Docker is a powerful tool for creating, distributing, and running containers. One of the basic commands that helps you view the existing images on your system is the docker image ls command. By using this command, you can see a list of all the images that are present on your system. This can assist you in better managing your images and deciding which images should be removed or updated.
When you need to use a container, ensure that you have the right images. The docker image ls command allows you to see images that you have previously downloaded or your local images. You can also get information such as ID, name, and tag for each image that may help you choose better options for deployment or removal of images.
You might wonder when to use this command. A good suggestion is to use it before starting on a new project or after new images have been installed. This can help you have an accurate picture of the current status of your images and prevent issues that might arise from image conflicts.
In general, if you intend to keep your images up to date, you can use this command as a tool for auditing older images and scheduling their removal or updates. Keep in mind that it’s always best to remove unused images to free up disk space for new projects and images.
