Cache default Che images on all nodes

Cache default Che images on all nodes by enabling Kubernetes Image Puller. The Eclipse Che Operator controls the list of images to pre-pull and automatically updates them on Che upgrade.

Prerequisites

  • Your organization’s instance of Che is installed and running on Kubernetes cluster.

  • Image Puller is installed on Kubernetes cluster.

  • An active kubectl session with administrative permissions to the destination Kubernetes cluster. See Overview of kubectl.

Procedure

  1. Configure the Image Puller to pre-pull Che images.

    kubectl patch checluster/eclipse-che \
    --namespace eclipse-che \
    --type='merge' \
    --patch '{
              "spec": {
                "components": {
                  "imagePuller": {
                    "enable": true
                  }
                }
              }
            }'
Verification

  • Verify that the image puller is enabled:

    kubectl get checluster eclipse-che -n eclipse-che -o jsonpath='{.spec.components.imagePuller.enable}'
