-## Run
-
-### Requirements
-
-The agent requires some privileges for getting access to container data, such as logs, performance counters and TCP sockets:
-* privileged mode (`securityContext.privileged: true`)
-* the host process ID namespace (`hostPID: true`)
-* `/sys/fs/cgroup` and `/sys/kernel/debug` should be mounted to the agent's container

-
-If you use [Prometheus Operator](https://github.com/prometheus-operator/prometheus-operator), 
-you will also need to create a PodMonitor:
-```yaml
-apiVersion: monitoring.coreos.com/v1
-kind: PodMonitor
-metadata:
-  name: coroot-node-agent
-  namespace: coroot
-spec:
-  selector:
-    matchLabels:
-      app: coroot-node-agent
-  podMetricsEndpoints:
-    - port: http
-```
-
-Make sure the PodMonitor matches `podMonitorSelector` defined in your Prometheus:
-```yaml
-apiVersion: monitoring.coreos.com/v1
-kind: Prometheus
-...
-spec:
-  ...
-  podMonitorNamespaceSelector: {}
-  podMonitorSelector: {}
-  ...
-```
-The special value `{}` allows Prometheus to watch all the PodMonitors from all namespaces.

-### Docker
-
-```bash
-docker run --detach --name coroot-node-agent \
-    --privileged --pid host \
-    -v /sys/kernel/debug:/sys/kernel/debug:rw \
-    -v /sys/fs/cgroup:/host/sys/fs/cgroup:ro \
-    ghcr.io/coroot/coroot-node-agent --cgroupfs-root=/host/sys/fs/cgroup
-```
-
-### Flags
-
-```bash
-usage: coroot-node-agent [<flags>]
-
-Flags:
-      --listen="0.0.0.0:80"  Listen address - ip:port or :port
-      --cgroupfs-root="/sys/fs/cgroup"
-                             The mount point of the host cgroupfs root
-      --no-parse-logs        Disable container logs parsing
-      --no-ping-upstreams    Disable container upstreams ping
-      --track-public-network=TRACK-PUBLIC-NETWORK ...
-                             Allow track connections to the specified IP networks, all private networks are allowed by default (e.g., Y.Y.Y.Y/mask)
-      --provider=PROVIDER    `provider` label for `node_cloud_info` metric
-      --region=REGION        `region` label for `node_cloud_info` metric
