Correct answer & explanation
✓

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
docker run -d --rm -p 8080:80 image
Why this is correct
Correct flags for detached mode, auto-remove, and port mapping.
- ✗
docker run -it --rm -p 80:8080 image
Why it's wrong here
Port mapping is reversed (host:container) and -it is interactive, not detached.
- ✗
docker create --rm -p 8080:80 image
Why it's wrong here
docker create only creates a container; it does not run it.
- ✗
docker start -d -p 8080:80 image
Why it's wrong here
docker start is for existing containers, not for running a new container from an image.
