Storage on Worker Hosts
A worker host's root disk provides storage for host configuration files, local Docker images, and hosted container's ephemeral filesystems.
Note
On Simplex or Duplex systems, worker storage is provided using
resources on the combined host. For more information, see Storage on Controller Hosts
<storage-planning-storage-on-controller-hosts>.
Root filesystem storage
Space on the root disk is allocated to provide filesystem storage.
You can increase the allotments for the following filesystems using the Horizon Web interface or the CLI. Resizing must be done on a host-by-host basis for non- synced filesystems.
- Docker Storage
-
The storage allotment for the Docker image cache for this host, and for the ephemeral filesystems of containers on this host.
- Kubelet Storage
-
The storage allotment for ephemeral storage related to Kubernetes pods on this host.
- Scratch Storage
-
The storage allotment for a variety of miscellaneous transient host operations.
- Logs Storage
-
The storage allotment for log data. This filesystem is not resizable. Logs are rotated within the fixed space as allocated.
