Installation

Prerequisites

cloudify-system-tests should be installed in editable mode in the relevant virtualenv.

Installing The Code

$ pip install https://github.com/dankilman/claw/archive/master.tar.gz

Note

claw is updated quite frequently at the moment, so you may want to consider cloning the claw repo, and installing it in editable mode. This way, updates will be as easy as git pull in the repo local directory.

Setting Up The Environment

1. Choose a location that will serve as the base directory for all claw related configuration and generated files. For example:

   $ export CLAW_HOME=$HOME/claw
   $ mkdir -p $CLAW_HOME
   

2. Initialize claw in the base directory. While we run init in a specific directory, note that initialization is only performed once, i.e. the init configuration will be stored in ~/.claw and subsequent claw commands can be executed from any directory, not specifically the directory in which init was performed.

   $ cd $CLAW_HOME
   $ claw init
   

The init command created two files: suites.yaml and blueprints.yaml which are covered in their own sections. It also created a directory named configurations which is where generated manager blueprint configurations will be placed and a directory named scripts prepopulated with an example script.

It will make sense to have the base directory managed by some version control system (i.e. git, privately, as these configuration files will probably contain credentials, etc...)

The next sections go into details showing how claw may be useful in simplifying your day to day interactions with Cloudify.
