我一直在重读Docker文档,试图了解Docker和完整VM之间的区别.它如何设法提供完整的文件系统,隔离的网络环境等,而不是那么重？

为什么将软件部署到Docker映像(如果这是正确的术语)比简单地部署到一致的生产环境更容易？

我正在使用ApacheBench(ab)来测量Linux上两个nginx的性能.他们有相同的配置文件.唯一的区别是nginx在docker容器中运行.

主机系统上的Nginx:

Running: ab -n 50000 -c 1000 http://172.17.0.2:7082/

Concurrency Level:      1000

Docker容器中的Nginx:
