INTRODUCING NINTU
VM Orchestration in the Era of DevOps Rodney Young, DevOps Engineer at Endgame
Nintu Overview
§ Devs: Guillermo Menjivar, Rodney Young, Michael Sheinberg
§ Written in python 2
§ Developed as a rest api to connect and orchestrate many other tools and platforms
§ Currently working with VMWare vCenter, but that is only a start
§ Looking to open source in the fall

About me
§ Liberal arts background (B.A. English/History; M.A. History) § Naturally, I went into a technical field § DevOps Engineer at Endgame
3
What Makes DevOps at Endgame Different?
§ Use a lot of custom solutions, in house developed tools, big data platforms, cloud technologies, and much more
§ Write more code than most devops groups § Not afraid to be bold, try new technology, fail fast and iterate § DevOps in the security field pushes edge cases and custom requirements § Tools we create actually get used § Have a bunch of fun

Repeated VM operations feel like…
It would be nice if…
§ One command could start as many VMs as you want
§ It didn’t matter what hypervisor you were using (VMWare, AWS, openstack…)
§ DNS got set up (if needed)
§ IPs got registered (if appropriate)
§ Service registry notified (hashicorp consul or similar)
§ Tear down just as easy
6
Prospective Use Cases
§ ephemeral VMs for Jenkins builds
§ stand up VMs and capturing metadata to feed automation systems (ansible or similar)
§ automated monitoring (freeipa / dns srv / Prometheus)
§ quick setup of proof of concept applications
§ orchestration of physical nodes (stacki with stacki rest)
7
Design Principles
§ Python micro-service with a restful API at the center § Extendable via calls from the restful API to other tools, such as consul, freeipa,
vmware, ec2… § Slim, easy to set up, easy to tweak and extend § Loosely coupled § An abstraction of existing APIs of useful tools like VMWare, EC2, freeipa, consul,
Prometheus, stacki… § Allow each tool to do what it does best, but provide a standard, single set of
endpoints to connect them with orchestration

Existing Tools?
§ Libcloud • Pysphere vs pyvmomi • Freeipa? • Built in rest?
§ Puppet, Salt, Chef, Terraform • Package – File - Service = J!! • Package – File – Service – Custom Module = K • Package – File – Service – (module that doesn’t work well) =
· salt://scripts/L.sh: cmd.script: - env: - BATCH: 'yes’ – IDEMPOTENT: ‘ihopeso’ § Platform specific tools
• Perl scripts for vmware • MS hyper-v / powershell

Concluding Thoughts
§ We hope to open source Nintu in the fall § If you are interested, follow Endgame’s blog for an announcement § At that point, we also hope you try it out and submit pull requests!
