Docker Fundamentals
This course focuses on taking real applications from on premises, and then leveraging Docker to automate the deployment process into a containerised environment. You will learn how Docker actually works and how to manage and create images and then the related containers. You will see how to customise the network environment and how to access the filesystem from the containers. In addition you will see how to manage a docker repository and also how to create custom images from Dockerfiles.
Duration: 3 days
Who is it for: Developers, Devops engineers, cloud architects and developers who plan to work with Docker.
