Environment Variables

Variable	Required	Default	Description
`Infra__Plugins__Host__Name`	Yes	—	Set to `Kubernetes`
`Infra__Plugins__Host__Version`	Yes	—	Plugin version (e.g., `0.8.0`)

No additional configuration is needed beyond the plugin name and version.

Service identity is derived from the HOSTNAME environment variable (injected by Kubernetes automatically) and POD_NAMESPACE (exposed via the Downward API). The service ID is formatted as namespace/hostname.

Resource limits (CPU and memory) are read from the Linux cgroup filesystem. Both cgroup v2 (/sys/fs/cgroup/cpu.max, /sys/fs/cgroup/memory.max) and cgroup v1 (/sys/fs/cgroup/cpu/cpu.cfs_quota_us, /sys/fs/cgroup/memory/memory.limit_in_bytes) are supported. CPU is reported in millicores and memory in MB.

Infrastructure

Deploy Notiway as a Kubernetes Deployment or StatefulSet.
Expose the pod namespace via the Downward API (the pod name is available by default via HOSTNAME; namespace requires an explicit fieldRef).
Set resource limits on the container so the cgroup values are populated.
