cloudwash 0.1.1

The cloud resources cleanup utility

cloudwash

Introduction

cloudwash is a library written in python that can be used to monitor and remove the unused cloud resources in public and private cloud providers.

Most importantly, cloudwash provides the CLI utility called 'swach' that can be used to fire commands to cleanup the resources on cloud.

cloudwash supports following cloud providers:

• Amazon EC2
• Google Cloud
• Microsoft Azure
• RedHat Enterprize Virtualization Manager - RHEV (Provisioned)
• RedHat Openstack (Provisioned)
• VMWare vCenter (Provisioned)

The list of resources it helps to clean are:

• VMs
• Network Interfaces
• Public IPs
• Disks

Installation

cloudwash can be installed via pip once you clone this git repository locally. It is always a good idea to use virtualenv to install pip packages.

For Linux Users, Depending on the distribution you are using, you may need to install following packages (or similar for your distribution of linux):

• libcurl-devel
• openssl-devel
• libxml2-devel
• libxml2-static
• gcc

Pycurl is a one of the dependent package of cloudwash that wants you to install above dependencies. Read more about it http://pycurl.io/docs/latest/install.html

Installation:

# git clone https://github.com/RedHatQE/cloudwash.git
# cd cloudwash
# pip install .
# cp settings.yaml.template settings.yaml

Configuration

To use this tool one needs to copy the settings.yaml.template to settings.yaml as instructed in Installation section above. Then, edit the settings.yaml and feed all the configuration needed to connect with the cloud providers as clients.

cloudwash uses the DynaConf configuration python module to access the data in settings.yaml and it allows an unique way of declaring secrets via Environment variables instead of putting in plain settings.yaml.

e.g: The Azure password field can be set via environment variable by exporting the environment variable

# export CLEANUP_PROVIDERS__AZURE__PASSWORD = myPa$$worb"
