Duplicated kubernetes images #309

Closed afbjorklund closed 11 months ago

afbjorklund commented 1 year ago

The base image is not updated, but the kubernetes version is not pinned. So you end up with duplicate images.

The "pause" image is a separate issue, it is not properly updated in the configuration for the container runtime.

EDIT: reported separately as #314

Note: the kind project use the same tag for all releases, and only change the digest:

0.20.0: kindest/node:v1.28.0@sha256:b7a4cad12c197af3ba43202d3efe03246b3f0793f162afb40a33c923952d5b31

0.19.0: kindest/node:v1.28.0@sha256:dad5a6238c5e41d7cac405fae3b5eda2ad1de6f1190fa8bfc64ff5bb86173213

So you might want to consider including that digest as well... From the kind Releases
