# Helm Chart for Azure Functions on Kubernetes
## Installing
There are a few settings you should override:
- `functionApp.name` - name of your function apps your using
- `resources.requests.cpu` - required for Pod Autoscaler to work
- `image.repository` - Should be your image with your function app running in it (see http://www.jamessturtevant.com/posts/Running-the-Azure-Functions-runtime-in-kubernetes/ for creating a docker image with the azure functions runtime in it)
- `scale.maxReplicas` - max number of replicas
- `scale.minReplicas` - min number of replicas
- `scale.cpuUtilizationPercentage` - cpu percentage
An example would be:
```bash
helm install --set functionApp.name=sampleapp \
--set resources.requests.cpu=200m \
--set image.repository=vyta/functions \
--set scale.maxReplicas=10 \
--set scale.minReplicas=1 \
--set scale.cpuUtilizationPercentage=50 \
./az-func-k8
```
## Debugging
If you want to see what install might look like:
```bash
helm install --debug --dry-run --set resources.requests.cpu=200m ./az-func-k8
```
## Test the scaling
Test that the scaling works:
```bash
docker run -it busybox /bin/sh
#
\#: while true; do wget -q -O- http:///api/httpfunction?name=testingload; done
```
In a separate terminal run:
```bash
kubectl get hpa
kubectl get deploy
```
