How is the management and configuration of Docker containers carried out in the current project?

Management and configuration of Docker containers in a project are usually carried out using the following tools and approaches:

• Dockerfile — describes how to build a container image, including the base image, dependency installation, and copying files.

• docker-compose.yml — allows describing multiple services, their connections, ports, volumes, and environment variables for convenient launching of the entire application.

• Docker CLI commands — for starting (docker run), stopping (docker stop), viewing logs (docker logs), and removing containers and images.

• Environment variables and configuration files — for configuring container behavior without changing the image.

• Monitoring and logging — integration with monitoring systems (Prometheus, Grafana) and centralized logging.

An example of a simple docker-compose.yml for a web application:

version: '3'
services:
  web:
    build: .
    ports:
      - "8000:8000"
    volumes:
      - .:/app
    environment:
      - DEBUG=1
  db:
    image: postgres:13
    environment:
      - POSTGRES_USER=user
      - POSTGRES_PASSWORD=pass
      - POSTGRES_DB=appdb
    volumes:
      - pgdata:/var/lib/postgresql/data

volumes:
  pgdata:

Thus, setting up and managing containers is based on describing the infrastructure in configuration files and using standard Docker commands.
