What is your experience with Docker and how well do you know how to use it in projects?

Docker is a containerization tool for applications that allows packaging an application with all its dependencies into an isolated container.

Experience with Docker typically includes:

• Creating a Dockerfile to describe the application image.
• Building and running containers.
• Using Docker Compose for orchestrating multiple containers (e.g., application + database).
• Optimizing images to reduce size and speed up build times.
• Working with Docker networks and volumes for data storage and container interaction.

In projects, Docker helps ensure a consistent development and production environment, simplifying deployment and scaling.

An example of a simple Dockerfile for a Java application:

FROM openjdk:11-jre-slim
COPY target/myapp.jar /app/myapp.jar
CMD ["java", "-jar", "/app/myapp.jar"]

This container can be run in any environment with Docker without additional configuration.
