# GitOps with Django & ArgoCD - Part I
This is Django Starter Template which will be used in GitOps demo using ArgoCD.
### Prerequisites
- [x] [Docker](https://www.docker.com/) - Docker helps developers bring their ideas to life by conquering the complexity of app development.
- [x] [Kubernetes](https://kubernetes.io/) - also known as K8s, is an
open-source system for automating deployment, scaling, and management of containerized applications.
- [x] [ArgoCD](https://argo-cd.readthedocs.io/en/stable/) - Argo CD is implemented as a kubernetes controller which continuously monitors running applications and compares the current, live state against the desired target state
### ArgoCD Installation
Follow the official docs of ArgoCD installation.
* Before that make sure Docker Desktop or Minikube is running on your machine with K8s enabled.
- [https://argo-cd.readthedocs.io/en/stable/](https://argo-cd.readthedocs.io/en/stable/)
#### Commands
```
kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
```
### DockerHub
Images are being hosted in DockerHub.
- [https://hub.docker.com/r/mukulmantosh/app-sample](https://hub.docker.com/r/mukulmantosh/app-sample)
#### Dockerfile
```dockerfile
FROM python:3.10-alpine
# set work directory
WORKDIR /usr/src/app
# set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
# install dependencies
RUN pip install --upgrade pip
COPY ./requirements.txt /usr/src/app
RUN pip install -r requirements.txt
# copy project
COPY . /usr/src/app
EXPOSE 8000
RUN python manage.py migrate
RUN python manage.py create_dummy_user
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]
```
### Flow
- Make sure Docker is Up and Running
- Build & Upload the image to docker registry
- Clone this repository : [https://github.com/mukulmantosh/django-app-k8s](https://github.com/mukulmantosh/django-app-k8s)
- Update ```repoURL``` in the manifest file ```argo-app.yml```
- Update the manifest files pointed in the ```dev``` path
- Make sure to point properly to the correct image registry
- Next, follow the steps given in the ```django-app-k8s``` repository
