Who are we?Cisco

Cloud Security Engineers

Unholy dev/ops combo



Cisco Confidential


Why are we using Cloud Foundry?

We needed better tools

Consistent dev, test & prod environments

Custom built tooling outdated

Speed up development



Cisco Confidential


Starting out with Cloud Foundry

Trial and Error

Learning by debugging

“Borrowing” chunks of BOSH yaml.

Manually building and verifying CF deployments



Cisco Confidential

“I’ve got a running CloudFoundry system, and if you’ve ever tried to run CloudFoundry and BOSH, you may never have got to this point…”

Dr Nic Williams, CEO Stark & Wayne, CF Platform 2013


Cisco Confidential


The BOSH learning curve

Day 1: Why do I need BOSH?

Day 2: I don’t want to learn BOSH

Day 10: BOSH actually works...

Day 12: BOSH is Cool

Day 30: BOSH is Awesome

Day 50: I got to get me some more BOSH



Cisco Confidential

BOSH Deployed successfully...But does it work?


Cisco Confidential


We needed to reliably upgrade and test Cloud Foundry

Deploy, Test and Upgrade CF using Jenkins & BOSH

Separate CF manifest from environment manifest, merge with Spiff

Create new deployments using the same CF manifest, guarantee consistency

Project named C3CIJoint work between Cisco and CloudCredoAvailable on Github



Cisco Confidential


Abundance of CF Tests Available

Several Cloud Foundry test suites already available online

Older:

● YETI

● NYET

Newer:

● Smoke Tests

● CATS

We used the NYET and Smoke tests as they were the most reliable





BOSH + Jenkins + Spiff + NYET + Smoke = CF

C3CI JenkinsBOSH Release

Base CFmanifest

Environment specific manifest

CF BOSH Release





Consistency without development lockdown

Environment specific manifest

Prod Branch - Consistent base manifestOnly Environment specifics change

Dev Branch A Dev Branch B Dev Branch X

Branch allows development and testing of anypart of the deployment manifest

Base CF manifest



Cisco Confidential

Like an engine… Only with more moving parts




We needed to know what was going on insideCloud Foundry…

Without spending the evening with Wireshark.

Requirements

Monitor & graph the vitals of Cloud Foundry VMs deployed with BOSH.

Alert if a part of Cloud Foundry is degraded or offline.

Integrate with the tools used to monitor our other VMs.

- ELK

- Puppet-deployed Services





Enter Sensu!

Monitoring Cloud Foundry with Sensu

Sensu Client Job

CollectD Job

Cloud Foundry Job(s)


Individual VMs


Cisco Confidential


How the Sensu BOSH release works

Sensu Client BOSH release deployed along with CF-Release

Sensu Client, CollectD and Nagios checks installed on all BOSH VMs

Sensu checks and CollectD metrics pushed to Sensu Server over RabbitMQ

Small Python application runs as a Sensu Check to report Monit job health

Uchiwa GUI is used to display Sensu Alerts

Sensu routes metric data to Graphite for Graphing





Thanks for having us
