This repository contains the showcase for my talk at O'Reilly Architecture Conference NY 2018. For details see: https://conferences.oreilly.com/software-architecture/sa-ny/public/schedule/detail/63967

The slides for this talk can be found on SpeakerDeck here: https://speakerdeck.com/lreimer/data-services-processing-big-data-the-microservice-way

The individual data services are all separate Gradle builds. Make sure to build these individually.

$ cd hazelcast/
$ ./gradlew clean build

$ docker-compose up --build

• Install the gcloud SDK for Mac (or Windows)
• Make sure you have a project with billing activated as well as the container engine management API
• Make sure you have kubectl installed, either using gcloud or using brew et.al.

$ gcloud config list project
$ gcloud config set compute/zone europe-west1-b
$ gcloud config set container/use_client_certificate False

$ gcloud container clusters create data-services --num-nodes=5 --enable-autoscaling --min-nodes=5 --max-nodes=7

$ gcloud container clusters describe data-services

$ gcloud auth application-default login
$ kubectl cluster-info

Once you are done, remember to delete the cluster again!

$ gcloud container clusters delete data-services

• Rabbit MQ
  • URL: http://localhost:15672
  • User: guest
  • PWD: guest
• Active MQ
  • URL: http://localhost:8161
  • User: admin
  • PWD: admin
• Cockroach DB
  • URL: http://localhost:8080
  • User: root
  • PWD: root

Follow the instructions here: https://www.cockroachlabs.com/docs/stable/orchestrate-cockroachdb-with-kubernetes-insecure.html

Also, I have included the YAML files in kubernetes/infrastructure/. First apply the deployment. Once everything has started, run the init job and finally create the services.

Test the cluster:

$ kubectl run cockroachdb -it --image=cockroachdb/cockroach --rm --restart=Never -- sql --insecure --host=cockroachdb-public

To test the different REST endpoints use the Postman collection: data-services.postman_collection.json
