I wanted to try docker API without binding it on a TCP socket. Curl doesn't work on UNIX socket, so I've developped that:

go get github.com/Soulou/curl-unix-socket

./curl-unix-socket unix:///var/run/docker.sock:/v1.6/images/json

• -X: HTTP Verb [GET|POST|DELETE|...]
• -d: Request data
• -H: Additional Headers
  • Example: -H 'Accept: application/json|Content-type: application/json'
• -b: Add Cookie
  • Example: -b 'Key=Value|Key2=Value2'
• -v: Verbose
