Have you ever felt the pain that comes when your app runs fine on development, but breaks terribly in production? Maybe your CI build has been red for days, but you haven't had time to figure out how the CI server is misconfigured?
With containers, you can easily rid yourself of such dependency woes. If the app runs in a container on one machine, it will most likely run in the same container on another.
Once you've bought into a container-based development workflow, the question soon arises: how can I get my production server to run my application in a container without the difficulty of having to provision a bare server with all of the other services, writing deploy tasks, and handling scaling issues on my own? In short, can I have a managed production environment that also supports containers?
The answer is yes. Using Deis, an open source Platform as a Service, you can host and manage your Docker-based application using your own Amazon Web Services (AWS) servers, without the hassle of configuring a bare Linux server.
I recently deployed a simple Rails app to Deis, and took notes along the way. In this post, I'll share the steps I took to set up a Deis Pro account and deploy a new application.Read More
