cluster-proportional-autoscaler

Chainguard's redistribution of the cluster-proportional-autoscaler Helm chart, pre-configured with hardened Chainguard Images.

Prerequisites

Authentication is required. First, authenticate with Chainguard:

chainctl auth login
chainctl auth configure-docker --pull-token --save
helm registry login cgr.dev

Create an image pull secret:

kubectl create secret docker-registry cgr-pull-secret \
  --docker-server=cgr.dev \
  --docker-username="$(echo cgr.dev | docker-credential-cgr get | jq -r '.Username')" \
  --docker-password="$(echo cgr.dev | docker-credential-cgr get | jq -r '.Secret')" \
  --namespace cluster-proportional-autoscaler

Installation

The chart requires an options.target (the workload it scales) and a config.linear (or config.ladder) block to render. Set both when installing:

helm install cluster-proportional-autoscaler \
  oci://cgr.dev/ORGANIZATION/charts/cluster-proportional-autoscaler \
  --namespace cluster-proportional-autoscaler \
  --create-namespace \
  --set imagePullSecrets[0].name=cgr-pull-secret \
  --set options.target="deployment/coredns" \
  --set config.linear.coresPerReplica=256 \
  --set config.linear.nodesPerReplica=16 \
  --set config.linear.min=1
