sandboxed-container-helper performs health checks and operations and maintenance (O&M) on sandboxed containers in Container Service for Kubernetes (ACK) clusters. It provides two core capabilities: disk space monitoring through a Prometheus exporter, and unusual event reporting to kube-apiserver.
Features
Device Mapper disk space monitoring
sandboxed-container-helper exposes a Prometheus exporter that collects disk space metrics for volumes allocated by Device Mapper. Deploy ack-arms-prometheus in your ACK cluster to scrape these metrics, visualize them in Grafana dashboards, and configure alerts. For more information, see Enable ARMS Prometheus.
Unusual event reporting
sandboxed-container-helper detects and reports unusual events to kube-apiserver, including storage leaks, container data leaks, and orphaned pods. Deploy ack-node-problem-detector in your ACK cluster to collect and monitor these events. ack-node-problem-detector forwards events to configured sinks, including DingTalk, Log Service, and EventBridge. For more information, see Event monitoring.
Usage notes
sandboxed-container-helper is installed by default in ACK clusters. No additional configuration is required.
