Webb23 alm final project

Objective

In this assignment, you will containerize a Django application, deploy it using Kubernetes (Minikube), and set up GitHub Actions to automate testing.

Step 1: Fork the repository (Group)

Step 2: Set up Docker

1. Create a docker file

   • Use a python base image
   • Run this command to install all python package

     pip install -r requirements.txt 

   • The command for running the Django server

     python blog_project/manage.py runserver 0.0.0.0:8000

2. Build you docker image

3. Create a Docker container

Step 3: Set up Kubernetes (Minikube) (Group)

1. Create a kubernetes deployment yaml file, that uses the Docker image from step 2

   • remember to export port 8000

2. Crete a kubernetes service yaml file

3. Apply the kubernetes development and servics configuration

Step 4: Set up Github Action (Group)

1. Create a Github Action workflow for testing

   • The workflow should only work when creating a pull request to the main branch
   • Use a postgres db service with these enviroment variables

   POSTGRES_USER: postgres
   POSTGRES_PASSWORD: postgres
   POSTGRES_DB: django_db

   • Remember to use pip to install all package

   pip install -r requirements.txt 

   • The last step to run the test you need to run two commands

   run: |
       python blog_project/manage.py migrate
       python blog_project/manage.py test

2. Create pull request

Step 5: Create docker compose (Individual)

1. Create docker compose yaml configuration

   • Add db service
     • db should use an postgres image
     • Add this environment variable to the Db service

     POSTGRES_USER: postgres
     POSTGRES_PASSWORD: postgres
     POSTGRES_DB: django_db

     • Add a volume that the db service can use
       • with this /var/lib/postgresql/data
   • Add web service
     • Use local docker image
     • the command to run the django server

       python blog_project/manage.py runserver 0.0.0.0:8000

     • Dont forget to expose container port 8000
     • It should depend on db service

2. Build and start container

   • When its running run this command in a seperate terminal

   docker-compose exec web python blog_project/manage.py migrate

   • Create django admin user

   docker-compose exec web python blog_project/manage.py createsuperuser

   • try to login

   http://localhost:8000/admin/

REMEMBER TO REMOVE FROM .gitignore

• docker-compose.yml line 1
• Dockerfile line 2
