When you run a containerized environment, you essentially create a read-write copy of that filesystem (docker image) inside the container. The image-base on which you create a container exists separately and cannot be altered. Once you create a container, it adds a writable layer on top of the immutable image, meaning you can now modify it. A container is, ultimately, just a running image. What you can do is use that template as a base to build a container. Since images are, in a way, just templates, you cannot start or run them. It allows developers to test and experiment software in stable, uniform conditions. This consistency is one of the great features of Docker. They represent an application and its virtual environment at a specific point in time. A Docker image is an immutable (unchangeable) file that contains the source code, libraries, dependencies, tools, and other files needed for an application to run.ĭue to their read-only quality, these images are sometimes referred to as snapshots. ![]()
