dockhand-lru-registry

dockhand-lru-registry acts as proxy to Distribution to make a registry with a cleanup policy based on least recently used tags. The registry keeps track of push/pull operations, monitors disk utilization and runs the registry garbage collector on a configurable schedule. When the registry exceeds the target disk utilization, a configurable percentage of the least recently used tags will be removed until disk utilization drops back below the target.

Garbage Collection

Garbage Collection can be scheduled and will turn the registry into read only mode via the proxy by only handling pulls while garbage collection is occurring.

Usage

See dockhand-charts for Kubernetes installation.

dockhand-lru-registry start --help
start the proxy with the provided settings
