This code cleans up a Docker system by removing all unused images, containers, networks, volumes, and build caches.

Run example

npm run import -- "Actually delete everything"

Actually delete everything

docker system prune -a

bash
#!/bin/bash

# Function to clean up unused Docker resources
clean_docker() {
  # Option to remove all unused data, including networks and volumes
  local -i confirm_remove_all=true

  # Ask user to confirm before proceeding
  while true; do
    read -p "Are you sure you want to remove all unused Docker data? (y/n): " confirm
    if [[ $confirm =~ ^[Yy]$ ]]; then
      break
    elif [[ $confirm =~ ^[Nn]$ ]]; then
      echo "Docker cleanup cancelled."
      return
    else
      read -p "Invalid input. Please enter 'y' or 'n': " confirm
    fi
  done

  # Remove all unused data
  docker system prune -a --force
}

# Call the function
clean_docker

This code snippet uses the docker system prune command with the -a flag to remove all unused Docker images, containers, networks, volumes, and build caches.

Here's a breakdown:

1. docker system prune:

   • This command is used to remove unused Docker resources.

2. -a:

   • This flag tells docker system prune to remove all types of unused resources, including images, containers, networks, volumes, and build caches.

In essence, this command cleans up your Docker system by removing any resources that are no longer in use.
