11. Docker is more than LXC
● AUFS - Another Union File System,相當於把 Host
(Server) 的目錄當成 Guest (Container) 的 Disk。
● Base Image - 透過 base image,可以在 Docker上執行各種
的 Distribution Linux 而不受限於 Host 的 OS 種類,Image
裡面其實就是一堆必要檔案的集合。
16. Docker 術語 - Image
A Docker image is a read-only template.
● 唯讀的映像檔
● 相當於 VM 的樣板機
● 不可變更的 (immutable)
17. Docker 術語 - Container

application to run. Each container is created from a Docker
image.
● 以 Image 為基板,放到記憶體中執行的
● Docker 執行起來的最小單位
● Container 裡面必須有一個前景 (foreground) 執行的程式
