Overview of this book

Docker is an open source tool used for creating, deploying, and running applications using containers. With more than 100 self-contained tutorials, this book examines common pain points and best practices for developers building distributed applications with Docker. Each recipe in this book addresses a specific problem and offers a proven, best practice solution with insights into how it works, so that you can modify the code and configuration files to suit your needs. The Docker Cookbook begins by guiding you in setting up Docker in different environments and explains how to work with its containers and images. You’ll understand Docker orchestration, networking, security, and hosting platforms for effective collaboration and efficient deployment. The book also covers tips and tricks and new Docker features that support a range of other cloud offerings. By the end of this book, you’ll be able to package and deploy end-to-end distributed applications with Docker and be well-versed with best practice solutions for common development problems.

Removing an image

The docker image rm command lets you remove images from the Docker host. This command can remove one or more images, and you can specify images using one of the following identifiers:

  • The image's short ID.
  • The image's long ID.
  • The image's digest.
  • The image's name along with its tag. If the tag is not specified, then the latest tag is assumed by default.

If the image happens to have more than one tag associated with it, then those tags must be removed before removing the image. Alternatively, you can forcefully remove them using the -f or --force option of the docker image rm command. In such a case, all the tags will also be automatically removed.

Here is the syntax for the docker image rm command:

docker image rm [OPTIONS] IMAGE [IMAGE...]

In this recipe, we will create multiple tags for an image and demonstrate how to remove them.
