Simple Crud Application Flask Dockerized

This is a simple API build using Flask and then has been converted to a Docker Container. Also, this is my first attempt to make a Dockerfile for an app.

How to run the app?

This is a basic API which just returns a number. To run the API follow the following steps:-

1. Make a virtualenv

virtualenv venv --python=python3 

2. Shift to virtualenv

source venv/bin/activate

3. Install the dependencies

pip --no-cache-dir --user install -r requirements.txt

4. Run the app

python app.py

How to run the Docker Container

This application has been converted to a docker container.

1. Install docker
2. To make image for the application

docker build -t flaskapp:latest .

This command will automaticaly make a docker image from the Dockerfile which we have. 3. To build a container out of the docker image

docker run -d -p 9000:5000 flaskapp

This will provide the service at port 9000 on the localhost. The Sevice form port 9000 would be mapped to port 5000 of the continer.
