Crossplane is an open-source Kubernetes add-on that enables you to provision and manage cloud infrastructure (AWS, Azure, GCP, etc.) and services (databases, networks, queues) using Kubernetes manifests. It extends Kubernetes into a universal control plane, unifying application and infrastructure management.
 
This course provides hands-on training to set up Crossplane, configure providers, build composite resources, and manage multi-cloud infrastructure using a GitOps-friendly workflow. By the end, you’ll be able to define, deploy, and operate cloud infrastructure entirely within Kubernetes.
What You Will Gain

  • Understand Crossplane architecture and how it extends Kubernetes.

  • Install and configure Crossplane in your cluster.

  • Manage cloud resources (EC2, RDS, S3, etc.) via Kubernetes CRDs.

  • Build composite resources (XRs) and define infrastructure abstractions.

  • Integrate Crossplane with GitOps tools like ArgoCD and Flux.

  • Deploy multi-cloud applications using Crossplane providers.

  • Apply security, RBAC, and policies to infrastructure management.

Who This Course Is For

  • DevOps engineers managing infrastructure on Kubernetes.

  • Cloud engineers working across AWS, Azure, or GCP.

  • SREs building GitOps pipelines for infrastructure.

  • Developers needing self-service infrastructure provisioning.

  • Students & professionals preparing for cloud-native roles.

How to Use This Course Effectively

  1. Start with Kubernetes basics before diving into Crossplane.

  2. Install Crossplane on a local or managed cluster (e.g., Minikube, EKS).

  3. Experiment with providers (AWS, Azure, GCP).

  4. Practice with composite resources to abstract infrastructure.

  5. Deploy real workloads using Crossplane-managed infrastructure.

  6. Integrate GitOps for production-ready workflows.

Certification Back to Top

Learners will receive a Certificate of Completion from Uplatz, validating expertise in Crossplane and Kubernetes-native infrastructure management. This certification demonstrates skills for roles in DevOps, SRE, Cloud Engineering, and Platform Engineering.

Career & Jobs Back to Top

Crossplane expertise prepares learners for roles such as:

  • DevOps Engineer (Kubernetes + Infra as Code)

  • Site Reliability Engineer (SRE)

  • Platform Engineer (Internal Developer Platforms)

  • Cloud Infrastructure Engineer

  • Multi-Cloud Architect

Crossplane adoption is growing among enterprises adopting GitOps, platform engineering, and multi-cloud strategies, making it a career-boosting skill.

Interview Questions Back to Top

  1. What is Crossplane and how does it differ from Terraform?
    Crossplane is Kubernetes-native, managing infrastructure via CRDs. Terraform is external and CLI-based.

  2. What are providers in Crossplane?
    Providers are cloud integrations (AWS, Azure, GCP, etc.) that let Crossplane manage external resources.

  3. What are Composite Resources (XRs)?
    Composite Resources allow you to create higher-level abstractions of infrastructure, enabling self-service provisioning.

  4. How does Crossplane extend Kubernetes?
    By adding CRDs that represent cloud resources (e.g., RDS, S3, VPC) inside Kubernetes.

  5. What is the difference between XRDs and Compositions?

  • XRD (CompositeResourceDefinition): Defines the schema of a new resource type.

  • Composition: Maps the XR to actual cloud resources.

  1. How does Crossplane integrate with GitOps?
    Crossplane resources are YAML manifests, making them declarative and GitOps-compatible.

  2. What is the benefit of Crossplane over Helm charts for infrastructure?
    Crossplane provisions actual cloud resources (databases, VPCs) vs Helm, which only deploys Kubernetes workloads.

  3. How does Crossplane ensure security?
    By using Kubernetes RBAC, secret management, and policy enforcement to control infra access.

  4. Can Crossplane manage multi-cloud environments?
    Yes, Crossplane supports multiple providers simultaneously, enabling multi-cloud deployments.

  5. Where is Crossplane commonly used?
    In platform engineering, internal developer platforms, GitOps pipelines, and multi-cloud infrastructure management.
