Command line client for Carina by Rackspace, a container service that's currently in Beta.
There are downloads of the built binaries over in releases.
After downloading the version for your system, you'll probably need to rename it,
set it as executable, and put it on a PATH you have:
$ mv carina-darwin-amd64 ~/bin/carina
$ chmod u+x ~/bin/carina$ mv carina-linux-amd64 ~/bin/carina
$ chmod u+x ~/bin/carina> carina.exe
$ export CARINA_USERNAME=trythingsout
$ export CARINA_APIKEY=$RACKSPACE_APIKEY
$ carina list

mycluster container1-4G 1 false active
$ carina create newone
newone container1-4G 1 false new
$ carina create another --wait --autoscale

The build script assumes you're running go 1.5 or later. If not, upgrade or use something like gimme.
make carinaThis creates carina in the current directory (there is no make install currently).
If you want it to build on prior releases of go, we'd need a PR to change up how
the Makefile sets the LDFLAGS conditionally based on Go version.
The release script relies on github-release. Get it, configure it.
Make sure you're on master then run release.sh with the next tag and release name.
./release.sh 0.2.0 "Acute Aquarius"How do you pick the release name?
The hardest problem in computer science is picking names. For releases, we take an adjective attached combined with the next constellation from an alphabetical list of constellations. It can be alliterative if you like.
