a CMD. The tutorial then demonstrates building a Docker image from this file and running it as a container. The video highlights how the entry point and CMD behave differently when additional arguments are passed, emphasizing that the entry point remains unchanged while CMD can be overridden. The tutorial concludes by summarizing the key differences between these two Docker commands.
