registry:
    registry_type: sql
    path: mysql://user:password@x.x.x.x:3306/feast  
offline_store:
  type: file
entity_key_serialization_version: 2

Run: helm install feast-feature-server feast-charts/feast-feature-server --set feature_store_yaml_base64=$(base64 feature_store.yaml)

Ah good catch!

Would you mind making a PR to fix this? Should be in https://github.com/feast-dev/feast/blob/master/sdk/python/feast/infra/feature_servers/multicloud/Dockerfile and https://github.com/feast-dev/feast/blob/master/sdk/python/feast/infra/feature_servers/multicloud/Dockerfile.dev
