@Jenna, the best place where you can learn about dockerfile is in the official docs Dockerfile reference | Docker Docs
You can read/hear/see another materials, and I truly encourage you to do so, but to have a deeper understanding you need to go to the sources.

Actually, the source image ubuntu does not have timezone set I believe. you have to inject this in your docker file.

Hello, @nithyaks
You have to inject the ENV instruction and assign it DEBIAN_FRONTEND=noninteractive

ENV DEBIAN_FRONTEND=noninteractive
