Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
-p 80:8080
Port mapping is done using -p host_port:container_port. So -p 80:8080 maps host port 80 to container port 8080.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
-p 80:8080
Why this is correct
Correct. Maps host port 80 to container port 8080.
- ✗
-P
Why it's wrong here
-P publishes all exposed ports to random high ports on the host, not a specific mapping.
- ✗
-p 8080:80
Why it's wrong here
This maps host port 8080 to container port 80, which is opposite.
- ✗
--expose 8080
Why it's wrong here
--expose only informs Docker that the container listens on the specified port, but does not publish it.
