Google announces enhancements to Container Engine and Container Registry

Over the past few months, Google has made several additions and enhancements to its Cloud Platform. Google has introduced a Container Engine, for setting up container clusters and managing apps, a Container Registry, for securely storing container images, and the introduction of Kubernetes, Google’s container orchestration system. Google has recently announced new enhancements to these products.

For Google Container Registry, Google has added Docker Registry V2 API support. Users can now use V2 API to push and pull Docker images into Container Registry. This allows content addressable references, parallel layer downloads and digest-based pulls but users need to be using Docker 1.6 or above. This enhancement will give users performance enhancements with 40% faster image pulling, advanded authentication, and TwistLock integration.

Google updated Kubernetes early this week to version 1.1. Google is bringing the benefits of 1.1 over the Container Engine users allowing them to benefit from running Container Engine in a high-scale environment. Highlights include:

  • Horizontal pod autoscaling helps resolve the uneven experiences users see when workloads go through spiky periods of utilization, meaning your pods can scale up and down based on CPU usage.
  • HTTP load balancer that enables routing traffic to different Kubernetes services based on HTTP traffic, such as using different services for sub-URLs.
  • A re-architected networking system that allows native iptables and reduces tail latency by up to 80%, virtually eliminating CPU overhead and improving reliability.


These new enhancments are available now for existing Container Engine and Container Registry customers. And the new updates will be rolled out to Container Engine users over the next week.
