Name any of memory_limit, memory_request, cpu_limit and cpu_request: a Kubernetes quantity holds the member, an empty string stops holding it (which does not change what the agent runs: it keeps its current value, carried through upgrades), and an absent member is unchanged. Limits take memory 512Mi-16Gi and CPU 100m-8; requests are capped at memory 128Mi-2Gi and CPU 50m-2 because the agent's old pod stops before its replacement schedules. Every later agent upgrade and every install command renders the held sizing; an online agent that accepts it re-renders its own release at once and restarts onto it. The bearer twin of `ankra cluster agent resources set`. ## OpenAPI ````yaml https://platform.ankra.app/openapi.json put /api/v1/org/clusters/{cluster_id}/agent/resources openapi: 3.1.0 info: title: FastAPI version: 0.1.0 servers: - url: https://platform.ankra.app security: [] tags: - name: Organisation IAM description: >- Custom organisation roles and scoped role assignments for member and service-account identities. - 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: AWS Clusters description: >- Provision and manage self-managed k3s / kubeadm clusters on AWS EC2 in your own VPC. - name: Ankra Cloud Clusters description: >- Provision and manage self-managed kubeadm / k3s clusters on Ankra Cloud servers: a private network, a NAT router and a bastion per 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: Pipelines description: >- Pipeline definitions, the approval of the authority they declare, and the caches pipelines keep between runs. - name: Workspaces description: >- Personal workspaces on the organisation's CI pool where a repository's heavy commands run, and the repository profiles they are built from. - name: Deploy Targets description: >- Environments, the hosts registered to receive deployments, and the releases deployed to them. - name: Backups description: >- Backup vaults, restore points, protection posture and captures for stacks and application deployments; a completed capture is not a verified restore. - name: Stack Profiles description: Reusable stack definitions, their versions and sharing. - name: Services description: >- Versioned service packages and explicit sharing.
