In this article, we’ll show you how to set up a Heroku app and a PostgreSQL database for the app’s backend data. You can use the following Homebrew command if you’re developing locally on a Mac: 1. Brew install. You’ll need to navigate to the Settings tab and then click View Credentials to see your Postgres username and password.
For other tools that you want to run on your own machine, you can set up a tunnel that pretends to be a Postgres server running on your machine but actually sends data over SSH to your PythonAnywhere Postgres instance. If you're using a Mac or Linux, you probably already have the right tool installed - the ssh command. If you're using Windows. In this article, we’ll walk through the process of installing a Postgres database on a Mac OS X machine and set it up for Ruby on Rails development. Install Postgres Database with Homebrew. Homebrew is a popular package manager for OS X. To install Postgres with Homebrew, follow the steps below. Here are the steps I used to set up Postgres in Mac OSX. The -U means to login using that username and the -W means to prompt for a password. To exit the shell hit Ctrl+d. Starting a new Rails project. In case you’re using this guide to get started using rails here’s how I would start the new rails app.
Estimated reading time: 7 minutes This quick-start guide demonstrates how to use Docker Compose to set up and run a simple Django/PostgreSQL app. Before starting,install Compose.
Define the project components
For this project, you need to create a Dockerfile, a Python dependencies file,and a
docker-compose.yml
file. (You can use either a .yml
or .yaml
extension for this file.)- Create an empty project directory.You can name the directory something easy for you to remember. This directory is the context for your application image. The directory should only contain resources to build that image.
- Create a new file called
Dockerfile
in your project directory.The Dockerfile defines an application’s image content via one or more build commands that configure that image. Once built, you can run the image in a container. For more information onDockerfile
, see the Docker user guide and the Dockerfile reference. - Add the following content to the
Dockerfile
.ThisDockerfile
starts with a Python 3 parent image. The parent image is modified by adding a newcode
directory. The parent image is further modified by installing the Python requirements defined in therequirements.txt
file. - Save and close the
Dockerfile
. - Create a
requirements.txt
in your project directory.This file is used by theRUN pip install -r requirements.txt
command in yourDockerfile
. - Add the required software in the file.
- Save and close the
requirements.txt
file. - Create a file called
docker-compose.yml
in your project directory.Thedocker-compose.yml
file describes the services that make your app. In this example those services are a web server and database. The compose file also describes which Docker images these services use, how they link together, any volumes they might need mounted inside the containers. Finally, thedocker-compose.yml
file describes which ports these services expose. See thedocker-compose.yml
reference for more information on how this file works. - Add the following configuration to the file.This file defines two services: The
db
service and theweb
service. - Save and close the
docker-compose.yml
file.
Create a Django project
In this step, you create a Django starter project by building the image from the build context defined in the previous procedure.
- Change to the root of your project directory.
- Create the Django project by runningthe docker-compose run command as follows.This instructs Compose to run
django-admin startproject composeexample
in a container, using theweb
service’s image and configuration. Because theweb
image doesn’t exist yet, Compose builds it from the current directory, as specified by thebuild: .
line indocker-compose.yml
.Once theweb
service image is built, Compose runs it and executes thedjango-admin startproject
command in the container. This command instructs Django to create a set of files and directories representing a Django project. - After the
docker-compose
command completes, list the contents of your project.If you are running Docker on Linux, the filesdjango-admin
created are owned by root. This happens because the container runs as the root user. Change the ownership of the new files.If you are running Docker on Mac or Windows, you should already have ownership of all files, including those generated bydjango-admin
. List the files just to verify this.
Connect the database
In this section, you set up the database connection for Django.
- In your project directory, edit the
composeexample/settings.py
file. - Replace the
DATABASES = ...
with the following:These settings are determined by thepostgres Docker imagespecified indocker-compose.yml
. - Save and close the file.
- Run the docker-compose up command from the top level directory for your project.At this point, your Django app should be running at port
8000
onyour Docker host. On Docker Desktop for Mac and Docker Desktop for Windows, gotohttp://localhost:8000
on a web browser to see the Djangowelcome page. If you are using Docker Machine,thendocker-machine ip MACHINE_VM
returns the Docker host IPaddress, to which you can append the port (<Docker-Host-IP>:8000
).Note:On certain platforms (Windows 10), you might need to editALLOWED_HOSTS
insidesettings.py
and add your Docker host name or IP address to the list. For demo purposes, you can set the value to:This value is not safe for production usage. Refer to the Django documentation for more information. - List running containers.In another terminal window, list the running Docker processes with the
docker container ls
command. - Shut down services and clean up by using either of these methods:
- Stop the application by typing
Ctrl-C
in the same shell in where you started it: - Or, for a more elegant shutdown, switch to a different shell, and run docker-compose down from the top level of your Django sample project directory.
Once you’ve shut down the app, you can safely remove the Django project directory (for example,
rm -rf django
).More Compose documentation
