A production cluster reports exactly as it always has; a lower criticality needs a correspondingly larger blast radius before a finding reaches a severity that opens a ticket. ## OpenAPI ````yaml https://platform.ankra.app/openapi.json put /org/clusters/{cluster_id}/criticality openapi: 3.1.0 info: title: FastAPI version: 0.1.0 servers: - url: https://platform.ankra.app security: [] tags: - name: Clusters description: Create, inspect and manage clusters, and the stacks deployed on them. - name: Managed Clusters description: Provider-managed control planes, driven through one common surface. - name: Imported Clusters description: Clusters that already existed and were connected to Ankra. - name: Cluster Access description: Kubeconfigs, service-account tokens and per-cluster access grants. - name: Kubernetes description: Read and act on the Kubernetes objects inside a cluster. - name: DigitalOcean Clusters description: Provision and manage DigitalOcean Kubernetes clusters. - name: Hetzner Clusters description: Provision and manage Hetzner Kubernetes clusters. - name: OVH Clusters description: Provision and manage OVH Kubernetes clusters. - name: Scaleway Clusters description: Provision and manage Scaleway Kapsule clusters. - name: UpCloud Clusters description: Provision and manage UpCloud Kubernetes clusters. - name: Applications description: Deploy, configure and observe applications across the fleet. - name: Stack Profiles description: Reusable stack definitions, their versions and sharing. - name: Charts description: Browse the chart catalogue behind stacks and addons. - name: Helm description: Helm registries, credentials and the charts they expose. - name: Executions description: Long-running platform executions and their jobs. - name: Operations description: Cancel in-flight cluster operations and their jobs. - name: Chat description: Conversational sessions, plans and confirmable actions. - name: AI Agent Runs description: Autonomous agent runs and their outcomes. - name: AI Tickets description: The AI ticket board, its sync connections and settings. - name: AI Playbooks description: Reusable playbooks the AI lanes execute. - name: AI Conditions description: Conditions that gate AI autonomy. - name: AI Engineering Handoffs description: Work the AI lanes escalate to a human engineer. - name: AI Environment description: The environment and base stacks AI demos deploy into. - name: Security description: Findings, advisories, SBOMs, compliance and posture. - name: Cost description: Cluster and fleet cost, rate cards and cost settings. - name: Billing description: Subscription and spend caps. - name: Organisation description: Members, invitations, audit logs and organisation settings. - name: Account Tokens description: Personal access tokens for the API and CLI. - name: Credentials description: The shared credential store. - name: Azure Credentials description: Azure credentials and SSH keys. - name: DigitalOcean Credentials description: DigitalOcean credentials and SSH keys. - name: Hetzner Credentials description: Hetzner credentials and SSH keys. - name: OVH Credentials description: OVH credentials and SSH keys. - name: Scaleway Credentials description: Scaleway credentials. - name: UpCloud Credentials description: UpCloud credentials and SSH keys. - name: Data Source Credentials description: Credentials for metrics and log sources. - name: DNS Credentials description: Credentials for DNS providers. - name: DNS description: DNS zones and records, including custom organisation zones. - name: Cloudflare description: Cloudflare domains and the credentials behind them. - name: Variables description: Organisation- and cluster-scoped variables. - name: SOPS description: Encrypt and decrypt values with the organisation SOPS config. - name: Alerts description: Alert integrations and ingest credentials. - name: Notifications description: Notification routes and their delivery targets. - name: Support description: Support tickets. paths: /org/clusters/{cluster_id}/criticality: put: tags: - Clusters summary: Set what a cluster is for description: >- Records the cluster's criticality, the denominator the insight scanner grades blast radius against.
