Just install the requirements and run the app
cd webapp/
pip install -r requirements.txt
flask run
curl localhost:5000
You can use the already built docker image albertoal/flask_webapp or build your own then run it.
From the root dir:
docker build -t myflask_app .
docker run -it --rm -p 5000:5000 myflask_app
curl localhost:5000
For Minikube I created an Ingress controller in order to get external access to the service. This example requires the Minikube ingress addon enabled If you are deploying the manifest to a different Kubernetes cluster, check out the different Ingress Controllers available.
minikube start
minikube addons enable ingress
kubectl apply -f kubernetes.yaml
minikube ip
> 192.168.20.100
curl 192.168.20.100/ready
I wanted to test Envoy proxy sidecar with this app. This is available on envoy/envoy.yaml.
Note that this doesn't implement an Envoy proxy ingress gateway, just the proxy sidecar.
