Github SSH Action Configuration to Deploy Changes in a Django Application

Deploying updates to your Django application can be notoriously tricky, especially when you try to automate it using tools like GitHub Actions. A common issue that developers face is getting their environment settings, particularly the SECRET_KEY, correctly configured for successful deployment. This post outlines how to set up your GitHub Actions for deploying changes to a Django application using SSH and offers a solution to a common problem regarding environment variables.

The Problem

Imagine you've set up a workflow to execute a script that handles essential tasks like making migrations, migrating your database, loading static files, restarting Gunicorn, and reloading Nginx. You are excited to automate this process, but then you encounter a frustrating error:

This error occurs because your script is trying to run without the necessary environment variables, which should be set in your settings.py for Django to function correctly during deployment.

The Solution

Fortunately, there's a simple and effective way to configure your GitHub SSH action to ensure your environment variables, including the SECRET_KEY, are available during the deployment process.

Updated Action Configuration

Here’s how you can modify your GitHub Actions YAML file to correctly set your environment variables:

Key Changes Explained

Set the env Parameter:

Use the env field in the action to pass the necessary environment variables to your deployment script. In this case, DJANGO_SECRET_KEY is specified.

Export the Variables:

The line export DJANGO_SECRET_KEY=$DJANGO_SECRET_KEY makes the environment variable available to the shell session that runs your deploy_changes.sh script.

Use the Correct Branch:

Ensure you are pushing to the correct branch. GitHub has renamed the default branch from master to main, so check that your configuration reflects this.

Additional Considerations

Using dotenv: If you're utilizing a .env file on your server and loading variables using the python-dotenv package in your Django settings, ensure that your deployment script appropriately sources your environment settings.

Script Verification: After executing your deployment script, it might be helpful to include a command like ls -al to verify the working directory and confirm that the deployment process has completed.

Summary

By properly configuring your GitHub Actions to pass environment variables, you can resolve the common issue of missing environment variables during automated deployments. With the right setup, your GitHub Actions workflow can work seamlessly to handle deployment tasks for your Django application, ensuring that tasks like makemigrations and migrate run without throwing errors.

Take some time to review the setup outlined in this post, and you should be on your way to developing a more efficient and automated deployment process for your Django applications. Happy coding!
