Can you tell about your experience working with Docker and how you have used it in projects?

In projects, I used Docker for containerizing applications, which allowed creating isolated and reproducible environments for development, testing, and deployment.

Main usage scenarios:

• Creating a Dockerfile to build an application image with the necessary dependencies.
• Running containers with the application and database for local development and integration testing.
• Using Docker Compose to orchestrate multiple services (e.g., application + database + cache).

This helped speed up environment setup, avoid version incompatibility issues, and simplify deployment on servers.

A simple Dockerfile example for a Java application:

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

This approach improved portability and stability of applications across different environments.
