Version Databag - A Chef Release Process
April 4, 2017
At Cerner, we use Chef. In fact, we’re heavily ingrained with Chef in our configuration management practices. We deploy services from Tomcat to Kafka with Chef. Even the first open source project we announced was a tool for Chef! With all of this integration with Chef, we need a simple way to manage all of those versions. This is where the Version Databag cookbook comes in. At a high level, this cookbook allows us to define our versions in a centralized data bag (grouped under conceptual units) and populates the corresponding node attributes required with those versions at runtime.
