Sample Cloud App with Continous Integration, Continous Deployment and Continous Monitoring

1 Build the Tomcat Application with Actuator enabled for monitoring

docker buid . -t rajeshm9/webapp

docker run -p 8085:9080 rajeshm9/webapp (Tested it at local for Endpoint and prometheus url)

docker push (Image is in docker hub , pushed from my account)

2. Deployed the Tomcat Application on Minikube

kubectl apply -f deploy.yaml (Creation of Deployment using image created in step 1 ,configured liveness (port) and readiness (http) probe , mount access logs foldes) Kubectl apply -f Service.yaml (Exposing Deployment as service on port 8080)

Kubectl apply -f ingress/ingress-resource.yaml (Creation of ingress resource pointing to tomcat-service listening on port 8080)

3. Configuration of Prometheous for Monitoring

kubectl create configmap prometheus-cm --from-file prometheus.yml (Creation of config which contain the prometheus configuration for scraping application data points) kubectl apply -f prometheus-deploy.yaml (Creation of prometheus deployment and exposing service on Node port)

4. Configuration of EFK Stack for Logging Purpose

kubectl apply -f elastic.yaml (Elasticsearch Deployment on single node and exposing it on Node port http://192.168.1.8:32759/)

kubectl apply -f kibana.yaml (Kibana Deployment and exposing it node port http://192.168.1.8:31320/)

kubectl apply -f fluentd-rbac.yaml (Creation of Cluster Role for accessing the kube-namespace logs)

kubectl apply -f fluentd-daemonset.yaml (Creation on Fluentd Daemonset)
