Working with Containers: Introduction to Docker

If you’re applying for jobs that involve managing and deploying applications, chances are you’ll be expected to know Docker, the platform that helps developers build, share, and run applications. Jobs like Software Developer, DevOps Engineer, Python Developer, Data Engineer, and many more all use Docker regularly.

Since this will be an essential skill for you to succeed in your new role, you’ll want to be prepared for any Docker interview questions that might come your way during the interview process. And one of the best ways you can prepare is to set up a mock interview  — particularly when it comes to the technical interview. You can ask someone to help you by playing the role of the interviewer and asking you a series of questions that are likely to come up in your interview. This helps you practice answering questions out loud, and it’ll also help you identify any questions you need to flesh out before your interview.

Tip: If you’re interviewing remotely, consider setting up your mock interview over Zoom. This way, you can practice in a similar way to how your real interview will be conducted. You can also use Zoom on your own and record yourself answering questions. That way, you can play the recording back and see how you did.

To help you practice, here are 12 Docker interview questions and tips on how to answer them.
