In the previous chapter, we learned what containers are and how to run, stop, remove, list, and inspect them. We extracted the logging information of some containers, ran other processes inside an already running container, and finally we dived deep into the anatomy of containers. Whenever we ran a container, we created it using a container image. In this chapter, we will be familiarizing ourselves with these container images. We will learn in detail what they are, how to create them, and how to distribute them.
This chapter will cover the following topics:
- What images are?
- Creating images
- Sharing or shipping images
After completing this chapter, you will be able to do the following:
- Name three of the most important characteristics of a container image
- Create a custom image by interactively changing the container layer and committing it...
