Docker Volume: Data Persistence and Volume Management in container

Course Description

This course offers a comprehensive guide to mastering data persistence and management within the Docker ecosystem. You will move beyond stateless containers and learn how to handle application data effectively using all major Docker volume types. Through a series of practical, hands-on labs, you will explore anonymous volumes, bind mounts, and named volumes, understanding the ideal use case for each. The curriculum progresses from single-container setups to managing complex, multi-container applications using Dockerfile instructions and Docker Compose. By the end of this course, you'll be able to confidently architect stateful applications, ensure data survives container restarts, and efficiently share data between services.

Who is this course for

This is an intermediate-level course designed for individuals who are already familiar with the basics of Docker and want to deepen their knowledge of data management. It's perfect for:

• Software Developers: Who need to manage databases, user uploads, or configuration files for their containerized applications.

• DevOps Engineers: Responsible for building and managing CI/CD pipelines and production environments for stateful applications.

• System Administrators: Who manage containerized infrastructure and need to handle backups, data migration, and persistence.

• Anyone working with stateful containerized applications like databases (MySQL, PostgreSQL), content management systems (WordPress), or logging stacks.

Course Objectives

Upon successful completion of this course, you will be able to:

• Differentiate Volume Types: Clearly explain the differences, pros, and cons of anonymous volumes, named volumes, and bind mounts.

• Manage Named Volumes: Create, manage, and share named volumes to ensure data persistence and collaboration between multiple containers.

• Utilize Bind Mounts: Effectively use bind mounts to link host directories into containers for development workflows and data backups.

• Implement Dockerfile Volumes: Use the VOLUME instruction in a Dockerfile to define persistent data locations for an image.

• Orchestrate Volumes with Compose: Configure and manage complex, multi-container volume strategies using Docker Compose for real-world applications.

Prerequisites

To succeed in this course, you must have:

1. Fundamental Docker Knowledge: You should be comfortable with basic Docker concepts and commands, including docker run, docker build, docker pull, and docker ps.

2. Working Docker Environment: You need an installed and functioning version of Docker and Docker Compose on your system to perform the hands-on labs.

3. Familiarity with the Command Line: Proficiency in using a terminal or command prompt is essential.
