In this article, we’ll cover step-by-step how to setup and deploy a High-availability Wordpress cluster based on Docker Swarm and Amazon’s Elastic Filesystem (EFS).

By following these simple steps, you’ll have a clean install of Wordpress running on Docker Swarm:

  • Mount EFS globally
  • Create RDS database
  • Deploy Wordpress
  • Scaling Wordpress

Wordpress is by far the most popular CMS on the planet, with roughly 60% market share as of the time of this writing.

As Wordpress users ourselves, and after sifting through many incomplete or outdated guides on the subject, we decided to share a DIY-approach to replicate…

In this article, you’ll find several CloudFormation templates. They will help you set up and deploy a High-Availability Docker stack so you can easily install Docker Swarm on AWS. You can have a Docker-ready environment in minutes by launching each stack in the order below. Satisfying DevOps best practices means repeatable infrastructure and application deployments. The templates contained here are very similar to what you get when using Caylent — give it a try, it’s free.

You can deploy each CloudFormation stack by clicking the ‘Launch Stack’ button underneath the description. They are intended to be used collectively. …

In six steps, you’ll have a cluster up and running:

  • Assign 3 managers for the Docker Swarm
  • Add two nodes or ‘workers’ to the Swarm
  • Discover how to view your Swarm status
  • Run a test service across all machines

Anybody that is already familiar with Docker knows the limitations of running standalone containers in production. Containers are ephemeral and without proper scheduling and orchestration they may fail or stop running. Docker Swarm solves many of these challenges by introducing powerful container orchestration that allows services to be scheduled across multiple hosts. …

Running Containers on Windows

In a major announcement, Microsoft is bringing Linux kernels to Windows so that Linux-based containers can now run inside the Windows Server. This is accomplished through collaboration between Docker and Microsoft as a means of providing a Linux subsystem that runs atop Hyper-V Hypervisor.

This essentially means that Linux containers will now run just as easily on Windows as any other OS and can now run alongside Windows containers on the same bare metal or virtual machines. …

We recently closed the books on another amazing DockerCon conference, which took place in Austin, TX and wrapped up on April 20th. In case you were unable to attend this incredible 3-day event, we’ve decided to put together a nice little wrap up to go over the highlights, relevant news, exciting announcements and more. So, without further ado, here’s the low-down of what you missed at this year’s conference.

Astronomical Growth

The first noteworthy thing about this year’s event is how much it has grown. There were over 5,500 attendees and the number of contributors has grown from 400 to…

Preface by JP La Torre, Co-Founder & CEO at Caylent

Our API is written in Laravel, and we run it in production using Docker. So naturally one of the first tasks we had for George, our new Summer intern, was to familiarize himself with Docker to understand more about our stack. He picked it up fairly quickly, and we decided to turn his experience into what will hopefully become a new series of blog articles, aptly titled the “Intern Series”. The following article is republished from our blog.

Docker is now “the world’s leading software containerization platform”…

“What is DevOps” — A CTOs Guide

Despite surging demand for DevOps across organizations of all sizes, few seem to understand what the fuss is all about. Fewer still fully grasp its impact and how best to utilize it successfully… but we’ll come back to that in a moment.

I really like Google, not only as a search engine, but as a litmus test for what people are thinking and doing. So while doing research for this article, I turned to my old friend. A quick Google Trend search for DevOps shows just how hot this topic has gotten.
