v1.0.x

在 Kubernetes 集群中部署 KubeCube

⚠️修改 Kubernetes API-Server 配置

必要性

  1. KubeCube 对多集群提供统一的认证和鉴权服务，需要使用 k8s api-server 的 auth-webhook 能力来做拓展。

  2. KubeCube 提供对 k8s-apiserver 日志进行审计的能力，这需要为 k8s api-server 指定审计服务后端。

修改操作

如果您的 k8s api-server 服务是以 deployment 形式运行的，请直接修改 deployment ；如果您的 k8s api-server 服务是以 static pod 形式运行的，您需要修改对应的 manifest 文件，它的文件路径通常为 /etc/kubernetes/manifests/kube-apiserver.yaml ，修改内容如下：

  1. apiVersion: v1
  2. kind: Pod
  3. metadata:
  4.   name: kube-apiserver
  5.   namespace: kube-system
  6. spec:
  7.   containers:
  8.     - command:
  9.         - kube-apiserver
  10.         - --audit-log-format=json
  11.         - --audit-log-maxage=10
  12.         - --audit-log-maxbackup=10
  13.         - --audit-log-maxsize=100
  14.         - --audit-log-path=/var/log/audit
  15.         - --audit-policy-file=/etc/cube/audit/audit-policy.yaml
  16.         - --audit-webhook-config-file=/etc/cube/audit/audit-webhook.config
  17.         - --authentication-token-webhook-config-file=/etc/cube/warden/webhook.config
  18.       name: kube-apiserver
  19.       volumeMounts:
  20.         - mountPath: /var/log/audit
  21.           name: audit-log
  22.         - mountPath: /etc/cube
  23.           name: cube
  24.           readOnly: true
  25.   volumes:
  26.     - hostPath:
  27.         path: /var/log/audit
  28.         type: DirectoryOrCreate
  29.       name: audit-log
  30.     - hostPath:
  31.         path: /etc/cube
  32.         type: DirectoryOrCreate
  33.       name: cube
