Real-world examples of custom resource usage

Popular tools like ArgoCD, Prometheus, and KubeVirt leverage custom resources to provide functionalities like GitOps, monitoring, and virtual machine management.

#3about 5 minutes

Understanding CRDs, operators, and code generators

Implementing a custom resource involves defining its schema with a Custom Resource Definition (CRD), writing the business logic in an operator, and using code generators for boilerplate client code.

Designing the MongoKube custom resource for automation

The first step in creating a custom resource is designing its specification, as demonstrated by the MongoKube example for automating MongoDB deployments.

#5about 2 minutes

Defining the MongoKube schema with a CRD

A Custom Resource Definition (CRD) file is used to register the new resource's schema, scope, versions, and naming conventions with the Kubernetes API server.

#6about 3 minutes

Implementing the controller logic in Go

The controller contains the core logic that reacts to changes in custom resource objects, such as creating deployments and services when a new object is applied.
