Docker 1.11: The first runtime built on containerd and based on OCI technology

We are excited to introduce Docker Engine 1.11, our first release built on runC ™ and containerd ™. With this release, Docker is the first to ship a runtime based on OCI technology, demonstrating the progress the team has made since donating our industry-standard container format and runtime under the Linux Foundation in June of 2015. Over the last year, Docker has helped advance the work of the OCI to make it more readily available to more users. It started in December 2015, when we introduced containerd ™, a daemon to control runC. This was part of our effort to break out Docker into small reusable components. With this release, Docker Engine is now built on containerd, so everyone who is using Docker is now using OCI. We’re proud of the progress we’ve made on the OCI with the 40+ members to continue the work to standardize container 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:

Get Docker on Demand for Amazon Web Services

Docker Trusted Registry, Docker Engine and Business Day Support available for a free 30 day trial to build, ship and run distributed applications in Amazon Web Services. Amazon Web Services (AWS) is a popular place for companies of all sizes to run their test farms and production clusters. Many of the world’s most popular websites like Yelp, Gilt and Spotify run at scale on AWS using Docker.   We started simplifying the developer workflow earlier this year with an AWS driver for Docker Machine to automate the provisioning of AWS instances and deploying Docker Engine with the single command ‘machine create’. At DockerCon, we added Docker Trusted Registry AMI on the AWS Marketplace to allow development teams to store, manage and collaborate on their Docker images with a registry service deployable in your AWS VPC, and today we take that Continue reading…

Announcing Docker 1.8: Content Trust, Toolbox, and Updates to Registry and Orchestration

We’re thrilled to announce Docker 1.8 with support for image signing, a new installer, as well as incremental improvements to Engine, Compose, Swarm, Machine and Registry. You’ve been telling us that you want Docker to be more extensible and composed of smaller, standalone components. We hear you loud and clear. In June, we announced our intention to release runC as a separate piece of plumbing. With this release we’re taking another step towards that goal. The system powering image signing has been implemented as a separate piece of plumbing called Notary, and volume plugins, an experimental feature in 1.7, has now been promoted to the stable release. Across the board we’ve been making the usual quality improvements – something we know is important to all of you running Docker in production.

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…
