Defining the list of images to pull
The Image Puller can pre-pull most images, including scratch images such as che-machine-exec
. However, images that mount volumes in the Dockerfile, such as traefik
, are not supported for pre-pulling on OpenShift 3.11.
Procedure
-
Gather a list of relevant container images for prepulling by navigating to the
https://<che_fqdn>/plugin-registry/v3/external_images.txt
URL. -
Determine images from the list for pre-pulling. For faster workspace startup times, consider pre-pulling workspace related images such as
che-theia
,che-machine-exec
,che-theia-endpoint-runtime-binary
, and plug-in sidecar images.
