#DOCKERIZE NODEJS POSTGRES APP HOW TO#
The source code for th is application can be found on GitHub.Īlthough simple, the sample application demonstrates how to build a Docker image hosting a Node.js application and some of the inefficiencies that a naive approach to building Docker images can lead to.
#DOCKERIZE NODEJS POSTGRES APP GENERATOR#
It is simply the end result of running the Express application generator to generate a web page displaying “Welcome to Express.” The sample application we’ll build in this post is extremely rudimentary. In this post, we’ll look at how a Docker image can host a simple Node.js application, review some common pitfalls you may run into, and explore how Buildpacks allow you to efficiently create Docker images, often with no additional configuration. By capturing these best practices, Buildpacks ensure your Docker image builds are quick and efficient. It is very easy to unnecessarily download thousands of packages each time an image is built, wasting time, consuming bandwidth, and costing money.Ĭloud Native Buildpacks emerged as a convenient way to build Docker images by leveraging the decade of experience large hosting providers have from generating and hosting Docker images. However, creating a Docker image from your custom application code requires a little expertise, especially if you regularly rebuild images as you make changes to your code. Dockerize Node.js apps with Buildpacksĭocker has long been the go-to tool to create easily distributable and deployable artifacts.Ī Docker image can host code written in almost any language every major operating system supports the ability to execute Docker images and all the cloud providers have at least one platform that allows deployed Docker images. By night I'm playing with bleeding edge open source projects and contributing to various blogs. By day you'll find me integrating enterprise platforms with Octopus, writing guides and books for platforms like Kubernetes, blogging, and training my colleagues.
