如何检查docker映像依赖于什么操作系统?

docker run <image-name> /etc/*release*

它将返回有关图像的元数据。

See example output here

在docker世界中,你或多或少会遇到像Alpine这样的操作系统。 因此,最明智的做法是获取 /etc/os-release 在大多数情况下都会出现的文件。

# Tomcat 9 running on Alpine OS
docker run -it tomcat:9-alpine cat /etc/os-release

# Tomcat 9 running Debian (buster)
docker run -it tomcat:9 cat /etc/os-release

事实上,你的Jenkins是在Ubuntu 64位、Fedora 24或Debian jessie上构建的,这不应该困扰你,因为它无论如何都应该可以工作。
