Practical OneOps

By: Nilesh Nimkar

Overview of this book

Walmart’s OneOps is an open source DevOps platform that is used for cloud and application lifecycle management. It can manage critical and complex application workload on any multi cloud-based infrastructure and revolutionizes the way administrators, developers, and engineers develop and launch new products. This practical book focuses on real-life cases and hands-on scenarios to develop, launch, and test your applications faster, so you can implement the DevOps process using OneOps. You will be exposed to the fundamental aspects of OneOps starting with installing, deploying, and configuring OneOps in a test environment, which will also come in handy later for development and debugging. You will also learn about design and architecture, and work through steps to perform enterprise level deployment. You will understand the initial setup of OneOps such as creating organization, teams, and access management. Finally, you will be taught how to configure, repair, scale, and extend applications across various cloud platforms.

Inductor and its structure


Inductor, as explained earlier, forms the link between the design and deployments. The inductor is responsible for collecting the two types of order, WorkOrder and ActionOrder, from the controller from various queues by zone. It then executes various actions based on the type of order. Remember that WorkOrder always results in a physical change of a CI-like deployment or in a teardown of CI, whereas ActionOrder will result in the change of the state of a CI-like stop, start, or restart. The inductor consumes these orders and acts on them by executing them either locally or remotely. The local execution is done via an Chef-solo cookbooks, and the remote execution is handled via SSH Chef-solo execution.

By default, the inductor component gets installed in /opt/oneops/inductor.

Although you can set up your own inductor, it is highly recommended that you retain the default inductor setup that comes with OneOps. A single inductor can manage multiple clouds and multiple...
