Some configurations are required in your AWS account for this sample to work. Basically, an _S3 bucket_ (by default `spring-cloud-aws-sample` is used, but it can be changed using `cloud.aws.s3.bucket` property), and an _RDS MySQL instance_ open to the world. Additionally, we need an _IAM user_ with access key and programmatic access to AWS API so that we can access AWS resources from our development machine.

### To run locally
52+

**Note**: I was unable to run new versions of spring-cloud-aws locally. It seems it tries always to perform some autoconfiguration assuming it is deployed on AWS, and as long as it doesn't find a valid instance id, it raises an exception and stops. What follows here is the approach that worked for version 0.0.1 of the tutorial, useless in version 0.1.0. If you have an idea of how this can be solved, please fill in an issue and I'll look into it.

### To run on EC2
66+
67+
#### Create an IAM role
68+
69+
Create an IAM role with the following properties:
70+
71+
* EC2 role (i.e., a role to be attached to EC2 instances)
72+
* Policies:
73+
** AmazonS3FullAccess
74+
** AmazonRDSFullAccess
75+
76+
#### Create an EC2 instance
77+
78+
It has been tested with an instance with the following properties:
79+
80+
* AMI: Ubuntu 18.04
81+
* Type: t2.micro
82+
* Storage: 20Gb
83+
* Security group: choose or create one with ports 22 and 8080 opened
84+
* Attach the IAM role created previously
85+
86+
Once the instance has been started, ssh'd into the machine and issue the following commands:
87+
88+
```
89+
sudo apt-get update
90+
sudo apt-get install openjdk-8-jre-headless
91+
```
92+
93+
Then from your own machine, build the jar file and upload it to your EC2 instance:
94+
95+
```
96+
mvn package -DskipTests
97+
scp -i <your key> spring-cloud-aws-sample-0.1.0.jar ubuntu@<your ec2 ip>:/home/ubuntu/

### On an EC2 instance

If your EC2 instance has the appropriate role (see prerequisites above), and the jar file has been uploaded, the it can be run just by issuing:
115+
116+
java -jar spring-cloud-aws-sample-0.1.0-SNAPSHOT.jar --cloud.aws.rds.db-instance-identifier="springaws" --cloud.aws.rds.springaws.password="your rds password"
