# django-kubernetes-azure
Django project Deployment on Azure Container Machine using Kubernetes as orchestration Tool.
### Preliminary steps
- Clone this repo source code :
```
https://github.com/inforian/django-kubernetes-azure.git
```
- Run python manage.py runserver , and visit Browser you will see pink theme Template.
### Publish Docker Containers
- Install [Docker](https://docs.docker.com/engine/installation/)
- Build docker image for pink theme :
```docker
docker build -t dj:pink . ## (assuming you are inside django project)
```
- Now , Build Image for Orange theme BUt before that edit template index.html
and copy paste below code inside `` tag.
```html
#banner {
background-color: #ffa500;
}
```
- Refresh Django dev server url you will see ornage theme.
- Build image for Orange theme
```docker
docker build -t dj:orange .
```
- Check your iamges :
```docker
docker images | grep dj
```
- Now Login to you docker hub Account and push this image to docker-hub:
```docker
docker login
# for orange
docker tag {image_id} {docker_hub_username}/dj:orange
# for pink
docker tag {image_id} {docker_hub_username}/dj:pink
```
### Azure
- Create a Resource on Azure, You have to choose Azure Container service from Azure portal from their
you can choose any `kubernetes` as orchestration type.
- After your Machine is up and Running connect with you `Master VM` via `SSh`
- Copy files from `kubernetes_config` to `Master VM`
- You must have 3 files on `Master VM`
- rc-orange.yaml
- rc-pink.yaml
- service.yaml
### Kubernetes
- Create replication controller for pink theme (I have created only one rc so only one pod will be created):
```
kubectl create -f rc-pink.yaml
```
-
- Create service with :
```
kubectl create -f service.yaml
```
- List your service to check status (Wait for some time till external ip assigned to your service) :
```
kubectl get service | grep my-dj-app
```
- If external ip is assigned to your service then visit app url which will be like:
```
http://{external-ip}:8000 # you will see pink theme
```
### Play with Kubernetes and see its Magic :
- Now create replication controller for orange theme, I have created 3 `Rc's` here :
```
kubectl create -f rc-orange.yaml
```
- Check newly created `RC` and wait for it un-till it is ready with :
```
kubectl get rc | grep dj-orange
```
- Note : No new service will be craeted here but we have bind orange-theme `RC`
with already existing Service (which craeted above).
- Refresh web url(refresh it every other second by pressing f5) , you will see web theme is switching
from pink to orange and vice-versa on every refresh or some time remain as it was before.
- Now we will Scale down pink theme replica to `0` , visit web url now only orange theme will work
```
kubectl scale rc/dj-pink --replicas=0
```
- Scale up Pink theme `RC` again to `1` and - orange to `0`
```
kubectl scale rc/dj-pink --replicas=1
kubectl scale rc/dj-orange --replicas=0
```
- Now only pink theme will work, this way you can easily roll out
your new version of site, or we you want to scale you `RC's` according to traffic
on your sites's , you can scale them using above commands.
