jeshocarmel/ip_location_mapper

IP Location Tracker

An app to trace the location of an IP address. The IP address is provided as input and the GPS coordinates for that IP is shown in a map.

Flow:

• API requests are made to ipstack.com to get the coordinates.
• The results are stored in a redis cache with TTL 24 hours.

Architecture

Prerequisites

• an api key from ipstack (free with 10,000 api requests per month )

To start on a development machine

    docker-compose up --build

To build the project and push to dockerhub

    make push

Note: kindly go through the Makefile before performing a push. The dockerhub repository in Makefile points to jeshocarmel/ip_location_mapper

To start the project on minikube

1. start minikube

minikube start

2. create secret

kubectl apply -f app-secret.yaml
kubectl describe secrets/app-secret

3. add helm repo to install redis cluster

helm repo add bitnami https://charts.bitnami.com/bitnami
helm install my-release bitnami/redis --values minikube_files/values-minikube.yml

4. create configmap

kubectl apply -f app-configmap.yaml
kubectl describe configmap/app-configmap

5. create deployment and service

kubectl apply -f app-deployment.yaml

6. view everything you have created

kubectl get all

7. expose service via minikube

minikube service go-app-service

Additional Info

Checking logs of pods

• to view last 20 lines

kubectl logs --tail=20 deployment/go-app

• to stream logs

kubectl logs -f deployment/go-app

To delete everything (pods + deployment + service + statefulset) initiate the following commands

kubectl delete deployment/go-app
kubectl delete service/go-app-service
helm delete my-release
minikube delete
