The previous article described several ways to implement Continuous Deployment. Specifically, it described, among other things, how to implement it using Docker to deploy applications as containers and nginx for reverse proxy necessary for successful utilization of blue-green deployment technique. All that was running on top of CoreOS, operating system specifically designed for running Docker containers.
In this article we'll try to do the same process using Ansible (an open-source platform for configuring and managing computers). Instead of CoreOS, we'll be using Ubuntu.
The previous article described several Continuous Deployment strategies. In this one we will attempt to provide one possible solution for reliable, fast and automatic continuous deployment with ability to test new releases before they become available to general users. If something goes wrong we should be able to rollback back easily. On top of that, we'll try to accomplish zero-downtime. No matter how many times we deploy our applications, there should never be a single moment when they are not operational. Continue reading →
Previous article provided introduction to continuous deployment. In this one we'll continue where we left and explore different strategies to deploy software. The article is in no way an exhaustive list of ways to deploy applications but tries to provide few common ways that are in use today. Continue reading →
