Docker學習(6)------配置Docker使用overlay

操作環境

Centos 7 Docker version 17.03.0-ce, build 60ccb22

操作步驟

1.配置Docker儲存方式為overlay,儲存目錄為/mnt,修改docker.service配置檔案中的ExecStart引數如下
# for containers run by docker
ExecStart=/usr/bin/dockerd --graph=/mnt --storage-driver=overlay

2.重啟docker service
[[email protected] /]# systemctl daemon-reload 
[[email protected]
/]# systemctl restart docker

3.檢視Docker資訊,可以檢視到Storage Driver為overlay,Docker Root Dir為 /mnt
[[email protected] /]# docker info
