Netflix OSS on Heroku Demo: Eureka Server

This project demonstrates the use of Netflix OSS with Spring Cloud on Heroku. It defines a Eureka server that can be used for service discovery. Once this project is up and running, you can connect the Eureka client demo to it.

Quickstart

Once it's deployed, Eureka will prompt you for credentials. The defaults are user and password.

Production Deployment

First, create a Heroku account and then download and install the Heroku toolbelt.

Now clone this project and move into it's root directory.

$ git clone git@github.com:kissaten/heroku-eureka-server-demo.git
$ cd heroku-eureka-demo/

Then create a Heroku application by running this command:

$ heroku create
Creating fast-beach-5250... done, stack is cedar-14
https://fast-beach-5250.herokuapp.com/ | https://git.heroku.com/fast-beach-5250.git
Git remote heroku added
```

Now create a configuration variable to set the default user's
password. Run this command, but substitute a unique password for `<PASSWORD>`:

```
$ heroku config:set EUREKA_USER_PASSWORD=<PASSWORD>
```

You're ready to deploy. There are two methods you can choose from: Git deployment and
Maven deployment. The former compiles the application remotely, while the latter
uses locally compiled artifacts and pushes them to Heroku.

### Deploying with Git

With you're application prepared (as describe above), simply run this command to
deploy via Git:

```sh-session
$ git push heroku master
```

Your code will be pushed to the remote Git repository, and the Maven process
will execute on the Heroku servers.

### Deploying with Maven

With you're application prepared, simply run this command to
deploy (but replace `<appname>`  with the name of the Heroku application you created):

```sh-session
$ mvn -Dheroku.appName=<appname> heroku:deploy
...

## Viewing Your Application

When your chosen deployment method is finished, run this command to view
your application:

```
$ heroku open
```

The browser will prompt you for credentials. Enter "user" for the username,
and the unique password you set as a configuration variable.
