Docker 数据卷查看 映射的目录出错(Template parsing error: template: :1:2: executing "" at <.Volumes>: map has no)

报错：

[root@ops-ip-statistic ~]# docker inspect -f {{.Volumes}} volume-test1

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

解决：

1，使用 “.Config.Volumes” 替换 “.Volumes”

[root@ops-ip-statistic ~]# docker inspect -f {{.Config.Volumes}} volume-test1
map[/data:{}]

显示为空，此法 在此不可行

2，直接看容器的所有信息 再grep

[root@ops-ip-statistic _data]# docker inspect volume-test1 | grep Mounts -A 10
"Mounts": [
{
"Name": "0a3d70900bd0fa46c797f7aa7ff5176b7f6a5a798b6a282cd6c532facfd24925",
"Source": "/var/lib/docker/volumes/0a3d70900bd0fa46c797f7aa7ff5176b7f6a5a798b6a282cd6c532facfd24925/_data",
"Destination": "/data",
"Driver": "local",
"Mode": "",
"RW": true,
"Propagation": ""
}
],

找到对应的目录是：

/var/lib/docker/volumes/0a3d70900bd0fa46c797f7aa7ff5176b7f6a5a798b6a282cd6c532facfd24925/_data

进入容器中创建一个文件：

[root@nginx data]# echo 123 >a
[root@nginx data]# cat a
123

在宿主机的对应的目录中查看：

[root@ops-ip-statistic _data]# cd /var/lib/docker/volumes/0a3d70900bd0fa46c797f7aa7ff5176b7f6a5a798b6a282cd6c532facfd24925/_data
[root@ops-ip-statistic _data]# cat a
123

可行！
