Deployment of a Microservices Application on K8s- Do MongoDB App Deployment

Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications.

In this blog we will deploy Flask app on K8 using https://killercoda.com/.

login to the killercoda and choose kubernetes.

DEPLOYING FLASK APP :

• Clone the Repository https://github.com/LondheShubham153/microservices-k8s.git

git clone https://github.com/LondheShubham153/microservices-k8s        

• Do cd into the directory for yml files.

cd /microservices-k8s/flask-api/k8s        

• Next we need to apply the Task service file as it is with name taskmaster-svc.yml with using below commands.

kubectl apply -f taskmaster.yml

kubectl apply -f taskmaster-svc.yml        

Deploy MongoDB

• Deploy MongoDB component using below commands

kubectl apply -f mongo-pv
kubectl apply -f mongo-pvc.yml
kubectl apply -f mongo.yml        

Once all pods are deployed, run the below commands to check the pods and services

NOTE: Check pods are in running state or not

kubectl get pods        

To check the services use below command

kubectl get svc        

curl -d '{"task":"DB ka assignment ho gaya re baba"}' -H "Content-Type: application/json" -X POST https://127.0.0.1:30007/task

curl https://127.0.0.1:30007/tasks        

Now open your browser and enter https://ec2-public-ip:30007 to get the app status.
