Deploy Django app on Heroku (Quick Guide)

Heroku is a platform as a service type cloud. It supports many languages like -

Python    |    php    |     Go   |     Scala    |     Ruby on Rails    |  Node.js   |    Java

 

 

 Here i am discussing about how to deploy your django app on heroku. So I am considering that your django app is ready to deploy...

 

Things you should learn before deploy -

1 - PostgreSQL (Heroku only support postgresql ,it must be installed locally on PC).

2 - Virtualenv (It creates a virtual environment, which separates required dependencies from all installed dependencies ).  [  pip install virtualenv ]

3 - Procfile (It is a simple text file , which declares the command to start the app).

4 - Dynos , requirement.txt file.

5 - Git and Github.

Steps to deploy -  

> Download HEROKU-TOOLBELT from heroku website.

> Open the heroku CLI and run these commands ---

       

$ git clone https://github.com/heroku/python-getting-started.git
$ cd python-getting-started

> It will create a folder in your local machine along with requirement.txt file.

        Folder PATH in local machine -- C:\Users\shivam\python-getting-started

> Create app on heroku cloud with random name - ( Ex - lit-bastion-5032)

$ heroku create
Creating lit-bastion-5032 in organization heroku... done, stack is cedar-14
http://lit-bastion-5032.herokuapp.com/ | https://git.heroku.com/lit-bastion-5032.git
Git remote heroku added

> Now push your project to heroku -

$ git push heroku master
