How to fix Error response from daemon: conflict: unable to delete image (must be forced) - image has dependent child images in Docker

# Find the image ID of the parent image
docker images | grep <image_name>

# Search for child images by checking the Parent field
IMAGE_ID="<parent_image_id>"
for img in $(docker images -aq); do
  parent=$(docker inspect --format '{{.Parent}}' "$img" 2>/dev/null)
  if echo "$parent" | grep -q "$IMAGE_ID"; then
    echo "Child image: $img"
  fi
done

docker inspect --format='{{.Id}} {{.Parent}}' $(docker images -aq) | grep <parent_image_id>

# Delete a specific child image
docker rmi <child_image_id>

# If the child also has dependencies, repeat the process
# Delete in order from newest to oldest

# Example: if you have base -> app:v1 -> app:v2
docker rmi app:v2    # Delete newest first
docker rmi app:v1    # Then intermediate
docker rmi base      # Finally the parent

# List all tags for the image
docker images --format "{{.Repository}}:{{.Tag}}" | grep <image_name>

# Delete by specific tag
docker rmi myregistry/myimage:v1.0
docker rmi myregistry/myimage:latest

# This may untag without fully deleting if other references exist

#!/bin/bash
# Script to recursively delete an image and its children

delete_image_recursive() {
  local image_id=$1

  # Find all direct children
  for child in $(docker images -aq); do
    parent=$(docker inspect --format '{{.Parent}}' "$child" 2>/dev/null | sed 's/sha256://')
    if [[ "$parent" == "$image_id"* ]]; then
      echo "Found child: $child - deleting first"
      delete_image_recursive "$child"
    fi
  done

  # Now delete this image
  echo "Deleting image: $image_id"
  docker rmi "$image_id"
}

# Usage:
delete_image_recursive "<image_id>"

# Using Douglas Muth's script
bash <(curl -s https://raw.githubusercontent.com/dmuth/docker-remove-dependent-child-images/master/docker-remove-image) <IMAGE_ID>

# Force delete by image ID
docker rmi -f <image_id>

# Force delete by name
docker rmi -f myimage:v1.0

# Remove dangling images (untagged and unreferenced)
docker image prune

# Remove all unused images
docker image prune -a

# Remove all dangling images (untagged images not used by any container)
docker image prune

# Remove ALL unused images (not just dangling)
# This removes images not associated with any container
docker image prune -a

# Full system cleanup (images, containers, networks, build cache)
docker system prune -a

# Include volumes in cleanup (careful - data loss possible!)
docker system prune -a --volumes

docker image prune -a -f

# Check your Docker version
docker version

# BuildKit is default in Docker 23.0+
# For older versions, enable it explicitly:
export DOCKER_BUILDKIT=1
docker build -t myimage .

# Or in Docker daemon config (/etc/docker/daemon.json):
{
  "features": {
    "buildkit": true
  }
}
