Describe your experience with using Docker in projects you have worked on.

In C/C++ projects, I used Docker to create isolated and reproducible development and build environments. This helped avoid dependency issues and different library versions across machines.

Main usage scenarios:

• Creating containers with the necessary compiler and tools (gcc, clang, cmake).
• Automating the build and testing of the project inside the container.
• Simplifying CI/CD setup, where the build occurs in a container with a guaranteed consistent environment.

Example Dockerfile for a C++ project:

FROM ubuntu:20.04
RUN apt-get update && apt-get install -y build-essential cmake
WORKDIR /app
COPY . /app
RUN cmake . && make
CMD ["./my_app"]

This approach helps avoid "it works on my machine" issues and speeds up the integration of new team members into the project.
