Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Get node binary (node.exe) from http://nodejs.org/download/
Create the folder where node will reside and move node.exe to it
Download the last zip version of npm from http://nodejs.org/dist/npm
Unpack the zip inside the node folder
Download the last tgz version of npm from http://nodejs.org/dist/npm
Open the tgz file and unpack only the file bin/npm (without extension) directly on the node folder.
Add the the node folder and the packages/bin folder to PATH
On a command prompt execute npm install -g npm to update npm to the latest version

Now you can use npm and node from windows cmd or from bash shell like Git Bash of msysgit.
