Review the default images cached by Image Puller

Review the default list of images used by Kubernetes Image Puller to decide which images to pre-cache. This list helps administrators configure Image Puller to use only a subset of these images in advance.

Prerequisites

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

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

Procedure

  1. Find out the namespace where the Che Operator is deployed:

    OPERATOR_NAMESPACE=$(kubectl get pods -l app.kubernetes.io/component=che-operator -o jsonpath={".items[0].metadata.namespace"} --all-namespaces)

  2. Find out the images that can be pre-pulled by the Image Puller:

    kubectl exec -n $OPERATOR_NAMESPACE deploy/che-operator -- cat /tmp/external_images.txt
