k8s物料清单工具——KubeClarity

介绍

KubeClarity是一个用于检测和管理容器镜像和文件系统的软件清单（SBOM）和漏洞的工具。它扫描运行时的K8s集群和CI/CD流水线，以增强软件供应链安全性。

安装

添加 helm 仓库

bash 复制代码

helm repo add kubeclarity https://openclarity.github.io/kubeclarity

部署

bash 复制代码

helm install --create-namespace kubeclarity kubeclarity/kubeclarity -n kubeclarity

配置

kubeclarity 有一个配置文件，配置文件中记录了对整个 Kubernetes 集群扫描时所需要的 Job，内容如下：

使用

kubeclarity 的界面主要分为 Dashboard、Applications、Applications Resources、Package、Vulnerability 和 Scan 界面，用户唯一能操作的地方就是在 Scan 界面中点击扫描或者配置定时扫描任务。下面就为各个板块的截图：
