RobotShop on PCF [WIP]

Requirements

The following tiles up and running in the PCF foundation:

• Pivotal Application Service
• RabbitMQ for PCF
• Redis for PCF
• MySQL for PCF
• MongoDB Enterprise Service for PCF
• Instana Microservices Application Monitoring for PCF

Create an organization and a space

cf create-org stan
cf create-space -o stan robotshop

Ensure routes are available

The following routes must be available for use:

• web.<domain>
• ratings.<domain>
• cart.<domain>
• catalogue.<domain>
• shipping.<domain>
• user.<domain>
• payment.<domain>
• dispatch.<domain>

Set up the services

cf target -o stan -s robotshop

First app push

RobotShop relies on specific binding names between services and apps, so we first push the apps without creating instances (all instance counts in the manifest are 0).

From the root of the repo:

cf push -f CF/manifest.yml

Bind the services

Now that we have both apps and services, we can bind the former to the latter:

cf cs p.mysql db-small mysql-cities
cf cs p.mysql db-small mysql-ratings
cf cs mongodb-odb replica_set_small mongodb
cf cs p.redis cache-small redis
cf cs p.rabbitmq single-node-3.7 rabbitmq

Init MongoDB

cf run-task mongo-init 'node init-db.js' --name "Init MongoDB"

Init MySQL databases

Ratings database

cf bind-service mysql-init mysql-ratings --binding-name ratings_database
cf run-task mysql-init 'node init-db.js init-ratings.sql ratings_database' --name "Init Ratings database"

Shipping database

This one is not automated yet, as the mysql-init task app chokes on the large SQL init file. Something that works is to:

1. bosh ssh into the MySQL virtual machine
2. Find out admin password from /var/vcap/jobs/mysql/config/mylogin.cnf
3. Download the "cities" init sql file and gunzip it
4. /var/vcap/packages/percona-server/bin/mysql -u admin -p<adminpwd> -P 3306 -D service_instance_db < <sql_file>

Configure EUM

Create a website in Instana. Edit the web/static/eum.html file accordingly, specifically replacing the values of the reportingUrl and key ienums.

Spin up the containers

Note: Feel free to replace the value after -i with how many container of any one kind you want.

cf scale -i 1 web
cf scale -i 1 ratings
cf scale -i 1 cart
cf scale -i 1 catalogue
cf scale -i 1 shipping
cf scale -i 1 user
cf scale -i 1 payment
cf scale -i 1 dispatch
