Tips for Deploying NGINX (Official Image) with Docker

In the past year alone, the Docker community has created 100,000+ images and over 300+ million images have been pulled from Docker Hub to date.  Over 20 million of these pulls came from the 70+ Official Images that Docker develops in conjunction with upstream partners, like Oracle, CentOS, and NGINX.

NGINX is used by over 40% of the world’s busiest websites and is an open-source reverse proxy server, load balancer, HTTP cache, and web server.  The official image on Docker Hub has been pulled over 3.4 million times and is maintained by the NGINX team. This post from NGINX provides a walkthrough on using the Docker Image to deploy the open-source version of NGINX.

Docker 1.6: Engine & Orchestration Updates, Registry 2.0, & Windows Client Preview

We are happy to announce updates to Docker Engine, Registry, Compose, Swarm, and Machine. We are releasing them all at the same time so you can test and roll them out together, and so that we can ship features that span multiple tools. The features in this release are designed to improve the dev experience with faster image pulls, a preview of Docker client for Windows, and support for apps beyond the dev environment in Compose.

Docker Engine 1.6

The Docker Engine has been greatly improved since 1.5, with some highly requested features in addition to Windows Client support. We could not have created such an amazing release without the help from awesome contributors. You can get started by downloading Docker Engine 1.6 and checking out the changelog here.

Now let’s check out what’s new in Docker Engine 1.6.


Faster and Better Image Distribution with Registry 2.0 and Engine 1.6

There has been incredible growth in the usage of Docker Hub: we have now served over 300 million pulls to developers around the world, and will soon be serving 100 million per month. The current generation of the Registry has done a good job so far, but we know we need a better foundation to support this growth and keep your image pulls running fast and reliably.

We’re pleased to announce a huge update to how images are distributed, which will make pulling images dramatically faster and more reliable. It’s the foundation that will support image distribution in years to come. 

Docker Engine 1.6, the Docker Hub and the self-hosted Registry now support a new API which has been completely redesigned with this type of performance and scale in mind. It features:

  • Faster image pulls: Downloading images with lots of layers is now faster.
  • New immutable image references: Images are now content addressable, so you can specify exactly what image content you want to pull and run by using a SHA digest: `docker pull myimage@sha256:0ecb2ad60` 

The Docker Hub is running this new API today, so download Docker Engine 1.6 and try it out. If you want to learn more about this API, head over to the documentation.


Docker Tutorial 5 – Basic Networking

This is a casual Docker tutorial series. We started out first with very simple sessions on how to install and use the docker run command. In future videos we will hit more advanced topics.

This fifth video talks about basic Docker Networking. We will also show some examples of port mapping with a basic Apache image (https).  Then we will show how a basic Haproxy/Wordpress/Mysql (LAMP Stack) could be configured on a Docker host.


Docker Announces $95m Series D Funding Round

This morning, we announced a $95M Series D funding round that will help ensure that Docker can deliver on an ambitious set of long term priorities. More importantly, we believe that it will enable us to deliver on product, support, and community enablement in a manner worthy of our incredible ecosystem and the sea change that the open Docker platform is bringing to how distributed applications are built, shipped, and run.



DockerCon CFP Summary

Our DockerCon 2015 call for papers closed last week, and we’d like to sincerely thank the 338 individuals who submitted talks. These submissions are further proof of a bright, witty and extremely talented community that surrounds Docker. We are very excited about the content that will be at DockerCon this year.

We have formed a community committee who will begin the review and voting process. Please keep an eye on the blog over the next couple of weeks. We will make session selection announcements here and notify all who entered by email when the results are final.
