The key focus areas are to determining your objective, plan out how to achieve it and know who should be involved. Set the objective – This is a critical step as it helps to set clear expectations, define a use case and outline the success criteria for exiting a POC. A common objective is to Continue reading…

How to Set Up a Registry Proxy Cache with Docker Open Source Registry

One of the latest beta features of the open source Docker v2 Registry is the ability to act as a registry proxy cache for images hosted at Docker Hub. Running a registry cache allows you to store images locally, reducing redundant image pulls across the Internet from Docker Hub. This capability is helpful for users with a large amount of Docker Engines in their environment. Instead of having each Engine pull from the Docker Hub all the time, by following this tutorial you can allow these Engines to pull from the local registry proxy cache to save time and bandwidth. Here’s how you can get started:

New Tool to Migrate From V1 Registry to Docker Trusted Registry or V2 Open Source Registry

Harder, Better, Faster, Stronger The distribution and management of Docker images are made possible by various registry services including: Docker Hub, Docker Trusted Registry and Docker Open Source Registry. Both Docker Hub and Docker Trusted Registry are commercial products that incorporate the open source registry capabilities into their respective solutions. Docker Hub is a multi-tenant service hosted by Docker while Docker Trusted Registry and open source Registry provide users with the option to host private registries behind their own firewall or dedicated cloud environment. In April of 2015, we released Docker Registry 2.0 which included a complete rewrite in Go and the new Docker Registry HTTP API v2. Upon release, Docker Registry 2.0 was put into production on Docker Hub for users of the Docker Engine 1.6 or greater making the integration of the quicker, more reliable registry was transparent Continue reading…
