Crossplane Integration

ScraperRelationship

Mission Control integrates with Crossplane to provide visibility into your infrastructure-as-code. Use it to:

  • Discover Crossplane managed resources and composite resources (XRs)
  • Build relationships between Providers and their managed resources
  • Link XRs to their composed resources and underlying cloud infrastructure
  • Track health and status changes of Crossplane resources
  • Correlate Crossplane configurations with AWS, Azure, or GCP resources via external IDs

How It Works​

Mission Control's Kubernetes scraper (kubernetes.go) automatically detects and handles Crossplane resources by:

  1. Identifying Crossplane resources through their API group - any resource with an apiVersion containing .upbound.io or .crossplane.io is treated as a Crossplane resource.

  2. Categorizing them with a special "Crossplane::" type prefix instead of the standard "Kubernetes::" prefix to distinguish them from regular Kubernetes resources.

  3. Building relationships between:

    • Crossplane managed resources and their providers
    • Crossplane composite resources (XRs) and their composed resources
    • Crossplane resources and their underlying cloud infrastructure

Resource Relationships​

The scraper automatically establishes relationships between:

  • Crossplane Providers and their managed resources
  • Composite Resources (XRs) and their composed resources
  • Crossplane managed resources and their cloud provider equivalents (e.g. AWS RDS instances)

The relationships are created through:

  1. Owner references on managed resources pointing to their providers
  2. Cross-references between XRs and composed resources
  3. Cloud provider specific external IDs linking to actual cloud resources

Scraping and Monitoring​

The scraper:

  • Watches for changes to Crossplane resources through the Kubernetes event stream
  • Tracks health and status of Crossplane resources
  • Maps relationships between components
  • Provides visibility into the full stack - from Crossplane CRDs down to cloud resources

This enables Mission Control to provide a complete view of your Crossplane-managed infrastructure with proper relationship mapping and real-time updates.
