PuppetConf 2016

GitHub's Puppet code base dates back to 2008 with over 250,000 lines of code, more than 60,000 commits, and over 200 committers. At GitHub, Puppet contributions come not only from infrastructure engineers, but also developers, database administrators, security administrators, and others for whom Puppet is not a primary skill. As the business has grown and staffing has increased, it has become even more important to have a rock-solid Puppet code base and deployment mechanism. The first part of this session will cover technical approaches to improve reliability including CI, developer tools, and integrations. The second part will describe cultural considerations including training, process, ChatOps, and code reviews to ensure best practices and avoid an "only ops writes Puppet" mentality.
