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" \

The following documents a trial of using etcd, and confd to automatically configure a haproxy load balancer.

It is built using a combination of blogs, resources and experimentation, but provides a rough template of the approach that would allow a fully featured balancer to be configured from etcd keyvalues.

TODO

Include systemd sidekick unit to automatically register the key's into ETCD based on a docker service (for example) being started
A more complete haproxy template that builds a valid, complex haproxy that would be capable of dealing with Future PLC's balancer requirements
