One liner for deleting images from a v2 docker registry

Just plug in your own values for registry and repo/image name.

registry='localhost:5000'
name='my-image'
curl -v -sSL -X DELETE "http://${registry}/v2/${name}/manifests/$(
    curl -sSL -I \
        -H "Accept: application/vnd.docker.distribution.manifest.v2+json" \

set_system_clock_from_google.sh

Sets system time based on what is reported by google.com. Useful for cases where it is not possible to use the standard ntpdate command. For eample, if a Linux machine is on a network which is only able to reach the internet through an HTTP proxy.

Inspired by ryenus' answer @ https://superuser.com/a/807326/72342
