Creation of Kubernetes operators Hand on experience Description

Creation of Kubernetes operators Hand on experience Description The goal of the webinar is to cover Kubernetes operators using Kubernetes Operator Pythonic Framework (kopf) by creating an operator capable of deploying two bigdatastack sub-components. The operator will deploy two pods and automatically create services allowing communication between them.

Kubernetes Operators are software extensions to Kubernetes that make use of custom resources to manage applications and their components. Use cases: ❏ ❏ ❏ deploying an application on demand taking and restoring backups of an application’s state handling upgrades of the application code alongside related changes such as database schemas or extra configuration settings publishing a Service to applications that don’t support Kubernetes APIs to discover them simulating failure in all or part of your cluster to test its resilience choosing a leader for a distributed application without an internal member election process

Triple monitoring engine’s use case - Deploy all TME’s components - Scale Prometheus : for each Prometheus instance created, a sidecar must be assigned, sidecar service must be created and added to Querier’s configuration.

Our demo - Deploy Prometheus’s instance Create Prometheus service Deploy Grafana instance Create Grafana service

Kubernetes Operators steps: - Create a Custom Resource Definition Create a Service Account Create a Cluster Role Binding Deploy the operator
