Verify node auto-upgrade is enabled for GKE node pools

How it is checked

Audit method: Shell command

out=$(gcloud container node-pools list --cluster "${GKE_CLUSTER:?set GKE_CLUSTER}" --location "${GKE_LOCATION:?set GKE_LOCATION}" ${GKE_PROJECT:+--project=$GKE_PROJECT} --format='value(name,management.autoUpgrade)') || exit 1
bad=$(printf '%s\n' "$out" | awk -F '\t' 'NF && !($2=="True") {print $1 ": " $2}')
if [ -z "$bad" ]; then echo compliant; else printf '%s\n' "$bad"; fi

Expected output

compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Enable node auto-upgrade for any GKE node pool where the audit result is not true. This allows GKE to automatically schedule eligible node pools for upgrades when upgrade targets become available, subject to maintenance windows, maintenance exclusions, release channel behavior, and upgrade rollout constraints. gcloud container node-pools update $POOL_NAME \ --cluster $CLUSTER_NAME \ --location $LOCATION \ --project $PROJECT_ID \ --enable-autoupgrade After remediation, rerun the audit command and confirm that management.autoUpgrade returns true. If multiple node pools are present, repeat the audit and remediation for each applicable node pool.
