GitHub Actions

Description

In our application GitHub Actions is used to automatically build, test and deploy our Django application to our servers.

CI/CD practices are all represented in one file - djangoapp.yml

The workflow is being triggered by the pull requests and push (only when changes are made within the vagrant/djangoapp/** path) on the main branch.

There 3 jobs inside:

  1. build: It actually builds the application on the control1 server, tests it and then push the image to the GitHub Registry.
  2. deploynode1: It pulls the application image from the GitHub Registry and builds the containers using the database and application images on the node1.
  3. deploynode2: It pulls the application image from the GitHub Registry and builds the containers using the database and application images on the node2.

All three nodes are registered as the self-hosted runners.

Possibly, it is a temporary solution that I will remake later by changing the way of the image deployment to the servers.

Pre-running steps

  1. Register all three machines as the self-hosted runners.
  2. Make sure that the gnupg2 is installed and configured on all three servers (recommended to do from the ~/actions-runner folder):
sudo apt-get install pass gnupg2
gpg2 --gen-key
pass init $gpg_id
  1. If you have followed the steps from the Ansible tutorial, you should already have Docker and Docker-compose installed on your nodes.
  2. Make sure to create all the required secrets from djangoapp.yml in the GitHub repository. Also, make sure to change the DB_HOST variable values to the ones corresponding to your servers' IPs.

After-running steps

Don't forget to create your Django Admin SuperUser:

  1. Find your docker container ID:
sudo docker container ls

Copy the ID of your application_1 Docker container here. 2. Enter your container bash interactively:

sudo docker exec -it <your container id> bash
  1. Create the Django Admin SuperUser:
python manage.py createsuperuser

You can check if the application works properly on: http://{your_node_IP}:8000/

P.S: docker-compose.yaml is not used in the workflow because there is an issue when the node tries authenticating to Docker.
