Django + Postgres + Skaffold + Kubernetes

Example Django application running on Postgres with Kubernetes deployment using Skaffold. See skaffold.yaml for Skaffold configuration.

⚠️ Pre-requisites

• Minikube or Docker Desktop
• kubectl
• Skaffold
• Optional: kustomize

Getting started

The project uses Skaffold to build resources and deploy to Kubernetes. See the configuration in ./skaffold.yaml and manifests in k8s/ folder.

If you want to persist Postgres data, you can create a folder such as ~/postgres-data and mount it to Minikube:

$ mkdir ~/postgres-data
$ minikube mount ~/postgres-data:/mnt1/postgres-data

Build images:

$ skaffold build

Deploy in development mode with hot reloading of code:

$ skaffold dev [--port-forward]

You can test the deployment by making a request to localhost:8080:

$ curl http://localhost:8080/status/
{ "message": "OK" }

Run build and deploy once:

$ skaffold run [--tail] [--port-forward]

Delete resources:

$ skaffold delete

See what Skaffold deploys:

$ skaffold render

Connect to Postgres at forwarded port (here assumed to be 5433):

$ psql -p 5433 -h 127.0.0.1 -Upostgres-user django-db

Debugging

List pods:

$ kubectl get pods

Access Python in Django pod (replace pod name with your store pod):

$ kubectl exec $PODNAME -it -- python manage.py shell

Access psql in Postgres container:

$ kubectl exec postgres-statefulset-0 -it -- psql -Upostgres-user -ddjango-db
