⁠Quick reference

• Source: github.com/attune-io/attune⁠ (charts/attune)

⁠Install from Docker Hub

helm install attune oci://registry-1.docker.io/attuneio/attune-chart \
  --version 0.1.37 \
  --namespace attune-system --create-namespace

Tags are chart versions without a leading v, such as 0.1.37. The same chart is also published at oci://ghcr.io/attune-io/charts/attune, which is the path in the project install guide.

The chart installs ghcr.io/attune-io/attune with the chart appVersion as the tag. Chart 0.1.37 uses ghcr.io/attune-io/attune:0.1.37. It does not pull attuneio/attune unless you set image.repository.

⁠Requirements

• Kubernetes 1.32 or newer. On 1.32, enable the InPlacePodVerticalScaling feature gate. On 1.33–1.34 it is beta and on by default. On 1.35 and newer it is GA.
• Helm 3.16 or newer, or Helm 4.x
• Prometheus, for usage metrics
• cert-manager 1.12 or newer for webhook TLS. To skip it: --set webhooks.enabled=false

Chart 0.1.23 defaults to image tag 0.1.23, which was never published. If you install that chart, add --set image.tag=v0.1.23. Chart 0.1.24 and newer can omit that pin.
