cat << EOF > kubernetes/deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: stateless-flask
namespace: stateless-flask
spec:
replicas: 3
selector:
matchLabels:
app: stateless-flask
template:
metadata:
labels:
app: stateless-flask
spec:
containers:
- name: stateless-flask
image: $DOCKERHUB_USERNAME/stateless-flask:v0
