# 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:



| Cloud Providers  | vms    | nics    | discs     | images   | pips    | stacks   |

|------------------|--------|---------|-----------|----------|---------|----------|

| Amazon EC2       | ✓| ✓ | ✓   |  ✓ |  ✓|  ✓ |

| Microsoft Azure  | ✓| ✓ | ✓   |  ✓ |  ✓|  **NA**  |

| Google Cloud     | ✓| ✓ | ✓   |  ✗ |  ✗|  **NA**  |

| VMWare           | ✓| ✓ | ✓   |  ✗ |  **NA** |  **NA**  |



* RedHat Enterprize Virtualization Manager - RHEV (_Support yet To be added_)

* RedHat Openstack (_Support yet To be added_)

* OCP Clusters deplyed on Public clouds (_Support yet To be added_)



NOTE: You can use `--all` flag with all the cloud providers to clean all supported resources.



The list of resource types it helps to clean could be found under settings.yaml.template](https://github.com/RedHatQE/cloudwash/blob/master/settings.yaml.template) file for individual cloud providers along with cleanup criteria.



## Installation



User can run `cloudwash` multiple ways:

- [PiP Package Installation](#pip-package-installation)

- [Docker Image Installation](#docker-image-installation)

- [OC BuildConfig Installation](#oc-buildconfig-installation)



### PiP Package Installation



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:



```

$ mkdir ~/cloudwash && cd ~/cloudwash

$ pip install cloudwash

```



### Docker Image Installation



#### From Container image registry

The [container image](https://quay.io/repository/redhatqe/cloudwash) for cloudwash is available in quay. This image provides the cloudwash installed from released python package with release version tags. Latest tag always points to the latest released version tag.



#### Build from local DockerFile

This github repo contains a DockerFile, use any container building service to build from the dockerfile:



Build container from `Dockerfile.dev` that should build a container from the cloudwash github master branch giving the access to pre-released features.



### OC BuildConfig Installation

This github repo provides the ready to use BuildConfig on OCP / Kubernetes. The build config should create buildconfig to build master branch based container image. Use the image to build cloudwash pod.



## Configuration



The `cloudwash` uses the `DynaConf` configuration python module to access the data in `settings.yaml` or conf directory settings, it also 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"

```



#### Configuration with PyPi package:



Copy/Download `settings.yaml.template` to local `~/cloudwash` directory as `settings.yaml`, update it with the cloud provider credentials and other configuration details for successful resource reporting and cleanup.



#### Configuration with cloudwash container images:



_Either_ - The docker images have `settings.yaml` added from Dockerfile. Build the container from the image, access the container and update the `settings.yaml` with real values and commit the changes to the image. Use the commited image for cleanup activity.



_Or_ - Export/Set the environment variables for all or only sensitive credentials as shown above. The dynaconf in cloudwash container should read these credentials from environment variable.



## Usage Examples



* Cleanup Help:



```

# swach --help



Usage: swach [OPTIONS] COMMAND [ARGS]...



A Cleanup Utility to remove cloud resources from cloud Providers!

--help Show this message and exit.



Commands:

azure		Cleanup Azure provider

aws			Cleanup Amazon provider

gce			Cleanup GCE provider

openstack	Cleanup OSP provider

rhev 		Cleanup RHEV provider

vmware 		Cleanup VMWare provider

```



* Cleanup Cloud Provider help:



```

# swach azure --help



Usage: swach azure [OPTIONS]



  Cleanup Azure provider



Options:

  --all             Remove all unused Resources from the provider

  --all_rg          Remove resource group only if all resources are older than SLA

  --nics            Remove only unused NICs from the provider

  --discs           Remove only unused DISCs from the provider

  --vms             Remove only unused VMs from the provider

  --pips            Remove only PiPs from the provider

  --help            Show this message and exit.



```



* Cleanup Dry Run (Monitor only mode using option `-d`):



```

# swach -d azure --all



<<<<<<< Running the cleanup script in DRY RUN mode >>>>>>>

The AZURE providers settings are initialized and validated !



=========== DRY SUMMARY ============



VMs:

	Deletable: ['test-bvhoduliam']

	Stoppable: ['foremanqe-nightly2']

DISCs:

	Deletable: ['test-bvhoduliam-osdisk']

NICs:

	Deletable: ['test-axodawttrw-nic0']

PIPs:

	Deletable: ['test-axodawttrw-pip0']

====================================

```



* Actual Cleanup Run:



```

# swach azure --all



<<<<<<< Running the cleanup script in ACTION mode >>>>>>>

The AZURE providers settings are initialized and validated !
