Autogenerated from chart metadata using [helm-docs v1.5.0](https://github.com/norwoodj/helm-docs/releases/v1.5.0)
40+
41+
42+
Docker repository and tag are required. Helm install example:
43+
```
44+
helm install feast-python-server . --set image.repository=REPO --set image.tag=TAG
45+
```
46+
47+
Deployment assumes that `feature_store.yaml` exists on docker image. Example docker image:
48+
```
49+
FROM python:3.7
50+
51+
RUN apt update && \
52+
apt install -y jq
53+
54+
RUN pip install pip --upgrade
55+
56+
RUN pip install feast
57+
58+
COPY feature_store.yaml /feature_store.yaml
59+
```
60+
61+
Make sure that you have enabled the flags for the python server. Example `feature_store.yaml`:
62+
```
63+
project: feature_repo
64+
registry: data/registry.db
65+
provider: local
66+
online_store:
67+
path: data/online_store.db
68+
flags:
69+
alpha_features: true
70+
python_feature_server: true
71+
```
