Configuration files for deploying RSS Recipes on Kubernetes.

System requirements

• A Kubernetes cluster
  • minikube on a local machine or
  • Physical/virtual cluster

How to deploy RSS Recipes

RSS Recipes can be deployed by executing the following steps on the master node:

1. Deploy ActiveMQ server
   • kubectl create -f https://raw.githubusercontent.com/hora-prediction/kubernetes-recipes-rss/master/activemq.yaml
2. Deploy Kieker Logging Server
   • kubectl create -f https://raw.githubusercontent.com/hora-prediction/kubernetes-recipes-rss/master/kls.yaml
3. Deploy RSS Recipes application
   • kubectl create -f https://raw.githubusercontent.com/hora-prediction/kubernetes-recipes-rss/master/rssreader.yaml for the application without instrumentation or
   • kubectl create -f https://raw.githubusercontent.com/hora-prediction/kubernetes-recipes-rss/master/rssreader-kieker.yaml for the application instrumented with Kieker
4. Initialize cassandra keyspace
   • curl -s https://raw.githubusercontent.com/hora-prediction/kubernetes-recipes-rss/master/initialize-cassandra.cql -o initialize-cassandra.cql
   • kubectl cp initialize-cassandra.cql $(kubectl get po | grep ^cassandra- | head -n 1 | cut -d ' ' -f1):/.
   • kubectl exec $(kubectl get po | grep ^cassandra- | head -n 1 | cut -d ' ' -f1) -- cqlsh -f /initialize-cassandra.cql $(kubectl get nodes | head -n 2 | tail -n 1 | cut -d ' ' -f1) 31002 Note: This step may need to be executed many times until it returns success.
5. Deploy Locust for load testing
   • kubectl create -f https://raw.githubusercontent.com/hora-prediction/kubernetes-recipes-rss/master/locust-master.yaml
   • kubectl create -f https://raw.githubusercontent.com/hora-prediction/kubernetes-recipes-rss/master/locust-worker.yaml

After deploying all components, the following web-ui can be accessed:

• For minikube
  • RSS Recipes
    • http://192.168.99.100:31000/jsp/rss.jsp
  • Locust
    • http://192.168.99.100:31050
  • ActiveMQ
    • http://192.168.99.100:31010 (username: admin, password: admin)
  • Kieker monitoring log (available as a zip file)
    • http://192.168.99.100:31020/logs
• For physical/virtual cluster
  • Same as those for minikube but replace 192.168.99.100 with one of the node IPs. (Run kubectl get nodes to see the list of nodes)
