[Docker] Trouble shooting - Cannot mount the data volume

 Docker   Data volumes  

While mounting a host’s data volume to a container, I could not find the folder/files inside the folders.

$ ls /www/html

index.html

$ docker run -d -P -v "$(pwd)/www":/app:ro apache2-webserver /bin/bash

root@xxxx:/app# ls

root@xxxx:/app#

Here is my way to solve it,

1.  Change host’s absolute path to relative path

2.  Update the settings of VM to allow sharing certain drives or directories to Docker.

For example, in VM VirtualBox manager, find the Sharing folders and add the path.

After did so, it works like a charm.

$ ls /www/html

index.html

$ docker run -d -P -v "/www":/app:ro apache2-webserver /bin/bash

root@xxxx:/app# ls

html

root@xxxx:/app# ls html

index.html
