KubeArmor supports following types of workloads:
- K8s orchestrated: Workloads deployed as k8s orchestrated containers. In this case, Kubearmor is deployed as a k8s daemonset. Note, KubeArmor supports policy enforcement on both k8s-pods (KubeArmorPolicy) as well as k8s-nodes (KubeArmorHostPolicy).
- Containerized: Workloads that are containerized but not k8s orchestrated are supported. KubeArmor installed in systemd mode can be used to protect such workloads.
- VM/Bare-Metals: Workloads deployed on Virtual Machines or Bare Metal i.e. workloads directly operating as host/system processes. In this case, Kubearmor is deployed in systemd mode.
