# Feast Python / Go Feature Server Helm Charts

Current chart version is `{{ template "chart.version" . }}`

## Installation
### Python feature server
Docker repository and tag are required. Helm install example:
```
helm install feast-feature-server . --set image.repository=REPO --set image.tag=TAG
```

Deployment assumes that `feature_store.yaml` exists on docker image. Example docker image:
```
FROM python:3.8

RUN apt update && \
    apt install -y jq

RUN pip install pip --upgrade

RUN pip install feast

COPY feature_store.yaml /feature_store.yaml
```

### Go feature server
> Warning: this is experimental, and only supports a local file registry + Redis

Furthermore, if you wish to use the Go feature server, then you must install the Apache Arrow C++ libraries, and your `feature_store.yaml` should include `go_feature_server: True`.
For more details, see the [docs](https://docs.feast.dev/reference/feature-servers/go-feature-server).

The docker image might look like:
```
 FROM python:3.8

 RUN apt update && \
     apt install -y jq
 RUN pip install pip --upgrade
 RUN pip install feast
 RUN apt update
 RUN apt install -y -V ca-certificates lsb-release wget
 RUN wget https://apache.jfrog.io/artifactory/arrow/$(lsb_release --id --short | tr 'A-Z' 'a-z')/apache-arrow-apt-source-latest-$(lsb_release --codename --short).deb
 RUN apt install -y -V ./apache-arrow-apt-source-latest-$(lsb_release --codename --short).deb
 RUN apt update
 RUN apt -y install libarrow-dev

 COPY feature_store.yaml /feature_store.yaml
 ```
