Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 255

A developer has built a Docker image named 'devcor12a3b456789' using the Dockerfile named ‘devcor98b7a654321' and now needs to containerize it. Which command must the developer use?

Answer options

• A. docker run --name devcor12a3b456789 -i -t devcorapp
• B. docker run --name devcorapp -i -t devcor12a3b456789
• C. docker build --name devcor12a3b456789 -i devcorapp
• D. docker build --name devcorapp -i devcor12a3b456789

Correct answer: B

Explanation

The correct command is B because it runs the container named 'devcorapp' from the image 'devcor12a3b456789'. Option A incorrectly attempts to name the container with the image name, while options C and D are incorrect as they use the 'docker build' command, which is not used for running containers.
