Best practices around porting CF to RHEL/SLES?
|
Rishi Misra <misra.rishi@...>
Folks,
I am looking for some guidance around getting CF to work on RHEL/SLES. From my limited knowledge of CF I have gathered the following: - CF only supports Ubuntu trusty - CF consists of CCNG/GoRouter/DEA/Health Manager/CLI/UAA/Loggregator/BOSH repositories - CF is deployed using BOSH on IaaS - CF can be deployed on a local system using BOSH lite - BOSH/BOSH lite deployment of CF consists of pushing components listed above in a virtual machines (based on stemcells) - BOSH uses trusty stemcells to deploy CF components (?) My guess would be if I have to make this work in RHEL envt I would need to do the following: - Investigate if BOSH RHEL stemcell can be created - For each CF repositories try to see if it compiles and runs (associated test suites) on RHEL - Create release/deployment manifest based on existing CF manifest - Use BOSH/BOSH lite to deploy - Debug failures - ... Any tips greatly appreciated. Thanks in advance for your help.

Building RHEL 7 is very similar to building CentOS 7 and is supported by BOSH.

There are also official released CentOS 7 Stemcells: http://bosh.io/stemcells/bosh-aws-xen-centos-7-go_agent <http://bosh.io/stemcells/bosh-aws-xen-centos-7-go_agent> In order to use these you update what stemcell is being used in the CF Deployment Manifest. I would recommend you get your deployment working with CentOS 7 while working on building your custom RHEL 7 stemcells. The BOSH repository has instructions within it for how to build custom stemcells: https://github.com/cloudfoundry/bosh <https://github.com/cloudfoundry/bosh> ~Wayne Wayne E.

Specifically you want to look at the bosh-stemcell directory and use it’s Vagrantfile:

This is great .. thanks Wayne.
Does this mean CF already supports CentOS7? For some reason I thought it was Ubuntu trusty all the way. Is my understanding correct that when creating Stemcells for CF, I must also ensure that all CF components must first work on VMs with that Stemcell as its base? By "work" I mean it at least compiles and successfully runs associated testcases? Thanks again. On Wed, May 6, 2015 at 2:02 PM, Wayne E.

Cloud Foundry Elastic Runtime can only be deployed at this point on Ubuntu

Trusty stemcell. All components work of ER work on CentOS stemcell except the DEA (component that runs applications) due to certain incompatibilities with how containers are managed. Once CentOS 7.2+ is released that includes user namespacing, I believe there will be some effort to certify that full ER runs on CentOS/RHEL. RHEL stemcells can be built. See https://github.com/cloudfoundry/bosh/tree/master/bosh-stemcell for more details.

Thanks Dmitriy - I guess with DEA not working there won't be any

functioning CF on CentOS/RHEL. I wonder if SLES has better CF story at this point (in terms of porting)?
