A presentation at Kubernetes Athens meetup in in Athens, Greece by Christos Gkoros
Kubernetes API Highlight Christos Gkoros API Designer @ Postman
API Design I work with engineering teams during their API Design phase: 1. Why we need this API? 2. Who consumes the API? 3. Make decisions about the API
API Design System ● ● ● ● ● Identify patterns that can be reused. Compare with well known APIs Document these patterns Promote their re-usability Incrementally establish a design system that produces consistent APIs
Let’s skip kubectl and other tools that aim to make things easy
● CORE - /api/v1 /api/v1/pods /api/v1/namespaces/… /api/v1/services ● GROUPS - /apis/{{group}}/{{versions}} /apis/apps/deployments/v1/ /apis/authentication.k8s.io/v1/ All these endpoints are documented in a definition available at /openapi/v2 Let’s see it in action! But first:
Authorization Inception: This will actually use the POST /apis/rbac.authorization.k8s.io/v1/clusterroles endpoint
DEMO TIME!!! A flow scaling our deployment based on external conditions (APIs) This is not intended production

This presentation explores the power of Kubernetes REST API in managing and orchestrating complex workflows within a Kubernetes cluster. We will dive into a practical use case of provisioning resources, demonstrating how to effectively leverage the Kubernetes REST API for this purpose. The session will include hands-on examples using Postman to interact with the Kubernetes API, making API calls to manage cluster resources. Additionally, we will introduce Postman Flows, a feature within Postman that allows for the orchestration of a sequence of API requests.
The following resources were mentioned during the presentation or are useful additional information.
