Crypto-App Repository

This application fetches the current prices of selected cryptocurrencies using the Coingecko API.

Contents

This repository contains the following directories:

main.py: This python file contains the source code for the flask-based application.

k8s: This file contains sample configurations of the YAML file for running the application in a kubernetes cluster.

Dockerfile: This is a simple Dockerfile for building a Docker image that runs a basic web application.

Getting Started

To get started, clone this repository to your local machine:

git clone https://github.com/iAlexeze/Crypto-App.git

Once you have cloned the repository, you can explore the contents of the directories and files and use them as a starting point for your own Docker projects.

To build the Docker image using the Dockerfile, follow the instructions below:

Build the Docker image:

docker build -t my-crypto-app .

This will create a Docker image named my-crypto-app based on the instructions in the Dockerfile.

Or, Pull the image directly from Dockerhub

Run:

docker pull ialexeze/cryptoprices:1.0.0

This will pull the application image from DockerHub into your local docker machine.

Either wyas, you should be able to see the images built or pulled, using the command:

docker images

Run the Docker container:

docker run -p 5000:5000 my-crypto-app

This will start a Docker container based on the my-crypto-app image and map port 5000 on your local machine to port 80 in the container.

Access the web application in your browser:

http://localhost:5000 (you can replace the localhost with your Node_IP if your kubernetes cluster is in the cloud)

You should see a web page displaying the current prices of top cryptocurrencies. Also, you would see the container ID of the docker container running the application as well as the your IP address

To run in Kubernetes Cluster

Kubectl apply -f k8s.yml

This will create a new deployment named crypto-prices as well as a Nodeport service named crypto-svc for external access

Access the application using http://localhost:31000 (you can replace the localhost with your Node_IP if your kubernetes cluster is in the cloud)
