Gitlab CI (Continuous Integration)

Layer A set of read-only files or commands that describe how to set up the underlying system beneath the container. Layers are built on top of each other, and each one represents a change to the filesystem.
Image An immutable layer that forms the base of the container.
Container An instance of the image that can be executed as an independent application. The container has a mutable layer that lies on top of the image and that is separate from the underlying layers.
Registry A storage and content delivery system used for distributing Docker images.
Repository A collection of related Docker images, often different versions of the same application.
