Bitnami package for Express

What is Express?

Express is a minimal and unopinionated Node.js web application framework.

Overview of Express Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.

TL;DR

Local workspace
mkdir ~/myapp && cd ~/myapp
docker run --name express -v ${PWD}/my-project:/app bitnami/express:latest

Warning: This quick setup is only intended for development environments. You are encouraged to change the insecure default credentials and check out the available configuration options for the MongoDB® container for a more secure deployment.

Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
  • With Bitnami images the latest bug fixes and features are available as soon as possible.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • All our images are based on minideb -a minimalist Debian based container image that gives you a small base container image and the familiarity of a leading Linux distribution- or scratch -an explicitly empty image-.
  • All Bitnami images available in Docker Hub are signed with Notation. Check this post to know how to verify the integrity of the images.
  • Bitnami container images are released on a regular basis with the latest distribution packages available.

Looking to use Express in production? Try VMware Tanzu Application Catalog, the commercial edition of the Bitnami catalog.

Only latest stable branch maintained in the free Bitnami catalog

Starting December 10th 2024, only the latest stable branch of any container will receive updates in the free Bitnami catalog. To access up-to-date releases for all upstream-supported branches, consider upgrading to Bitnami Premium. Previous versions already released will not be deleted. They are still available to pull from DockerHub.

Please check the Bitnami Premium page in our partner Arrow Electronics for more information.

Supported tags and respective Dockerfile links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

You can see the equivalence between the different tags by taking a look at the tags-info.yaml file present in the branch folder, i.e bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml.

Introduction

Express.js, or simply Express, is a web application framework for Node.js, released as free and open-source software under the MIT License.

The Bitnami Express Development Container has been carefully engineered to provide you and your team with a highly reproducible Express development environment. We hope you find the Bitnami Express Development Container useful in your quest for world domination. Happy hacking!

Learn more about Bitnami Development Containers.

Getting started

The quickest way to get started with the Bitnami Express Development Container is using docker-compose.

Begin by creating a directory for your Express application:

mkdir ~/myapp
cd ~/myapp

Download the docker-compose.yml file in the application directory:

curl -LO https://raw.githubusercontent.com/bitnami/containers/main/bitnami/express/docker-compose.yml

Finally launch the Express application development environment using:

docker-compose up

Among other things, the above command creates a container service, named myapp, for Express development and bootstraps a new Express application in the application directory. You can use your favorite IDE for developing the application.

Note

If the application directory contained the source code of an existing Express application, the Bitnami Express Development Container would load the existing application instead of bootstrapping a new one.

After the Node application server has been launched in the myapp service, visit http://localhost:3000 in your favorite web browser and you'll be greeted by the default Express welcome page.

In addition to the Express Development Container, the docker-compose.yml file also configures a MongoDB® service to serve as the NoSQL database backend of your Express application.

Read-only environment variables

Executing commands

Commands can be launched inside the myapp Express Development Container with docker-compose using the exec command.

Note:

The exec command was added to docker-compose in release 1.7.0. Please ensure that you're using docker-compose version 1.7.0 or higher.

The general structure of the exec command is:

docker-compose exec <service> <command>

, where <service> is the name of the container service as described in the docker-compose.yml file and <command> is the command you want to launch inside the service.

Following are a few examples of launching some commonly used Express development commands inside the myapp service container.

  • Load the Node.js REPL:

    docker-compose exec myapp node
    
  • List installed NPM modules:

    docker-compose exec myapp npm ls
    
  • Install a NPM module:

    docker-compose exec myapp npm install bootstrap --save
    docker-compose restart myapp
    

Connecting to Database

Express by default does not require a database connection to work but we provide a running and configured MongoDB® service and an example file config/mongodb.js with some insights for how to connect to it.

You can use Mongoose ODM in your application to model your application data.

Going to Production

The Express Development Container generates a Dockerfile in your working directory. This can be used to create a production-ready container image consisting of your application code and its dependencies.

  1. Build your Docker image

    docker build -t myregistry/myapp:1.0.0
    
  2. Push to an image registry

    docker push myregistry/myapp:1.0.0
    
  3. Update orchestration files to reference the pushed image
