Docker CMD & ENTRYPOINT - Lab 5
This video explains the key differences between CMD and ENTRYPOINT in Dockerfiles and how they affect container behavior.
You will learn how each instruction works, when to use them, and how they interact with runtime commands.
What you’ll learn:
• Purpose of CMD and ENTRYPOINT
• How Docker executes default commands
• Overriding CMD and ENTRYPOINT at runtime
• Using CMD with parameters and exec form
• Combining ENTRYPOINT with CMD effectively
• Practical examples to understand real-world usage
This session is ideal for intermediate learners who want precise control over how containers start and execute applications.
