post_delete_hook

This hook runs when you do helm uninstall unless …

• you give –no-hooks to helm
• you set the enable flag to False at INSTALL time.

imageRegistry

Registry and Tag portion of Wallaroo images. Third party images are not included. Tag is
computed at runtime and overridden. In online Helm installs, these should not be touched; in
airgap Helm installs imageRegistry must be overridden to local registry.

generate_secrets

If true, generate random secrets for several services at install time.
If false, use the generic defaults listed here, which can also be overridden by caller.

assays

This is a (currently) Dashboard-specific feature flag to control the display of Assays.

custTlsSecretName

To provide TLS certificates, (1) set deploymentStage to “cust”, then (2) provide EITHER the
name of an existing Kubernetes TLS secret in custTlsSecret OR provide base64 encoded secrets
in custTlsCert and custTlsKey.

domainPrefix

DNS specification for our named external service endpoints.

To form URLs, we concatenate the optional domainPrefix, the service name in question, and then
the domainSuffix. Their values are based on license, type, and customer config inputs. They
MUST be overriden per install via helm values, or by Replicated.

Community – prefix/suffix in license

Enterprise et al – prefix/suffix from config

wallarooSecretName

In online Helm installs, an image pull secret is created and this is its name. The secret allows
the Kubernetes node to pull images from proxy.replicated.com. In airgap Helm installs, a local
Secret of type docker-registry must be created and this value set to its name.

privateModelRegistry

If the customer has specified a private model container registry, the enable flag will reflect
and the secret will be populated. registry, username, and password are mandatory. email
is optional. registry is of the form “hostname:port”.

apilb

Main ingress LB for Wallaroo services.

The Kubernetes Ingress object is not used, instead we deploy a single Envoy load balancer with a
single IP in all cases, which serves: TLS termination, authentication (JWT) checking, and both
host based and path based application routing. Customer should be aware of two values in particular.

api.serviceType defaults to ClusterIP. If api.serviceType is set to LoadBalancer, cloud
services will allocate a hosted LB service, in which case the apilb.annotations should be
provided, in order to pass configuration such as “internal” or “external” to the cloud service.

Example:
apilb:
serviceType: LoadBalancer
annotations: service.beta.kubernetes.io/aws-load-balancer-internal: “true”

keycloak

Wallaroo can connect to a variety of identity providers, broker OpenID Connect authentication
requests, and then limit access to endpoints. This section configures a https://www.keycloak.org
installation. If a provider is specified here, Keycloak will configure itself to use that on
install. If no providers are specified here, the administrator must login to the Keycloak
service as the administrative user and either add users by hand or create an auth provider. In
general, a client must be created upstream and a URL, client ID, and secret (token) for that
client is entered here.

dbcleaner

Manage retention for fluentbit table. This contains log message outputs from orchestration tasks.

plateau

Plateau is a low-profile fixed-footprint log processor / event store for fast storage of
inference results. The amount of disk space provisioned is adjustable. Smaller than “100Gi” is
not recommended for performance reasons.

pythonAPIServer

Model conversion is an optional service that allows converting non-onnx models (keras, sklearn,
and xgboost) to onnx and adding them to your pipeline, without extensive manual conversion or
processing steps. This allows more rapid iteration over models or experiments.

wsProxy

This controls the wsProxy, and should only be enabled if nats (ArbEx) is also enabled.
wsProxy is required for the Dashboard to subscribe to events and show notifications.

orchestration

Pipeline orchestration is general task execution service that allows users to upload arbitrary
code and have it executed on their behalf by the system. nats and arbex must be enabled.

models

The model server supports model autoconversion and requires nats and arbitrary execution to be
enabled.
