gcrgc.sh cleans up tagged or untagged images pushed before specified date
for a given repository (an image name without a tag/digest).
USAGE:
gcrgc.sh REPOSITORY DATE
EXAMPLE
gcrgc.sh gcr.io/ahmet/my-app 2017-04-01
would clean up everything under the gcr.io/ahmet/my-app repository
pushed before 2017-04-01.

gcloud container images delete -q --force-delete-tags "${IMAGE}@${digest}"
)
let C=C+1
done
echo "Deleted ${C} images in ${IMAGE}." >&2
}

Pretty sweet script. Could I bother you to make a version that does this but KEEPs tagged versions?

i have a littel upgrade for LTS Images where you need to keep older stuff

COUNTALL="$(gcloud container images list-tags ${IMAGE} --limit=999999 --sort-by=TIMESTAMP  | grep -v DIGEST | wc -l)"
  for digest in $(gcloud container images list-tags ${IMAGE} --limit=999999 --sort-by=TIMESTAMP \
    --filter="timestamp.datetime < '${DATE}'" --format='get(digest)'); do

    if [ $(( $COUNTALL - $C )) -ge 10 ]
    then
      (
        set -x
        gcloud container images delete -q --force-delete-tags "${IMAGE}@${digest}"
      )
      let C=C+1
    else
      echo "Deleted $(( $C - 1 )) images in ${IMAGE}." >&2
      break
    fi   
  done

you could define how many Images should stay

@wibobm i ran into the same requirement. Its easy to accomplish by changing the filter in line 44 of the orinial script to:

--filter "NOT tags:* AND timestamp.datetime < '${DATE}'"
