Deploying a NodeJS App (in combination with Zeit, Docker, CircleCI and Heroku/Amazon AWS)

Install example app locally

npm install

How to test example App locally

npm run start

Then navigate to http://localhost:80/

How to deploy example App to a Local Docker Machine

docker build -t case-docker-api .
docker run -p 80:80 case-docker-api

You should see something like this:

> npm info it worked if it ends with ok
> npm info using npm@3.10.10
> npm info using node@v7.3.0
> npm info lifecycle case-docker-api@0.1.0~prestart: case-docker-api@0.1.0
> npm info lifecycle case-docker-api@0.1.0~start: case-docker-api@0.1.0
> case-docker-api@0.1.0 start /usr/src/app
> node ./server/server
> Example app listening on port 80!

How to test this example app in Docker using different environment settings

You can use docker compose to accomplish this. In the project there are 2 docker compose files. One for dev and the other one for a production environment.

First create a docker image.

docker-compose build

Then start the app

For development

docker-compose -f docker-compose.yml up

or production

docker-compose -f docker-compose.production.yml up

As an example you will see there is a different environment setting for a database connection string in this project. This can be useful if you want to test the docker image on your local docker machine using a development database or rather connect to production database (or maybe another database..)
