Quick Start

The shortest path from an empty Kubernetes cluster to a running SkyWalking install: OAP 11.0.0 with Elasticsearch storage and Horizon UI 1.0.0, reachable in your browser.

Before you start

A Kubernetes cluster and a working kubectl context.
Helm 3.8 or newer (the OCI install below needs a Helm that can pull oci:// charts).
oap.storageType has no default and must be set, but elasticsearch.enabled defaults to true, so the chart deploys Elasticsearch through ECK as a 3-node cluster (elasticsearch.nodeSets[0].count: 3, elasticsearch.version: 8.18.8). See Requirements for sizing, and Pick a Storage Backend if you would rather start with BanyanDB.

1. Set the release variables

export SKYWALKING_RELEASE_VERSION=5.0.0
export SKYWALKING_RELEASE_NAME=skywalking
export SKYWALKING_RELEASE_NAMESPACE=default

2. Install the ECK CRDs

Helm renders the chart's Elasticsearch custom resource during install, so the ECK CRDs must already exist in the cluster. Install them as their own release — the version matches the eck-operator dependency pinned in chart/skywalking/Chart.yaml:

helm install eck-crds eck-operator-crds \
  --repo https://helm.elastic.co --version 3.3.1 \
  -n "${SKYWALKING_RELEASE_NAMESPACE}" --create-namespace

Then pass --set eck-operator.installCRDs=false when installing SkyWalking so the two releases do not both own the CRDs.

Skip this step entirely if you set elasticsearch.enabled=false — using an external Elasticsearch, BanyanDB, or PostgreSQL needs no CRDs.

3. Install the chart

helm install "${SKYWALKING_RELEASE_NAME}" \
  oci://docker.io/apache/skywalking-helm \
  --version "${SKYWALKING_RELEASE_VERSION}" \
  -n "${SKYWALKING_RELEASE_NAMESPACE}" --create-namespace \
  --set oap.image.tag=11.0.0 \
  --set oap.storageType=elasticsearch \
  --set ui.image.tag=horizon-1.0.0 \
  --set eck-operator.installCRDs=false

The three values that have no default and must always be set:

value	this install	notes
`oap.image.tag`	`11.0.0`	OAP server image tag
`oap.storageType`	`elasticsearch`	also `banyandb`, `postgresql`
`ui.image.tag`	`horizon-1.0.0`	must be a `horizon-*` tag

Other chart sources — Apache JFrog, ghcr.io snapshots, a local clone — are covered in Where to Get the Chart.

4. Wait for it to come up

kubectl get pods -n "${SKYWALKING_RELEASE_NAMESPACE}" -w

A one-shot *-oap-init-* Job creates the storage schema; the OAP Deployment runs in -Dmode=no-init and stays un-Ready until that Job finishes. Both run in the main install phase, so you can add --wait --wait-for-jobs to the helm install above and let Helm block instead (the extra --wait-for-jobs makes Helm surface an init-Job failure directly). To watch the Job:

kubectl get job -n "${SKYWALKING_RELEASE_NAMESPACE}" -l release="${SKYWALKING_RELEASE_NAME}"
kubectl logs -n "${SKYWALKING_RELEASE_NAMESPACE}" job/<oap-init-job-name> -f

Details in The OAP Init Job; failures in Install and Startup Failures.

5. Reach the UI

The UI Service is ClusterIP on port 80 (targeting the BFF's port 8081). Its name is <release>-skywalking-helm-ui, because the chart is named skywalking-helm:

kubectl port-forward -n "${SKYWALKING_RELEASE_NAMESPACE}" \
  svc/${SKYWALKING_RELEASE_NAME}-skywalking-helm-ui 8080:80
open http://127.0.0.1:8080

Prefer shorter resource names? Add --set fullnameOverride=skywalking at install time and the Service becomes skywalking-ui.

For a NodePort, LoadBalancer or Ingress instead of port-forwarding, see UI Service and Ingress.

6. Create a login — the install has none

Horizon UI has no built-in admin/admin account, and this chart configures no users. The BFF does not fail closed: it boots, serves the login page, and passes its readiness probe, so the pod reports Ready and nobody can log in.

Go to Set Up Logins for a copy-pastable demo user and the production Secret-backed pattern. Do this before you rely on the deployment.

Uninstall

helm uninstall "${SKYWALKING_RELEASE_NAME}" -n "${SKYWALKING_RELEASE_NAMESPACE}"
helm uninstall eck-crds -n "${SKYWALKING_RELEASE_NAMESPACE}"
