Three Considerations for Planning your Docker Datacenter Deployment

Congratulations! You’ve decided to make the change your application environment with Docker Datacenter. You’re now on your way to greater agility, portability and control within your environment. But what do you need to get started? In this blog, we will cover things you need to consider (strategy, infrastructure, migration) to ensure a smooth POC and migration to production. 1. Strategy Strategy involves doing a little work up-front to get everyone on the same page. This stage is critical to align expectations and set clear success criteria for exiting the project. 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…

Get to Know the Docker Datacenter Networking Updates

The latest release of Docker Datacenter (DDC) on Docker Engine 1.12 brings many new networking features that were designed with service discovery and high availability in mind. As organizations continue their journey towards modernizing legacy apps and microservices architectures, these new features were created to address modern day infrastructure demands. DDC builds on and extends the built-in orchestration capabilities including declarative services, scheduling, networking and security features of Engine 1.12. In addition to these new features, we published a new Reference Architecture to help guide you in designing and implementing this for your unique application requirements. Among the new features in DDC are: DNS for service discovery Automatic internal service load balancing Cluster-wide transport-layer (L4) load balancing Cluster-wide application-layer (L7) load balancing using the new HTTP Routing Mesh (HRM) experimental feature   When creating a microservice architecture where services are often Continue reading…

Introducing Image Signing Policy in Docker Datacenter

My colleague Ying Li and I recently blogged about Securing the Software Supply Chain and drew the analogy between traditional physical supply chains and the creation, building, and deployment involved in a software supply chain. We believe that a software pipeline that can be verified at every stage is an important step in raising the security bar for all software, and we didn’t stop at simply presenting the idea. Integrated Content Trust and Image Signing Policy In the recent release of Docker Datacenter,  we announced a new feature that starts to brings these security capabilities together along the software supply chain. Built on Notary, a signing infrastructure based on The Update Framework (TUF), along with Docker Content Trust (DCT), an integration of the Notary toolchain into the Docker client, DDC now allows administrators to set up signing policies that prevent untrusted content Continue reading…

5 Tales from the Docker Crypt

(Cue the Halloween music) Welcome to my crypt. This is the Docker crypt keeper speaking and I’ll be your spirit guide on your journey through the dangerous and frightening world of IT applications. Today you will learn about 5 spooky application stories covering everything from cobweb covered legacy processes to shattered CI/CD pipelines. As these stories unfold, you will hear  how Docker helped banish cost, complexity and chaos. Tale 1 – “Demo Demons” Splunk was on a mission to enable their employees and partners across the globe to deliver demos of their software regardless of where they’re located in the world, and have each demo function consistently. These business critical demos include everything from Splunk security, to web analytics and IT service intelligence. This vision proved to be quite complex to execute. At times their SEs would be in customer meetings, but Continue reading…

How To Dockerize Vendor Apps like Confluence

Docker Datacenter customer, Shawn Bower of Cornell University recently shared their experiences in containerizing Confluence as being the start of their Docker journey. Through that project they were able to demonstrate a 10X savings in application maintenance, reduce the time to build a disaster recovery plan from days to 30 minutes and improve the security profile of their Confluence deployment. This change allowed the Cloudification team that Shawn leads to start spending the majority of their time helping Cornelians to use technology to be innovative. Since the original blog was posted, there’s been a lot of requests to get the pragmatic info on how Cornell actually did this project.  In the post below, Shawn provides detailed instructions on how Confluence is containerized and how the Docker workflow is integrated with Puppet. Written by Shawn Bower As we started our Journey to move Continue reading…

The 10 Most Common Questions IT Admins ask About Docker

Over the past few months we have attended a string of industry tradeshow events, helping to teach the world about Docker for enterprise. We were at HPE Discover, DockerCon, RedHat Summit and Cisco Live all within the past 6weeks! I had the pleasure of helping to represent Docker at each events and spoke with attendees. Some folks worked in IT ops, while others worked in development. I also spoke with a lot of folks working as IT admins within their company’s infrastructure team, and over time, I began to notice some trends when it came to the types of questions they asked. This got me thinking. Why not put together a list of the most common questions from IT administrators? I mean there’s a good chance there are other IT infrastructure folks out there who have the very same questions, Continue reading…
