One of the interesting properties of #container registries is that they're essentially just big file stores.

This means you can use them to store and retrieve pretty much anything.

One idea is, if for example you need a specific binary on a host, you can just pull it from any container image, as long as you know the file location.

so this command

crane export raesene/alpine-containertools - | tar -Oxf - usr/local/bin/kubectl > kubectl

pulls the kubectl binary from the raesene/alpine-containertools image on #Docker Hub using crane.
