Install options

Each installer option, the supported versions and the namespaces.

The Kind installer#

The script is scripts/kind/setup-sentinel.sh. It always installs the core components. Each other component has an option.

The core components#

cert-manager, the Gateway API resources, the Istio gateway controller, Keycloak, the operator and the webhook.

The component options#

Option What it adds What it also enables
--with-istio The Istio ambient mesh: mTLS and waypoints —
--with-spire SPIRE and the SPIFFE identity provider —
--with-backend The Sentinel backend —
--with-ui The console --with-backend
--with-mcp-gateway The MCP Gateway —
--with-kuadrant The Kuadrant operator --with-mcp-gateway
--with-otel The OpenTelemetry collector —
--with-mlflow MLflow --with-otel, --with-istio
--with-builds Tekton and Shipwright —
--with-kiali Kiali and Prometheus --with-istio
--with-skills The skills flags and a skill store in the cluster --with-backend, --with-ui
--with-examples The weather agent and the weather tool —
--with-all Each option above —

The other options#

Option Function
--skip-cluster Uses a Kind cluster that exists.
--build-images Builds the platform images from source and copies them into Kind.
--preload-images Downloads the third-party images first, then copies them into the node. This option avoids the rate limits of Docker Hub.
--secrets-file FILE Names a file of secrets. The default is charts/sentinel/.secrets.yaml, when that file exists.
--cluster-name NAME Names the Kind cluster. The default is sentinel.
--domain DOMAIN Sets the domain for each address. The default is localtest.me.
--sentinel-values FILE A Helm values file for the sentinel chart.
--sentinel-deps-values FILE A Helm values file for the sentinel-deps chart.
--dry-run Prints each command. It makes no change.

The script gives the --sentinel-values file to Helm as --values. Each valid Helm value is therefore accepted.

For the current list, run scripts/kind/setup-sentinel.sh --help.

The OpenShift installer#

The script is scripts/ocp/setup-sentinel.sh.

Option Function
--sentinel-repo PATH\|URL A local directory or a GitHub address. The default action is a clone of main into ~/.cache/sentinel.
--realm REALM The Keycloak realm. The default is sentinel.
--skip-ovn-patch Omits the OVN routing change.
--skip-mcp-gateway Omits the MCP Gateway.
--skip-ui Omits the console and the backend.
--skip-mlflow Omits MLflow.
--operator-image IMG:TAG Uses a different operator image.
--dry-run Prints each command. It makes no change.

Remove an installation#

scripts/kind/cleanup-sentinel.sh                    # Remove Sentinel. Keep the cluster.
scripts/kind/cleanup-sentinel.sh --destroy-cluster  # Remove both.

The feature flags#

Set each flag in the Helm values, during the installation or with the --reuse-values option.

Flag What it controls
featureFlags.skills Import, list and delete a skill, and give a skill to an agent.
featureFlags.externalSkills References to an external skill registry. It needs skills also.
components.skillberryStore.enabled Installs the skill store in the cluster.
ui.backend.contextServiceUrl Enables agent context. An empty value disables it.
meshSelfHeal.enabled For Kind only. Adds a CronJob that restarts the data plane after a certificate expires.

The sentinel-feature-gates ConfigMap is separate. It applies to the whole cluster. It controls which Cortex components run, and whether skill discovery is active. A namespace cannot replace it, and a workload cannot replace it. See Custom resources.

The supported versions#

The tools#

Tool Version
kubectl 1.32.1 or later
Helm 3.18.0 or later, below 4
git 2.48.0 or later
Ollama 0.11.0 or later, when you use it
oc 4.16.0 or later, for OpenShift

The platforms#

Platform Status
Kubernetes on Kind The primary target for development. The test pipeline uses version 1.35.0.
OpenShift The project tested version 4.19. The test pipeline uses version 4.20 with HyperShift.
Another Kubernetes distribution It must operate with Helm. The test pipeline does not cover it.

For the state of each test pipeline, see the repository README.

The machine size#

Profile Memory CPUs What operates
Recommended 18 GiB 6 The ambient mesh, SPIRE, the console, the backend and a build from source.
Minimum 16 GiB 4 The core platform and the console. Images only.
Below the minimum — 4 or fewer The installation usually completes. A build stays in Pending.

The installer gives a warning below the recommended values. It does not stop.

The namespaces#

Namespace Contents
sentinel-system The operator, the webhook, the backend, the console and MLflow
