skopeo

skopeo: Work with remote images registries - retrieving information, images, signing content

configure container registry

it uses the docker hub by default when you just use docker://, otherwise specify the path like so: docker://quay.io/

list docker hub image tags

life is too short to try and find anything on the docker hub website when it comes to image tags…

skopeo list-tags docker://grafana/loki
skopeo list-tags docker://devlikeapro/waha | jq -r '.Tags[]'
skopeo list-tags docker://ghcr.io/org/image | jq -r '.Tags[]'

inspect images

when run from macos, it might be easier to just override the OS if you want to get some specific information:

skopeo inspect --override-os linux docker://grafana/loki
