Structure Of Docker Image
The layers of software that make up a Docker image make it easier to configure the dependencies needed to execute the container.
- Base Image: The basic image will be the starting point for the majority of Dockerfiles, and it can be made from scratch.
- Parent Image: The parent image is the image that our image is based on. We can refer to the parent image in the Dockerfile using the FROM command, and each declaration after that affects the parent image.
- Layers: Docker images have numerous layers. To create a sequence of intermediary images, each layer is created on top of the one before it.
- Docker Registry: Refer to this page on the Docker Registry for further information.
What is Docker Image?
Docker Image is an executable package of software that includes everything needed to run an application. This image informs how a container should instantiate, determining which software components will run and how. Docker Container is a virtual environment that bundles application code with all the dependencies required to run the application. The application runs quickly and reliably from one computing environment to another.
