This document summarizes a design session on integrating Cloud Foundry with OpenStack at the OpenStack Summit in Paris. Key points discussed include requirements for the integration like static/floating IPs and security groups. The BOSH deployment process and Cloud Provider Interface for OpenStack were outlined. Ideas were proposed to query OpenStack from BOSH and generate Cloud Foundry manifest files, with the goal of discussing these proposals further on an Etherpad.

Cloud Foundry Overview
@Animesh Singh @Ferdy @ K_Bankole
!
Open Cloud Platform!
There is an increasing appetite for cloud-based
mobile, social and analytics
applications from line-of-business
executives - drives the need for a more
open cloud development platform!
Compelling Community !
Cloud Foundry has a compelling community
and emerging ecosystem as well as a mature
set of capabilities and robustness!

Cloud Provider Interface for OpenStack
• OpenStack CPI is an implementation of the BOSH CPI.!
• Leverages the Fog Ruby gem for OpenStack!
!
• OpenStack CPI gem (Ruby package), the OpenStack Registry and !
Agents all reside on the Cloud Foundry Bosh repository!

10. Before Deployment – What information we need from OpenStack
OpenStack Summit, Paris November 2014
@Animesh Singh @Ferdy @ K_Bankole
!
We need to get the following from OpenStack to enter in CF manifest!
!
!
!
Keypairs
Flavors
Networks
VM Subnet
DHCP IP
Gateway IP
Security groups
Should this be part of BOSH CPI ?!
!

11. Before Deployment - What all we need to setup on OpenStack?
OpenStack Summit, Paris November 2014
@Animesh Singh @Ferdy @ K_Bankole
!
We need to setup following on OpenStack (If it doesn't exist) :!
!
!
!
!
Create Keypair
Create Flavors
Router, DEA, Cloud
Controller, Service
Nodes
Create Security
Groups
Cf-private, cf-public
Setup tenant quota
Should this be part of BOSH CPI ?!
!

12. OpenStack Summit, Paris November 2014
Before Deployment – We need to create the manifest file
@Animesh Singh @Ferdy @ K_Bankole
!
We need to manually create the manifest file - hard and error prone!
!
!
!
Should this be part of BOSH CPI ?!
!

13. After Deployment – We need to handle lifecycle operations
OpenStack Summit, Paris November 2014
@Animesh Singh @Ferdy @ K_Bankole
!
Most of the lifecycle operations can be handled seamlessly, given that we understand the
current state of IaaS!
!
- Again the capability in BOSH to be able to query the IaaS in a live manner will help make
the transition from deployment to lifecycle operations much easier!
- Operations like changing the number of DEA instances, changing configuration sizes of
Cloud Foundry components, assigning new floating ips to components can all benefit
from a capability to query the live state of IaaS from a capacity perspective.!
- Some update operations do not work, for example assigning a new floating ip fails
because the old IP address needs to be detached first from a VM . We should either
provide an interface to detach floating ips, or a generic pluggable cleanup interface!
!
!

14. Summarizing Design Session Proposal - And Other Ideas ?
BOSH CPI Extension for !
- Querying OpenStack (IaaS) ?!
- Setting up OpenStack (IaaS)?!
- Generating Manifest ?!
- Cleaning up IaaS (e.g detach floating ips while assigning a new one) ?!
Other Ideas ?!
- CF on Docker containers in OpenStack ?!
- External CPI ?!
- Universal stemcell ?!
- Discover Services ?!
- Generate Service Broker templates ?!
