contribute deis/registry-proxy as a replacement for kube-registry-proxy
This PR is a proposal to replace the `kube-registry-proxy` addon code with [deis/registry-proxy](https://github.com/deis/registry-proxy). We have been running this component in production for several months ([since Workflow v2.3.0](15d4c1c298/workflow-v2.3.0/tpl/deis-registry-proxy-daemon.yaml)) without any issues.
There are several benefits that this proxy provides over the current implementation:
- it's the same code that is provided in [docker/distribution's contrib dir](https://github.com/docker/distribution/tree/master/contrib/compose) which I have personally used for both Docker v1 and v2 engine deployments without any issues
- the ability to [disable old Docker clients](https://github.com/deis/registry-proxy/blob/master/rootfs/etc/nginx/conf.d/default.conf.in#L19-L23) that are incompatible with the v2 registry
- better default connection timeouts, using best practices from the Docker community as a whole
- workarounds for bugs like https://github.com/docker/docker/issues/1486 (see https://github.com/deis/registry-proxy/blob/master/rootfs/etc/nginx/conf.d/default.conf.in#L15-L16)
Things that this PR differs from the current implementation:
- it's not HAProxy.
I'm not sure how the release process goes for this component, but I bumped the version to v0.4 and changed the maintainer to myself considering this is a massive overhaul. Please let me know if this is acceptable as a replacement or if we should perhaps consider this as an alternative implementation.
Happy Friday!
Kubernetes
Introduction
Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications. Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF)
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
