How to get latest version of an image from artifact registry - google-cloud-platform

Question

is there a command (gcloud) that return the latest fully qualified name of an image from Artifact registry

Answer 1

Try:
PROJECT=
REGION=
REPO=
IMAGE=
gcloud artifacts docker images list \
${REGION}-docker.pkg.dev/${PROJECT}/${REPO} \
--filter="package=${REGION}-docker.pkg.dev/${PROJECT}/${REPO}/${IMAGE}" \
--sort-by="~UPDATE_TIME" \
--limit=1 \
--format="value(format("{0}#{1}",package,version))"
Because:
Filters the list for a specific image
Sorts the results descending (~) by UPDATE_TIME1
Only takes 1 value i.e. the most recent
Outputs the results as {package}#{version}
1 -- Curiously, --sort-by uses the output (!) field name not the underlying type (surfaced by e.g. --format=json or --format=yaml) name.

Answer 2

Many thanks to the previous answer, I use it to remove the tag "latest" of my last pushed artifact. I then add it when I push another. Leaving here if anyone interested.
Doc : https://cloud.google.com/artifact-registry/docs/docker/manage-images#tag
Remove tag :
gcloud artifacts docker tags delete \
$(gcloud artifacts docker images list ${REGION}-docker.pkg.dev/\
${PROJECT}/${REPO}/${IMAGE}/\
--filter="package=${REGION}-docker.pkg.dev/${PROJECT}/${REPO}/${IMAGE}"\
--sort-by="~UPDATE_TIME" --limit=1 --format="value(format("{0}",package))"):latest
Add tag:
gcloud artifacts docker tags add \
$(gcloud artifacts docker images list \
${REGION}-docker.pkg.dev/${PROJECT}/${REPO}/${IMAGE}/ \
--filter="package=${REGION}-docker.pkg.dev/${PROJECT}/${REPO}/${IMAGE}" \
--sort-by="~UPDATE_TIME" --limit=1 \
--format="value(format("{0}#{1}",package,version))") \
$(gcloud artifacts docker images list \
${REGION}-docker.pkg.dev/${PROJECT}/${REPO}/${IMAGE}/ \
--filter="package=${REGION}-docker.pkg.dev/${PROJECT}/${REPO}/${IMAGE}" \
--sort-by="~UPDATE_TIME" --limit=1 \
--format="value(format("{0}",package))"):latest
