Show HN: ttl.sh – Anonymous, ephemeral (& free) Docker image registry

We built this tool for use in some of our CI workflows. It solves the problem of not having to share secrets to a Docker registry for pull requests. It is a pretty simple service (and OSS) if you want to run it yourself: https://github.com/replicatedhq/ttl.sh (we'll be contributing a Kubernetes manifest soon to make it easier to deploy your own private instance).
