Caching images for faster workspace start

To improve the start time performance of Che workspaces, use the Image Puller, a community-supported Che-agnostic component that can be used to pre-pull images for Kubernetes or OpenShift clusters.

This page is for platform administrators who install, configure, and manage Che on Kubernetes clusters. To learn more about common roles and example tasks referenced in Che documentation, see Common user roles and tasks.

The Image Puller is an additional Kubernetes or OpenShift deployment which creates a DaemonSet that can be configured to pre-pull relevant Che workspace images on each node. These images would already be available when a Che workspace starts, therefore improving the workspace start time.
