Deploy a Django application on Azure VM using Github Actions - django

Question

I have built a Django application and dockerized it with Nginx, I also created a GitHub workflow to build the docker image and push it to ghcr.io.
Now I want to deploy the docker image (from ghcr.io) to the Azure virtual machine (ubuntu). but I couldn't find, how to connect azure VM to GitHub workflow and execute some commands from it.
name: CI and CD
on: [push]
env:
DOMAIN_NAME: ${{ secrets.DOMAIN_NAME }}
jobs:
build:
name: Build Docker Images
runs-on: ubuntu-latest
steps:
- name: Checkout master
uses: actions/checkout#v1
- name: Add environment variables to .env
run: |
echo DJANGO_SECRET_KEY=${{ secrets.DJANGO_SECRET_KEY }} >> .env
echo DJANGO_ALLOWED_HOSTS=${{ secrets.DJANGO_ALLOWED_HOSTS }} >> .env
echo DATABASE=postgres >> .env
echo DB_NAME=${{ secrets.DB_NAME }} >> .env
echo DB_USER=${{ secrets.DB_USER }} >> .env
echo DB_PASS='${{ secrets.DB_PASS }}' >> .env
echo DB_HOST=${{ secrets.DB_HOST }} >> .env
echo DB_PORT=${{ secrets.DB_PORT }} >> .env
echo VIRTUAL_HOST=$DOMAIN_NAME >> .env

echo WEB_IMAGE=ghcr.io/$(echo $GITHUB_REPOSITORY | tr '[:upper:]' '[:lower:]')/web >> $GITHUB_ENV
echo NGINX_IMAGE=ghcr.io/$(echo $GITHUB_REPOSITORY | tr '[:upper:]' '[:lower:]')/nginx >> $GITHUB_ENV
- name: Login to GitHub Container Registry
uses: docker/login-action#v1

You can set up GitHub Action self-hosted runner on Azure VM to run GitHub Actions on the Azure VMto deploy a Django application
Firstly, you need to install the GitHub Action self-hosted runner on Azure VM by SSH into the VM and running below commands:
mkdir actions-runner && cd actions-runner
curl -o actions-runner-linux-x64-2.278.0.tar.gz -L https://github.com/actions/runner/releases/download/v2.278.0/actions-runner-linux-x64-2.278.0.tar.gz #Extract the installer
tar xzf ./actions-runner-linux-x64-2.278.0.tar.gz
Now you need to configure the VM to communicate with your GitHub account by using below command:
./config.sh --url https://github.com/{{Yourorganization}} --token <YOURTOKENFROMGITHUB>
You will be prompted through the registration process of your GitHub Action self-hosted runner
Then install the needed dependencies for your Django Application to the VM
Now you can run your GitHub Action Workflow
