Chapter 7: Understanding the Core Components of a Kubernetes Cluster

Kubernetes, at the time of writing, is the mayor Container orchestrator in the market.
Kubernetes is composed of the binaries that make up the cluster, and the logical objects called API objects.
Kubernetes API objects are the logical objects managed by the orchestrator.
We can run orchestrated containarized workloads.
A container orchestrator is a tool in charge of managing our running containers and different tasks related to keeping our workloads highly available.
A Pod is the smallest logical object of Kubernetes that encapsulates one or more containers in shared namespaces.
A Deployment is a set of replicated Pods that are managed by the Kubernetes replication controllers.

Flores

Esteban Flores has been meddling with computers since he was 8 years old. His life as an IT expert began when he lost a lot of important data belonging to his family by saying he was "fixing the computer." He's worked for top-tier companies, including Hewlett-Packard Enterprise, VMware, Akamai, and Microsoft. With 10 years' experience, his passion for cutting-edge technology has driven him to work on different roles during his professional career. Storage technologies have always been his forte, focusing mostly on performance tuning and optimization. A photographer during his free time, he's been doing Linux-related things since his first job, finding amazement in its flexibility to run from a small laptop all the way up to the world's fastest supercomputers.
