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
