Containerized log collection: how to capture Docker and Kubernetes logs before they disappear

Key takeaways Container logs share the container’s lifecycle. The Kubernetes documentation states that when a pod is evicted from a node, it removes the containers along with their logs. Container lifespans keep shrinking. Sysdig’s 2025 Cloud-Native Security and Usage Report found that 60% of containers live for 60 seconds or less. Collection has to be continuous, not scheduled. A node-level agent (a DaemonSet on Kubernetes) covers every container on a node without changing your applications.
