Travis CI Integration
Setup
In the docker-compose.yml file in the app section under command enter your Django project name
In the .env file enter your Django project's secret key under secret key
Place the entire contents of your Django project inside the app/ folder
In the Dockerfile inside the app/ directory if you are using Python 3 uncomment the FROM python:3-onbuild command and comment out the FROM python:2-onbuild we are using the onbuild version so it will automatically load the requirements.txt file
If you have a requirements.txt file append the contents of the requirements.txt in this project to yours.
In your settings.py file replace your
SECRET KEY with os.environ['SECRET_KEY']
DEBUG with True if os.getenv('DEBUG') == 'true' else False
In the DATABASES section of settings.py replace your
NAME with os.environ['DB_NAME']
USER with os.environ['DB_USER']
PASSWORD with os.environ['DB_PASS']
HOST with os.environ['DB_HOST']
PORT with os.environ['DB_PORT']
You have made your Django project get the database and secret key data from the environment variables which are defined in the .env file from earlier.
Add '*'as one of your hosts in ALLOWED_HOSTS (don't know if this is needed, had to do this to get it to work on my machine)
Travis CI Setup
Insert your Django project SECRET_KEY between the quotes under the env section
Enter a name for your database under DB_NAME and the same name inside the psql command under before_script
Docker Deployment
Run docker-compose build
After building run docker-compose up
In your browser go to your docker machine's IP address and you should see your app
If the CSS isn't loading run docker-compose run app /usr/local/bin/python manage.py collectstatic and then reload
