swift-cli

swift-cli provides pipelined streaming access to OpenStack Swift

It is designed for high speed transfer of large objects into and out of OpenStack Swift. Streaming support allows for usage like:

$ tar -czf - <my_dir/> | scli put <container>/<object>    
$ scli get <container>/<object> | tar -zx

Installation

swift-cli is written in Go and requires a Go installation. It can be installed with go get to download and compile it from source. To install the command-line tool, scli:

$ go get github.com/fanatic/swift-cli
$ go build -o scli github.com/fanatic/swift-cli

Usage:

version                   Print version information and quit
ls [container[/object]]   list containers or objects
put container[/object]    upload (put) an object
get container[/object]    download (get) an object
delete container[/object] delete an object
help [command]            Help about any command

Available Flags:
  -D, --debug=false: Enable debug mode

Set Swift keys as environment Variables:

$ export ST_AUTH=http://localhost:8080/auth/v1.0
$ export ST_USER=test:tester
$ export ST_KEY=testing

Odds and Ends

This is a WIP that does one thing relatively well: managing dynamic large objects in swift. Currently it only supports stdin and stdout.

Borrows upload logic from rlmcpherson's s3gof3r (https://github.com/rlmcpherson/s3gof3r)

Leverages the well-written golang swift library (http://github.com/ncw/swift)

Would probably be better to use Static Large Objects, but requires middleware support on the server.

I'd love to add "append" support to infinitely stream logs (update static manifest after every uploaded chunk and on ctrl+c) or to "concatenate" a file to an existing object.
