"It works on my machine" is one of the most expensive sentences in software delivery. Different dependency versions, different operating systems, different configurations between development and production quietly cost teams hours of debugging that has nothing to do with actual bugs. Docker exists to remove that variable entirely, and this course exists to make sure participants can use it properly.

Delivered by Arab British Fellowship Training Academy under the Information Technology and Programming category, the Packaging Applications the Right Way programme works through Dockerfile development, image layers, container registries, volumes, networking and Docker Compose — not as isolated commands, but as parts of a single, repeatable packaging and deployment process.

Participants learn to build lean, maintainable images, manage persistent data correctly, isolate workloads through networking, and coordinate multi-container applications with Compose. The emphasis throughout is on decisions that hold up in production: image size, build speed, security, and consistency between development, testing and live environments.

The course suits DevOps engineers, software developers, systems administrators, cloud engineers and anyone responsible for packaging, deploying or maintaining containerised applications within a corporate technology environment.

By the end of this programme, participants will be able to:

• Build and manage Docker images using well-structured Dockerfile configurations.
• Reduce image size and build time by understanding and optimising image layers.
• Configure containers for reliable deployment, isolation and operational management.
• Manage persistent application data through Docker volumes.
• Configure container networking for secure, reliable service communication.
• Use Docker Compose to define and manage multi-container application environments.
• Store, version and distribute images through a container registry.
• Improve application portability across development, testing, staging and production.
• Integrate Docker workflows into CI/CD and DevOps delivery pipelines.
• Apply governance and best practices to enterprise Docker operations at scale.
