Cache your organization’s custom images

Cache your organization’s custom images with Kubernetes Image Puller so that workspaces using organization-specific container images start without waiting for large image downloads.

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

Configure the Image Puller to pre-pull custom images.

kubectl patch checluster/eclipse-che \
    --namespace eclipse-che \
    --type='merge' \
    --patch '{
              "spec": {
                "components": {
                  "imagePuller": {
                    "enable": true,
                    "spec": {
                      "images": "NAME-1=IMAGE-1;NAME-2=IMAGE-2"
                    }
                  }
                }
              }
            }'

where:

images: The semicolon-separated list of images in name=image format.

Verification

Verify that the image puller is configured with the custom images:

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