jmc-hello-world

Hello World app with Amazon SQS, RDS, EBS, Worker/Webtier, Swagger, etc.

Elastic Beanstalk Configuration:

Software Configuration:

Set these environment variables:

• SERVER_PORT 5000
• SPRING_PROFILES_ACTIVE prod

DB Access:

Only necessary for "full stack" in the hello-world-rest app. Webtier connects through URL, as long as it is in the security group for RDS.

jdbc:mysql://aaxfgfb2zfv3xb.cfkkwmdp41io.us-west-2.rds.amazonaws.com:3306/hello_world

Master login: devuser/letmeinnow

• Make changes to DB instance via RDS config page: Instances > Instance Actions > Modify (Had to set 'Publicly Available' = Yes here to make it visible over Internet)
• Add my IP to the db security group
• Set the password (again) in the EBS DB configuration section

SSH Access to Instances:

• Enable the keypair in the configuration

• Add IP to security group for the instance

  jcrump@JCRUMPMAC3:~/jmc/aws$ ssh -i /Users/jcrump/jmc/aws/jcrump-adminuser.pem [email protected]

Initialize Database

Once you can use 'mysql' to log in to the DB instance, set up the schema:

% mysql -h aaxfgfb2zfv3xb.cfkkwmdp41io.us-west-2.rds.amazonaws.com -P 3306 --user=devuser --password=letmeinnow

create database hello_world;
use hello_world;create table greetings (id INT unique not null, value VARCHAR(1024));
insert into greetings (id, value) values (1, "Hello Amazon");
select * from greetings;
