What is the difference between a Docker image and a container? An image can be freely modified after launch, while a running container remains static and immutable. An image is an archive of the application's source code, while a container is a pre-built executable environment without code. An image resides in memory during operation, while a container is stored in a registry as layers. An image is an immutable template with a filesystem and metadata, while a container is an isolated process launched from an image with its own state.
