About The Program

A Docker course teaches participants how to use Docker, an open-source platform for automating the deployment, scaling, and management of applications using containerization. It covers the fundamentals of Docker, containerization concepts, Docker networking, volumes, Docker Compose,, containerizing applications. The course aims to provide practical knowledge and skills to effectively use Docker for application development, deployment, and management.

Course Objective

Docker – DevOps Techlab – is leading the way as containers play a very vital role in the modern data-center today.
The core features this course covers includes: container creation and management and interacting with Docker hub, Docker file is used to create, manage and custom images, advanced Docker networking (how to safely expose container services, and link containers). Docker volumes to manage persistent data, and Docker Compose to build multi-container application Outcome.

Program Outcome

Upon completing a Docker course, participants will gain practical skills to:
• Understand Docker fundamentals and containerization concepts.
• Create, run, and manage containers using Docker.
• Utilize Docker networking and volumes for container communication and data persistence.
• Define and manage multi-container applications using Docker Compose.
• Containerize various types of applications effectively.
