Crossplane Has a Free API: Build Your Own Cloud Platform with Kubernetes

Why Crossplane Changes Everything

Crossplane turns your Kubernetes cluster into a universal cloud API. Define custom platform APIs, provision AWS/GCP/Azure resources, and compose infrastructure — all through kubectl.

Install

helm repo add crossplane-stable https://charts.crossplane.io/stable
helm install crossplane crossplane-stable/crossplane \
  --namespace crossplane-system --create-namespace

Provision Cloud Resources

apiVersion: s3.aws.upbound.io/v1beta1
kind: Bucket
metadata:
  name: my-bucket
spec:
  forProvider:
    region: us-east-1

kubectl apply -f bucket.yaml
kubectl get bucket my-bucket
