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

Set up cmder to use msysgit / bash by default

Install cmder_mini (msysgit is already installed, so no need for full version)
In Cmder, open settings: Win + Alt + P
Under Startup > Tasks, add a task called {bash} with the following settings:
- Task parameters (set icon):
  - For Cmder icon: /icon "%CMDER_ROOT%\cmder.exe"
  - For Git icon: /icon "C:\Program Files (x86)\Git\etc\git.ico"
- Commands (open Git's bash shell):
"C:\Program Files (x86)\Git\bin\sh.exe" -l -new_console:d:%USERPROFILE%

I'm documenting my experience installing SourceFabric's open source radio station manager Airtime on a clean server Ubuntu 12.04 LTS (Precise Pangolin) server running the popular Virtualmin open-source domain manager.

Virtualmin is sufficiently generic that I imagine the results will be useful to anyone trying to install Airtime on Ubuntu 12.04.
