Docker Link - https://cloud.docker.com/repository/docker/ranaas/hw3

Steps to run my app using docker (follow any one of them)

• Using Docker

docker pull ranaas/hw3:latest
docker run -d -p 8081:80 ranaas/hw3:latest

• Using googledrive Download link

docker load -i cloud_project1.tar
docker run -d -p 8081:80 ranaas/hw3:latest 

• I have combined HW2 REST API and HW3 WebApp and port it to a docker container.

• Creating Docker instance acts as a more portable and modular framework for hosting services.
• Docker helps for Isolation, Modularity, Scalability. It also increases the speed for deploying an application without having to worry about the overheads.

Steps to install Docker:

• Set up the Repository

 
 sudo apt-get update
 sudo apt-get install docker.io
 sudo usermod -a -G docker [username] (In my case it was ubuntu) 
 

My Dockerfile looks like this (vim Dockerfile) :

FROM python:3.6

WORKDIR HW3

COPY ./requirements.txt /HW3/requirements.txt

RUN pip install -r requirements.txt

COPY . /HW3

RUN chmod +x startme.sh

CMD ["./startme.sh"]

I Created a Makefile for the ease of running commands (vim Makefile) :

# builds docker file
docker-build:
        docker build -t ranaas/hw3:latest .
        
# pushes the docker file to dockerhub
docker-push:
        docker push ranaas/hw3:latest

# runs the docker image on my local machine
docker-run-dev:
        docker run -p 5000:80 ranaas/hw3:latest 

# runs the docker image on server
docker-run-prod:
        docker run -p 8081:80 ranaas/hw3:latest 

# view the content of the image
docker-run-it:
        docker run -ti ranaas/hw3:latest sh

My startme.sh looks like this(vim startme.sh) :

#!/bin/bash

python3 app.py
