使用 docker inspect 命令查看容器掛載的volume的目錄html

$ sudo docker inspect --format "{{.Volumes}}" redis-master

Template parsing error: template: :1:2: executing "" at <.Volume>: map has no entry for key "Volumes"

結果返回錯誤，說<.Volumes>爲key的map不存在。redis

　　上網查了查，發現有人說這是版本問題，並找到另外一種方法，代碼以下docker

$ sudo docker inspect --format "{{.Config.Volumes}}" redis-master

map[/data:{}]

此次結果卻是返回了map[/data:{}]，可是並無獲取到volume掛載在宿主機上的地址。又查了查，獲得另外一種方法，代碼以下json

ubuntu@ip-172-31-18-10:/etc$ sudo docker inspect redis-master | grep Mount -A 20

返回結果以下：ubuntu
