How does dependency resolution work in Docker?

In Docker, dependency resolution involves determining which packages and libraries are needed for an application to run. This is typically managed through a Dockerfile, where you specify the base image and any additional dependencies.

Can you explain how to specify dependencies in a Dockerfile?

Certainly! You can specify dependencies in a Dockerfile using the RUN command to install packages. For example, you might use RUN apt-get install -y package-name to install a specific package.

What happens if there are conflicting dependencies?

If there are conflicting dependencies, Docker will attempt to resolve them based on the order of commands in the Dockerfile. However, if conflicts cannot be resolved, the build will fail, and you'll need to manually adjust the dependencies.

Are there best practices for managing dependencies in Docker?

Yes, some best practices include keeping your images small, using specific versions of dependencies, and regularly updating your base images to avoid security vulnerabilities.
