Kubernetes Misconfiguration: Insecure Kubelet Transport

YAML

Abstract

已棄用的旗標將停用 Kubernetes API 伺服器與 Kubelet 之間的安全通訊。

Explanation

從 Kubernetes API 伺服器到 Kubelet 的連線，通常攜帶敏感資料，例如機密和指令。依預設，API 伺服器與 Kubelet 之間的連線會在傳輸過程中透過傳輸層安全性 (TLS) 進行保護。如果 --kubelet-https 旗標設定為 false，安全通訊將停用。

範例 1：以下組態將停用 API 伺服器與 Kubelet 之間的安全通訊，因為 API 伺服器是在 --kubelet-https 旗標設定為 false 的情況下啟動的。


...
spec:
  containers:
  - command:
    - kube-apiserver
    - --kublet-https=false
    - --authorization-mode=RBAC
    image: example.domain/kube-apiserver-amd64:v1.6.0
    ...
