# This script is used to update kind node image digests in the file:
|
|
# ./make/kind_images.sh.
|
|
#
|
|
# Each Kind release is accompanied by a set of compatible "node" images, for a
|
|
# range of different Kubernetes versions.
|
|
# The digests of these compatible node images are included in the release notes
|
|
# on GitHub. They look like:
|
|
# kindest/node:${K8S_VERSION}@sha256:${DIGEST}
|
|
#
|
|
# This script parses the GitHub release notes, extracts the `kindest/node` image
|
|
# references, and saves them to a shell script in the form of environment
|
|
# variables so that the script can be sourced by other scripts which pull
|
|
# the images and execute `kind`.
|
|
# This mechanism is fragile and depends on the Kind release manager using a
|
|
# consistent form for the release notes.
|
|
# It can be made more robust if / when Kind
|
|
# [provide machine-readable list of images for release](https://github.com/kubernetes-sigs/kind/issues/2376).
