Docker Remove Tag - Shell/Bash

Introduction

Docker is an open-source platform that enables developers to develop, ship, and run applications in containers. One of the key features of Docker is the ability to tag images with version numbers, allowing developers to easily deploy and maintain different versions of their applications. However, with time, tags can become cumbersome to manage, especially when dealing with large application environments. In such cases, it becomes necessary to remove existing tags to free up space and maintain the organization of images.

In this article, we will discuss how to remove a Docker tag using the Shell/Bash commands.

Prerequisites

Before we begin, ensure that Docker is installed on your system. You can download and install Docker here.

Removing a Docker Tag

To remove a Docker tag from an image, follow these steps:

1. First, list all the available images on your system using the following command:

docker images

2. Next, use the following command to remove the tag:

docker rmi <image name>:<tag name>

For example, if you want to remove the v1 tag from the my-image image, you would run the following command:

docker rmi my-image:v1

This will remove the v1 tag from the my-image image.

Alternatively, you can also use the following command to remove all tags associated with an image:

docker rmi <image name>

For example, to remove all tags associated with the my-image image, you would run the following command:

docker rmi my-image

Conclusion

Docker tags can become difficult to manage over time, especially when dealing with large application environments. Removing unused tags can help free up space and maintain the organization of images. In this article, we discussed how to remove a Docker tag using Shell/Bash commands. With this knowledge, developers can maintain a clean and organized Docker environment.
