This Windows batch script removes all Docker images by iterating through a list of image IDs obtained from docker images -q and using docker rmi to delete each one.

Run example

npm run import -- "Delete images in cmd"

Delete images in cmd

FOR /f "tokens=*" %i IN ('docker images -q') DO docker rmi %i

bash
#!/bin/bash

# Remove all unused Docker images
UNUSED_IMAGES=$(docker images -q --format '{{.ID}}' | grep -v '^<none>')  # Filter out <none> images

# Print the images to be removed
echo "The following images will be removed:"
echo "$UNUSED_IMAGES"

# Prompt for confirmation before removing the images
read -p "Are you sure you want to remove these images? (yes/no): " -n 1 -r
if [[ $REPLY =~ ^[Yy]$ ]]; then
    docker rmi -f "$UNUSED_IMAGES"
    echo "Images removed successfully."
else
    echo "Image removal cancelled."
fi

This code snippet removes all Docker images from your system.

Here's a breakdown:

1. FOR /f "tokens=*" %i IN ('docker images -q'):

   • This is a Windows batch command that iterates over the output of the docker images -q command.
     • FOR /f is used to process text files, in this case, the output of the command.
     • "tokens=*" specifies that all tokens (words) in each line of the output should be captured.
     • %i is a variable that will hold the current token (image ID) in each iteration.
     • 'docker images -q' executes the command to list all Docker images and their IDs.

2. DO docker rmi %i:

   • This part of the command is executed for each image ID captured by %i.
     • docker rmi %i removes the Docker image with the ID stored in the %i variable.

In essence, this batch script efficiently iterates through all Docker images and removes them one by one.
