CloudStack Auto Scale Interactive

Python interactive script to perform autoscale functions with Apache Cloudstack API.

Using Python client library for the CloudStack User API v3.0.0. For older versions, see the https://github.com/jasonhancock/cloudstack-python-client/tags.

Script Setup

Create the virtualenv environment, preferably with python 2.7.x, and install python packages.

$ mkvirtualenv CloudstackAutoScale
$ workon CloudstackAutoScale
$ pip install -r requirements.txt

You need to create the properties file to setup the script with parameters to access cloudstack api and to define the zone that you wish to auto scale.

cat << EOF > properties
[ConfigApi]
api: https://host:443/client/api
apikey: xxxxxx
secret: xxxxxx

[Envs]
zone: zonename
project: projectname
EOF

Executing Script

$ python CloudstackAutoScale.py -h
usage: CloudstackAutoScale.py [-h] -c COMMAND -o OPTION

Cloudstack Auto Scale script.

optional arguments:
  -h, --help            show this help message and exit
  -c COMMAND, --command COMMAND
                        counter, condition, policy, vmprofile or vmgroup
  -o OPTION, --option OPTION
                        list, create or delete
