Micro-Services demo using OpenTracing API

Prerequisites

• curl
• jq

####How to run
Fill GSCTL_VERSION in env.sh and then run bin/start-demo.sh from the bin folder

to run scemaEvoulution stage run ./start-schema-evoulution.sh

####demo flow:

1. Launch on cloud no dev ops - createCluster.sh, ./deployServices.sh
2. Provision elasticity (cluster change size, scale out)
   • java -jar gsctl.jar node list / add /remove
3. Security built in
   • manager url leads to login page, user: gs-admin, password:
4. connect gsctl cli to remoter cluster
   • Add node to cluster from another directory (using token and server url)
5. User App
   • java -jar gsctl.jar list-services
   • go to user-app service url and perform order from UI
6. Feeder (run in parallel to schema evolution to see the affects)
   • ./ordersFeeder 1000 4 1
7. Schema evolution
   • ./start-schema-evoulution.sh
   • show all staged in ops-ui (orders-space, orders-service, orders-mirror - two versions)
8. Feeder (run to fill data to see data move during scale in/out)
   • ./ordersFeeder 3096 8 0
9. Heap analysis
10. Scale up/down
    • orders-space / orders-service
11. Scale in/out
    • scale delivery-space (wait for feeder to finish before starting to scale)
12. Explain plan
    • run query ...
13. Visibility suite (grafana, ops ui, zipkin)
    • run './tracing.sh true' to turn tracing on
    • java -jar gsctl.jar list-services
    • go to user-app and perform an order from UI
    • go to zipkin url and show trace of latest order
    • go to grfana and show dashboards of spaces and services
14. Run ./destroy-cluster.sh to take demo down
