## Helm chart now available
This repo is now being deprecated in favour of a Helm compatible [chart](https://github.com/AlexsJones/nifi)
_I am going to appeal to add it into helm/charts as soon as my dependent zookeeper chart is added_
Thank you!
### Prerequisites
- This example is using Google Cloud Platform persistent volumes for its backing store (easy to convert to AWS).
- There is no longer a requirement to install [vortex](https://github.com/AlexsJones/vortex) for interpolation.
- For setting up the environment run:```
docker run -v $PWD:/tmp tibbar/vortex:v1 -template /tmp/templates -output /tmp/deployment -varpath /tmp/environments/default.yaml
```This will generate your default environment
- Requires [zookeeper](https://github.com/AlexsJones/kubernetes-zookeeper-cluster)
```
# Assumes you've checked it out next to the nifi cluster...
cd kubernetes-zookeeper-cluster
docker run -v $PWD:/tmp tibbar/vortex:v1 -template /tmp/templates -output /tmp/deployment -varpath /tmp/environments/small.yaml
kubectl create -f deployment/
cd ../kubernetes-nifi-cluster
```Now zookeeper is setup with three nodes on the zk namespace you are ready!
## Deploy Nifi
_Make sure zk is running to avoid headaches_
```
# Please create the nifi namespace first
# Ensure you have run docker vortex build step mentioned above^kubectl create ns nifi
kubectl create -f deployment/
```Once running you should see...
```
kubectl get pods -n nifi

## UI
Port forward to the UX:
```
kubectl port-forward nifi-0 8080:8080 -n nifi
````http://:8080/nifi/`
## Scaling
`kubectl scale --replicas sts/nifi`
## Configuration
The `environments/` folder can have new files added and used with `build_environment.sh ` and those values interpolated
For more informatino on this please see [here](https://github.com/AlexsJones/vortex/blob/master/README.md)### Production readiness
A checklist for consideration I would think about before you want to run this in prod
- Use an identity aware proxy infront of the load balancer
- Recovery procedure from the PVC's
- Scaling, liveliness & readiness probes
