Why use Dokkuĭokku provides a nice balance between cost (Dokku itself is open-source and free), features and control. We're going to see both of these approaches to working with Dokku in this article. If the buildpacks don't cater to your needs, you can customize the build process by providing your own Dockerfile, and Dokku will use that instead. When you push an application, it builds the app using the official Heroku Buildpacks, and so if your app already works on Heroku, it's probably going to work here. It will also automatically configure Nginx so that your application can be reached, with its virtual hostname support. In essence, it allows you as a developer to push applications to it using Git where it will build those applications for you, package them into a Docker container, and then manage the lifetime of that container on your behalf. They also have complete documentation available online. They have a variety of ways you can get in touch if you need help, including IRC and Slack. Dokku supports Ubuntu 14.04/16.04, Debian 8.2 and CentOS 7 platforms, and has a very small team of core maintainers. It uses Docker under the hood to create and run applications inside containers.

"Learn how to easily set up a Dokku server and deploy applications to it using Git"ĭokku - The smallest PaaS implementation you've ever seen - is a piece of open-source software that "helps you build and manage the lifecycle of applications". We're going to be using it in conjunction with Dokku to package up a Vue.js application and run it on a remote server.Īs the process of deploying applications to a Dokku server revolves around Git, make sure you have Git installed on your system before you start. Docker is a container platform that allows us to package up applications and services, distribute them and run them in a consistent environment.

You should also install Docker for Developers for your operating system.
If you would like to follow along, you should have the latest version of Node installed. However, installing Node and Docker is highly recommended as we're going to be doing some local testing before deployment to make sure that everything is working as it should. As long as you have cloned the sample application, you can perform most of the steps in this tutorial. You do not strictly need any software other than Git and a text editor to follow along with this article, as most of the work is done on the Dokku server. We'll also be looking at how to optimize the deployment using Docker. TL DR: In this article, we're going to be creating a couple of very simple Node applications and hosting them on a DigitalOcean droplet using Dokku, an open-source PaaS.
