Running docker scan <image> returns an error on ubuntu 20.04

当我尝试使用 docker scan hello-world 扫描本地图像(如 hello-world 图像)时,出现此错误

docker: 'scan' is not a docker command.
See 'docker --help'

有可用插件:

要求: 了解 docker-存储库

按照 https://docs.docker.com/engine/install/ubuntu/

中的安装指南,这应该已经完成

示例:

$ cat /etc/apt/sources.list.d/docker.list 
deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable

安装:

$ sudo apt update
$ sudo apt install docker-scan-plugin

运行 docker scan 将揭示更多要求:

  • 登录Docker Hub
  • 同意访问 Snyk (有关更多信息,请在网上搜索 docker Snyk。)
$ docker scan hello-world
