How can I use a package manager inside a Docker container?

You can use a package manager like apt or yum inside a Docker container by including it in your Dockerfile.

Can you give me an example Dockerfile that uses apt?

Sure! Here's a simple example:

FROM ubuntu:latest

RUN apt-get update && apt-get install -y package-name

What if I want to use a different base image?

You can use any base image that supports your desired package manager. For example, use FROM alpine for apk.

Are there any best practices for using package managers in Docker?

Yes, it's best to minimize the number of layers by combining commands and to clean up cache files after installation.
