~ Getting started ~
# Install the gem.
>> sudo gem install cloud-crowd
# Install the CloudCrowd configuration files to a location of your choosing.
>> crowd install ~/config/cloud-crowd
# Now, you can use the full complement of `crowd` commands from inside of
# this configuration directory. To see the available commands:
>> crowd --help
# Edit the configuration files to your satisfaction, add AWS credentials,
# and then load the CloudCrowd schema into your configured database.
>> mate ~/config/cloud-crowd/config.yml
>> mate ~/config/cloud-crowd/database.yml
>> crowd load_schema
# Write your actions, and install them into the 'actions' subdirectory.
# CloudCrowd comes with some default actions as an example.
# To launch the central server (make sure that you include its location
# in config.yml), either:
>> crowd server
# or:
>> thin -R config.ru --servers 3 -e production start
# Any server that supports Rack should work with the rackup file.
# Then, to spin up 10 workers:
>> crowd workers start -n 10
# To spin up workers remotely, install the 'cloud-crowd' gem, and copy over
# your configuration directory.
# At this point you can visit your server console at localhost:9173 to
# view all of your workers, ready for action.
