修正方法

Apply the following steps to reduce unnecessary service account token mounting in OKE: • Set automountServiceAccountToken to false for Pods and ServiceAccounts that do not require Kubernetes API access. This reduces unnecessary default token auto mounting. • Update workloads to use a dedicated serviceAccountName only where a service account token is operationally required, instead of inheriting token behavior from the namespace default service account. Each application should use its own dedicated service account. • For workloads that need OCI access, use OKE workload identity with a dedicated service account rather than broad default token mounting. OKE workload identity uses the combination of cluster, namespace, and service account to grant access to OCI resources for the intended workload.
