Docker Overlay2 Storage Balloons to 400GB+ with Airflow-Spawned Containers
An operator running Docker with Airflow (which dynamically spins up many containers via DAGs) found the overlay2 storage driver accumulated 690 folders consuming over 400GB, saturating the server, with no clear built-in way to safely prune the folder. This reflects a common operational gap for teams running dynamic container workloads without a storage-cleanup strategy.

Similar Problems
surfaced semanticallyDocker BuildKit Cache Prune Command Hangs While Cache Objects Keep Growing
A developer reports that docker builder prune does not terminate and appears to create new BuildKit cache objects faster than it removes them, eventually filling the system disk. This affects developers relying on Docker BuildKit for image builds and signals a reliability gap in cache lifecycle management tooling.
Managing Docker Stack Separation Across Multiple Hosts Lacks Clear Guidelines
Homelab and self-hosted users running many Docker stacks struggle to decide when VM-level isolation is needed versus Docker-level separation. There is no clear framework or tooling to guide multi-host container architecture decisions at scale.
Container Registry Pulls Are Slow Due to Layer-Level Rather Than File-Level Deduplication
Container image distribution uses layer-level deduplication, which fails to eliminate redundancy within layers, resulting in unnecessarily large pull payloads. Teams on poor network connections — particularly robotics and edge deployment workflows — experience 80-90% slower pull times than file-level deduplication would allow. This is a structural architectural limitation of current container registry implementations.
No Unified Control Plane for Docker Containers Across Multiple Proxmox VMs and LXCs
Homelab users running Docker workloads across multiple Proxmox virtual machines and LXC containers face fragmented management — each host requires its own agent with no single dashboard for cross-host container orchestration. The gap between single-host tools and full Kubernetes is unaddressed for this segment.
Docker Daemon Networking Errors After Disk-Full Events Lack Explanation
A recurring Docker daemon error about only one connection being allowed appears sporadically, correlated with a prior disk-full event, and there is no clear documentation explaining its cause or resolution. This affects engineers running containerized build pipelines who are left debugging blind against opaque daemon internals.
