Demonstrating Docker-Ready Solution for Django & PostgreSQL
Tested Infrastructure
| Platform | Number of Instance | Reading Time |
|---|---|---|
| Play with Docker | 1 | 5 min |
Pre-requisite
- Create an account with DockerHub
- Open PWD Platform on your browser
- Click on Add New Instance on the left side of the screen to bring up Alpine OS instance on the right side
Setup
Follow the below instructions.
- Cloning the Repository
git clone https://github.com/collabnix/dockerlabs
cd dockerlabs/solution/django-postgres/
Running Docker container
docker-compose run web django-admin.py startproject composeexample .
Once you run the above command, you might see containers coming up and running. Soon you will see port:8080 getting displayed on the top of PWD screen. Once clicked it might throw an error
"DisallowedHost at /
Invalid HTTP_HOST header: 'ip172-19-0-28-bfn8rk49cs9g00f9usn0-8080.direct.labs.play-with-docker.com'. You may need to add 'ip172-19-0-28-bfn8rk49cs9g00f9usn0-8000.direct.labs.play-with-docker.com' to ALLOWED_HOSTS."
To fix this issue, follow the below steps:
- Now there will be below folders and files present inside project folder
ls
composeexample
docker-compose.yml
Dockerfile
manage.py
requirements.txt
Configuring the settings
Inside composeexample/settings.py, Add below line at the end of the file. please change FQDN,IP according to your system.
ALLOWED_HOSTS = ['ip172-18-0-11-bfleibmac3u0009ab2vg-8080.direct.labs.play-with-docker.com', 'localhost', '127.0.0.1', '198.211.99.20']
Edit the composeexample/settings.py file and Replace the DATABASES = … with the following and save the file
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'postgres',
'USER': 'postgres',
'HOST': 'db',
PORT': 5432,
Brining up the Application Stack
