Chating-App

This is a example of 3 microservices and a database working in a Kubernetes cluster.

• chat_front: Simple webpage that sends and receives messages from chat_svc through socket io
• chat_svc: Receives messages from chat_front and sends these messages to chat_db to store this information
• chat_db: Receives data from chat_svc and stores this information in a SQLite DB.

Architecture

Steps

1. Create the docker images:

docker build -t chat_db:v1 ./chat_db/
docker build -t chat_svc:v1 ./chat_svc/
docker build -t chat_front:v1 ./chat_front/

2. Update the clusterIP in helm chart values.yaml

clusterIP: 13.233.122.155

3. Check your helm chart:

helm upgrade --dry-run --install chating-app ./helm_chart/

4. Install the helm chart:

helm upgrade --install chating-app ./helm_chart/

5. Verify that all pods are OK:

kubectl get pods

5. Open the link as mentioned and see the magic :) http://namespace.chat_front_serviceName.clusterIP.clusterDomain
