## TL;DR

### Local workspace

```console
$ mkdir ~/myapp && cd ~/myapp
$ curl -LO https://raw.githubusercontent.com/bitnami/bitnami-docker-express/master/docker-compose.yml
$ docker-compose up
```

**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](https://github.com/bitnami/bitnami-docker-mongodb#readme) 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](https://github.com/bitnami/minideb) a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
* All Bitnami images available in Docker Hub are signed with [Docker Content Trust (DCT)](https://docs.docker.com/engine/security/trust/content_trust/). You can use `DOCKER_CONTENT_TRUST=1` to verify the integrity of the images.
* Bitnami container images are released daily with the latest distribution packages available.

## Introduction

[Express.js](http://expressjs.org/), or simply Express, is a web application framework for [Node.js](https://nodejs.org), released as free and open-source software under the [MIT License](https://github.com/nodejs/node/blob/master/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.](https://docs.bitnami.com/containers/how-to/use-bitnami-development-containers/)

## Getting started

The quickest way to get started with the Bitnami Express Development Container is using [docker-compose](https://docs.docker.com/compose/).

Begin by creating a directory for your Express application:

```console
mkdir ~/myapp
cd ~/myapp
```

Download the [docker-compose.yml](https://raw.githubusercontent.com/bitnami/bitnami-docker-express/master/docker-compose.yml) file in the application directory:

```console
$ curl -LO https://raw.githubusercontent.com/bitnami/bitnami-docker-express/master/docker-compose.yml
```

Finally launch the Express application development environment using:

```console
$ 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](https://raw.githubusercontent.com/bitnami/bitnami-docker-express/master/docker-compose.yml) file also configures a MongoDB® service to serve as the NoSQL database backend of your Express application.

## Executing commands

Commands can be launched inside the `myapp` Express Development Container with `docker-compose` using the [exec](https://docs.docker.com/compose/reference/exec/) command.

> **Note**:
>
> The `exec` command was added to `docker-compose` in release [1.7.0](https://github.com/docker/compose/blob/master/CHANGELOG.md#170-2016-04-13). Please ensure that you're using `docker-compose` version `1.7.0` or higher.

The general structure of the `exec` command is:

```console
$ 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:

  ```console
  $ docker-compose exec myapp node
  ```

- List installed NPM modules:

  ```console
  $ docker-compose exec myapp npm ls
  ```

- Install a NPM module:

  ```console
  $ 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&reg; service and an example file `config/mongodb.js` with some insights for how to connect to it.

You can use [Mongoose](http://mongoosejs.com/) 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

  ```console
  $ docker build -t myregistry/myapp:1.0.0
  ```

2. Push to an image registry

  ```console
  $ docker push myregistry/myapp:1.0.0
  ```

3. Update orchestration files to reference the pushed image

## Issues

If you encountered a problem running this container, you can file an [issue](https://github.com/bitnami/bitnami-docker-express/issues/new). For us to provide better support, be sure to include the following information in your issue:
