Over the last two weeks I've talked about service discovery for container-native applications, provided a tool (Containerbuddy) to make this happen for existing applications, given an example of dynamically updating web server virtualhost configurations, and shown how to update external DNS based on container changes. Today we're going to put all these pieces together into a multi-tier application that can serve as a blueprint for a microservices architecture.
Creating an account with Joyent
In a container-native project, we need to balance the desire for ephemeral infrastructure with the requirement to provide a predictable load-balanced interface with the outside world. By updating DNS records for a domain based on changes in the discovery service, we can make sure our users can reach the load-balancer for our project at all times.
Container-native applications have new responsibilities for discovery. But no one wants to rewrite all our current applications! So what do we do about it?
Containerbuddy simplifies service discovery in Docker and provides a workaround for applications not designed from the start for container-native discovery. Here I demonstrate how to make Nginx container-native with Containerbuddy.
Common patterns for microservice container deployments carry hidden assumptions that increase operational costs and put availability at risk. Let's break down the reasons why and how to build discovery for a container-native world.

In the same way that Docker has proven to be an outstanding way to package applications from development to deploy, Mesos is becoming the de facto standard for scheduling those Dockerized applications.
Here come the hacks! Join us for the first ever MesosCon Europe Hackathon
Properly securing containers for multi-tenant bare metal is essential to eliminating VMs and achieving the promise of containerization.
VMs have long defined "cloud infrastructure," but they're hobbling our container future.
Joyent is proud to sponsor the first ever MesosCon Europe hackathon on Friday, October 9th.
If you know the version of your software artifact, but don’t have certainty about the underlying platform in which it is running, do you really have any certainty about your application?
One of the exciting challenges of being an all open source company is figuring out how to get design conversations out of the lunch time discussion and the private IRC/Jabber/Slack channels and into the broader community.
We would like to share the details of what happened during the July 27 Manta service outage, including what we have learned and what actions we are taking to prevent this from happening again.
