Geek's Movie Shop (former Stan's Robot Shop) is a sample microservice application you can use as a sandbox to test and learn containerised application orchestration and monitoring techniques. It is not intended to be a comprehensive reference example of how to write a microservices application, although you will better understand some of those concepts by playing with it. To be clear, the error handling is patchy and there is not any security built into the application.

Forked from the original Robot-Shop repository, by Instana.

This sample microservice application has been built using these technologies:

• NodeJS (Express)
• Java (Spark Java)
• Python (Flask)
• Golang
• PHP (Apache)
• MongoDB
• Redis
• MySQL
• RabbitMQ
• Nginx
• AngularJS

1. Setup an EC2 Amazon Linux instance with these properties:
   • t2.medium
   • 24Gb disk
2. Connect to the instance
3. Make a copy of setup-ec2-instance.sh and set the required variables:
   • YOUR_NAME
   • YOUR_COMPANY_NAME
   • NEW_RELIC_LICENSE_KEY
4. Copy and paste the changed content on the EC2 terminal
5. Open port 8888 on EC2 instance to the world (tip: edit instance security group inbound rules)
6. Take a note of the instance hostname (we need this value to set the PUBLIC_URL variable in .env)

1. Make a copy of setup-repository.sh and set the required variables:

   • GITHUB_USER
   • GITHUB_USER_NAME
   • GITHUB_USER_EMAIL
   • GITHUB_REPO

2. Copy and paste the changed content on the EC2 terminal

3. Edit .env and set the required variables:

   • GITHUB_USER
   • GITHUB_USER_NAME
   • GITHUB_USER_EMAIL
   • GITHUB_REPO
   • DOCKERHUB_USER
   • TAG=latest
   • PUBLIC_URL=http://YOUR_INSTANCE_HOSTNAME:8888
   • NEW_RELIC_LICENSE_KEY
   • CLUSTER_NAME=local
   • NEW_RELIC_BROWSER_LICENSE_KEY
   • NEW_RELIC_BROWSER_APPLICATION_ID

4. Change the repository to the desired training step

   git branch -a

   git checkout --track <branch name>

   Example:

   git checkout --track origin/S00-no-instrumentation

1. Build all services

   docker-compose build

2. Bring all services up

   docker-compose up -d

3. Check loader service

   docker container ls

   Take note of the loader container id and use below

   docker logs <container id> -f

   Output should show a sequence of API calls across all services. Double-check PUBLIC_URL in .env if there is any error output.

The store front is available on http://EC2_INSTANCE_PUBLIC_DNS:8888

docker-compose down

1. Run setup-eks-cluster.sh from the repository folder (it might take 15 mins to complete)

   cd ~/${GITHUB_REPO}

   ./setup-eks-cluster.sh

2. Install New Relic Agents

   cd ~/${GITHUB_REPO}/_infra

   ./k8-newrelic.sh -c

3. Deploy services

   docker login

   cd ~/${GITHUB_REPO}

   docker-compose push

   cd ~/${GITHUB_REPO}/_infra

   ./k8-services.sh -c

4. Take note of EKS Load Balancer public URL

   kubectl get services

5. Update .env PUBLIC_URL variable with this DNS name on port 8080

6. Deploy the loader

   ./k8-loader.sh -c
