This repo is for sample python containerise project provision via K8s on minikube, Repo consist of:

1. Sample python code for hello-world that uses Flask (HTTP server for app).
2. Docker file to launch container with base alpine image for python 3.7.
3. K8s declarative configuration file to run 2 replica of app via deployment object,which are exposed internally to other objects via cluster-ip service on port 5000.
4. External traffic allowed via Ingress service with configuration available in ingress-service.yaml.

This project require minikube and kubectl configured. I am using community led project for ingress-nginx setup available on https://github.com/kubernetes/ingress-nginx To make use on community led NGINX Ingress controller there are some mandatory configuration require. If you already have minikube and kubectl configured.

Follow instruction:-

1. Below command will create Namespaces, configmap, serviceaccount, clusterrole and deployment for nginx-ingress-controller.

   Run: kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/mandatory.yaml Run: minikube addons enable ingress

2. Once configured code copied. Run command from project root folder.

   Run: kubectl apply -f k8s

3. To access Hello world app please hit minikube IP address. Ip address available via command 'minkube ip'

1.Docker file to launch container with base alpine image for python 3.7:

Base alpine image of python 3.7 get downloaded from docker hub. Additional requirement to run the project get installed and default command has been changeed.

2.Deployment object to run 2 replica of sample application:

Post docker build, updated image get pushed into docker hub. Instructions are shared in deploy.sh. Deployment object pythapp-deployment.yaml is configured to run 2 replicas of the image shared on docker hub.

3.ClusterIp service to expose pod to internal objects on port 5000, configuration availlable on pythapp-cluster-ip-service.yaml.

4.To allow traffic externally Ingress-nginx service object has been created with configuration available on ingress-service.yaml.
