Cluster as Code: Applying 'As Code' Principles to Infrastructure Management

Explore a comprehensive approach to applying the 'as code' concept throughout the entire technology stack in this 35-minute presentation. Learn how to create disk images, set up bare metal clusters, and run services using source control, pull requests, and CI tools. Discover techniques for building OS images with Dockerfiles, 'unit testing' clusters, and provisioning using declarative DSL and immutable servers. Understand how Mesos and Marathon enable ephemeral and immutable nodes, allowing for task rescheduling as needed. Gain insights into reasoning about machine and cluster configuration, testing changes before deployment, and using pull requests for change tracking and auditing. The presentation covers topics such as high-level approach, curation tools, isolation, source control, setup agents, operating systems, verification, pain points, class definition, and changing master and enemy images.
