Hi,

We run Sonatype Nexus 3 to cache various dependencies. As Docker hub doesn't always have the latest Elastic images (for example, at the time of writing not all 6.5 images are available), I'd like to proxy [docker.elastic.co](http://docker.elastic.co)

However this does not appear to work and I get 500 errors ("authentication required") when I try to run a search via the proxy. Yet if I try to pull using the proxy, it all works fine.

Has anyone managed to get Sonatype Nexus 3 full working with [docker.elastic.co](http://docker.elastic.co)?

I did see [this post](https://discuss.elastic.co/t/docker-proxy-cache-registry-for-docker-elastic-co/100283), but is seems like a bit of a cludge to me.
