Triggering iOS build/test job via Github pull request on CloudBees

Question

I would like Jenkins to comment whether a merge passes or fails (much like Travis CI) on Github pull requests. I understand this is a feature on BuildHive. However, I cannot find an option on BuildHive for using customer provided slaves. My question is twofold:

1. Is there an option to limit builds to customer provided slaves on BuildHive?
2. Is there a way I could enable comments on pull requests using DEV@cloud (the actual job must be run on a customer provided slave)? If so, could you point me in the right direction to get this set up?

Answer 1

DEV@cloud can validate pull request as BuildHive does, with some additional configuration. See http://wiki.cloudbees.com/bin/view/DEV/Github+Pull+Request+Validation

Answer 2

Answering in the order of your questions:

1. BuildHive uses the Validated Merge plugin for Git from Jenkins Enterprise to enable Jenkins to perform pull requests and run the builds before doing a push to the main repo. That said, currently you cannot use Customer Provided Executors with BuildHive.
2. DEV@cloud: Normally, all Jenkins Enterprise plugins are available in a paid tier of DEV@cloud. However, this plugin is not - as the plugin sets up a git server within Jenkins - not easily achievable in a cloud setup. I have created a ticket on CloudBees support requesting that the plugin be made available and the engineering team will investigate into delivering the feature.

Meanwhile, if you like you can use Jenkins Enterprise to use the feature (however it is an on-premises solution).
