Release v0.1.0-rc.12

CRE v0.1.0-rc.12

The Cluster Readiness Engine (CRE) is a Kubernetes controller that
certifies GPU clusters before production use. It runs real training
and communication workloads across topology-aware node groups,
measures goodput and bandwidth, detects hardware failures, and
quarantines bad nodes. See the
README
for the full feature list.

Install nvcrectl

While this repository is internal, GitHub serves release assets only through
authenticated API downloads — plain curl against releases/download/...
returns a 404 "Not Found" page instead of the script, even with a token.
Fetch the installer with the gh CLI (authenticate with gh auth login):

gh release download v0.1.0-rc.12 \
  --repo NVIDIA/cluster-readiness-engine \
  --pattern installer --output - | bash -s -- -v v0.1.0-rc.12

Once the repository is public, the plain curl form works. The version is
named explicitly because releases/latest resolves only to the newest
stable release, and every release so far is a pre-release. Once v0.1.0
is tagged, the shorter form installs the newest stable one:

curl -sSL https://github.com/NVIDIA/cluster-readiness-engine/releases/download/v0.1.0-rc.12/installer | bash -s -- -v v0.1.0-rc.12
curl -sSL https://github.com/NVIDIA/cluster-readiness-engine/releases/latest/download/installer | bash

Helm Chart

helm install cluster-readiness-engine \
  oci://ghcr.io/nvidia \
  --version v0.1.0-rc.12 \
  --namespace cluster-readiness-engine \
  --create-namespace

The controller image for this release is
