[docker] aufs

docker 2017. 10. 19. 21:46

docker info 커맨드를 실행하면 다음 스토리지 드라이버로 aufs가 나타난다.  


Storage Driver: aufs

 Root Dir: /var/lib/docker/aufs

 Backing Filesystem: extfs

 Dirs: 98

 Dirperm1 Supported: true

docker의 내부 스택이 바로 aufs로 되어 있다.

따라서 docker containerization을 지원하는 형태는 mesos는 지원하는 당연히 aufs 파일 시스템을 지원한다. 

ubuntu랑도 docker가 잘 궁합이 맞는 것도 그런 드 하다. 



The reason AUFS is introduced is because overlayfs support hasn’t been merged until kernel 3.18 and Docker’s default storage backend for ubuntu 14.04 is AUFS.

Like overlayfs, AUFS is also a unioned file system, which is very stable, has a lot of real-world deployments, and has strong community support.

Some Linux distributions do not support AUFS. This is usually because AUFS is not included in the mainline (upstream) Linux kernel.
