Helm charts

This chart adds all the components required to run feast, sans the stores to which you might want to ingest your features. Those will have to be deployed seperately.

Installing the chart

helm dep update
helm install --name feast .

Requirements

External Permissions

The feast deployment requires access to the following components:

  • gcs: read/write

As well as the following, depending on your use case:

  • bigquery: read/write
  • bigtable: read/write/tableAdmin

The recommended way to give your deployment these permissions is to deploy Feast on a cluster with the required permissions.

Components

The components included in this chart are:

  • feast-core: the main API controller of feast
  • feast-metadata: postgres db that persists feast's metadata
    • The stable postgres chart is being used for this deployment - any of the parameters described here can be overridden to customise your postgres deployment.
  • feast-serving: service that serves up features from the various serving stores

Components that Feast supports, but this installation will not include are:

  • Storage
    • Redis or Postgres dbs for feature storage
  • TICK stack for metrics monitoring
    • Set statsd.host and statsd.port to direct job metrics to your metrics store.
    • Note that if you do not provision a metrics store, feast will only retain the latest metrics from your jobs.
  • Jaeger tracing for serving performance.
    • Set serving.jaeger.enabled to true, and configure the following parameters:
      • serving.jaeger.host
      • serving.jaeger.port
      • serving.jaeger.options.samplerType
      • serving.jaeger.options.samplerParam

Uninstalling Feast

To uninstall the feast deployment:

helm del feast
kubectl delete persistentvolumeclaim feast-postgresql
