Feast Chart

This directory provides the Helm chart for Feast installation.

This chart installs Feast Core and Feast Serving components of Feast, along with the required and optional dependencies. Components and dependencies can be enabled or disabled by changing the corresponding enabled flag. Feast Core and Feast Serving are subcharts of this parent Feast chart. The structure of the charts are as follows:

feast  // top level feast chart
│
├── feast-core  // feast-core subchart
│   ├── postgresql  // Postgresql dependency for feast-core (Feast database)
│   └── kafka  // Kafka dependency for feast-core (default stream source)
│
├── feast-serving-online  // feast-serving subchart
│    └── redis  // Redis dependency for installation of store together with feast-serving
│
└── feast-serving-batch  // feast-serving subchart

Prerequisites

Kubernetes 1.13 or newer cluster
Helm 2.15.2 or newer

Resources Required

The chart deploys pods that consume minimum resources as specified in the resources configuration parameter.

Installing the Chart

Add repository for Feast chart:

helm repo add feast-charts https://feast-charts.storage.googleapis.com
helm repo update

Install Feast release with minimal features, without batch serving and persistence:

RELEASE_NAME=demo
helm install feast-charts/feast --name $RELEASE_NAME -f values-demo.yaml

Install Feast release for typical use cases, with batch and online serving:

# To install Feast Batch serving, BigQuery and Google Cloud service account
# is required. The service account needs to have these roles: 
# - bigquery.dataEditor
# - bigquery.jobUser
#
# Assuming a service account JSON file has been downloaded to /home/user/key.json,
# run the following command to create a secret in Kubernetes
# (make sure the file name is called key.json):
kubectl create secret generic feast-gcp-service-account --from-file=/home/user/key.json

# Set these required configuration in Feast Batch Serving
STAGING_LOCATION=gs://bucket/path
PROJECT_ID=google-cloud-project-id
DATASET_ID=bigquery-dataset-id

# Install the Helm release using default values.yaml
helm install feast-charts/feast --name feast \
  --set feast-serving-batch."application\.yaml".feast.jobs.staging-location=$STAGING_LOCATION \
  --set feast-serving-batch."store\.yaml".bigquery_config.project_id=$PROJECT_ID \
  --set feast-serving-batch."store\.yaml".bigquery_config.dataset_id=$DATASET_ID

Ingress Parameters

The following table lists the configurable parameters of the ingress section for each Feast module.

Note, there are two ingresses available for each module - grpc and http.

Parameter	Description	Default
`ingress.grcp.enabled`	Enables an ingress (endpoint) for the gRPC server	`false`
`ingress.grcp.*`	See below
`ingress.http.enabled`	Enables an ingress (endpoint) for the HTTP server	`false`
`ingress.http.*`	See below
`ingress.*.class`	Value for `kubernetes.io/ingress.class`	`nginx`
`ingress.*.hosts`	List of host-names for the ingress	`[]`
`ingress.*.annotations`	Additional ingress annotations	`{}`
`ingress.*.https.enabled`	Add a tls section to the ingress	`true`
`ingress.*.https.secretNames`	Map of hostname to TLS secret name	`{}` If not specified, defaults to `domain-tld-tls` e.g. `feast.example.com` uses secret `example-com-tls`
`ingress.*.auth.enabled`	Enable auth on the ingress (only applicable for `nginx` type	`false`
`ingress.*.auth.signinHost`	External hostname of the OAuth2 proxy to use	First item in `ingress.hosts`, replacing the sub-domain with 'auth' e.g. `feast.example.com` uses `auth.example.com`
`ingress.*.auth.authUrl`	Internal URI to internal auth endpoint	`http://auth-server.auth-ns.svc.cluster.local/auth`
`ingress.*.whitelist`	Subnet masks to whitelist (i.e. value for `nginx.ingress.kubernetes.io/whitelist-source-range`)	`"""`

To enable all the ingresses will a config like the following (while also adding the hosts etc):

feast-core:
  ingress:
    grpc:
      enabled: true
    http:
      enabled: true
feast-serving-online:
  ingress:
    grpc:
      enabled: true
    http:
      enabled: true
feast-serving-batch:
  ingress:
    grpc:
      enabled: true
    http:
      enabled: true
