Janitor is a Linux component to perform quota management tasks to an Openstack tenant.
It is not an official Openstack's tool, and Janitor's code is wrapping Openstack python client libraries:
- python-openstackclient to manage authentication and as general API
- python-neutronclient to manage network
- python-novaclient to manage compute nodes and vms
- python-glanceclient to manage cloud images
- python-cinderclient to manage volumes and block storage
- Motivation
- Quick links
- Running in docker
- Install and usage
- Setup your dev environment
- Running janitor functional tests
- Contributing
- release pypi package
- Build RPM and release
- DEMO

I have been using OpenStack continuously since 2014 as a resource to run workloads with the main purpose of
testing software. Manage a healthy Openstack tenant quota is vital when working with CI/CD and a large number of
automated pipelines which run 24/7. A long time ago I and my team were having a lot of headaches with one of internal
Openstack the cluster which at that time had a very limited quota and workload capacity but was important for the
test workflow. With the constant false-positive for test failing due to lack of public/floating IP, storage/volume,
and even virtual CPU when provisioning new VMs, we got the idea of implementing Janitor, a super simple script/codes
to automate the clean-up task of deleting left-over virtual machines as well network and volume from an Openstack tenant, all managed by API and remote calls.

Running from your local machine, you can generate your own RPM running:
$ make rpm
if your environment is properly setup you should have your RPM at: /home/user/git/janitor/rpmbuild/RPMS/x86_64/janitor-0.0.2-0.x86_64.rpm
janitor is being built on Fedora Copr https://copr.fedorainfracloud.org/coprs/eduardocerqueira/janitor/builds/
running a new build you need to check your ~/.config/copr-fedora file and run:
make build
Before starting the release process, check your account permissions in Copr.
$ make srpm
- copy rpmbuild/SRPMS/janitor-0.0.2-0.src.rpm to janitor/copr
- push janitor/copr to github
copr-cli will be used, installed by sudo yum/dnf install copr-cli and configure it.
Request as Builder for projects janitor, wait until admin approves.
$ copr-cli build janitor https://github.com/eduardocerqueira/janitor/raw/master/copr/janitor-0.0.2-0.src.rpm
Go and grab a cup of tea or coffee, the release build will be come out soon ::

It is happening because python-requests lib is needed on version requests>=2.14.2 required by python-keystoneclient when I ran:
yum provides python-requests
the latest version I got was 2.11 that still don't satisfacts.

The trick here was, forcing reinstall requests using pip:
pip install requests --upgrade
