This is because, when you make changes to a layer in your image, Docker not only rebuilds that particular layer, but all layers built from it. Thus, you should organize layers that change most often as high up the stack as possible.

The hierarchy of your layers is key to efficient lifecycle management of your Docker images.

These layers form a series of intermediate images, built one on top of the other in stages, where each layer is dependent on the layer immediately below it. Image LayersД®ach of the files that make up a Docker image is known as a layer. For now, though, letвЂ™s focus on the most important Docker image concepts. WeвЂ™ll cover these two methods in more detail later in this guide.

Dockerfile : By constructing a plain-text file, known as a Dockerfile, which provides the specifications for creating a Docker image.

Interactive : By running a container from an existing Docker image, manually changing that container environment through a series of live steps, and saving the resulting state as a new image.

You can create a Docker image by using one of two methods: But first letвЂ™s look at the composition of a Docker image in more detail.ДЄ Docker image is made up of a collection of files that bundle together all the essentials вЂ“ such as installations, application code, and dependencies вЂ“ required to configure a fully operational container environment.

So, weвЂ™ll briefly cover how to create Docker images for deploying your code and assembling container-based services. So, in this introduction, weвЂ™ll not only take you through the basics of Docker images, but also show you where to find ready-made, off-the-shelf images that will give you a head start in building your own containerized applications, tools, and services.ДЄs a new Docker user, youвЂ™ll also need to understand how to build your own custom images. Docker images are also the starting point for anyone using Docker for the first time.

It provides a convenient way to package up applications and preconfigured server environments, which you can use for your own private use or share publicly with other Docker users. A Docker image is a read-only template that contains a set of instructions for creating a container that can run on the Docker platform.
