hi @KodeKloud / @mmumshad

This query is wrt to Q2 of Lab : Docker Storage & Volume .

I am not able to find the required directory name matching under path /var/lib/docker/container
Can you please guide ?

What folder under /var/lib/docker are the files related to the container alpine-3 image stored?

Have you did docker inspect ?

Which storage driver supports? docker info?

Hi @ppnehe

For more clarification check the solution below :

hi @KodeKloud

Thank you for your output .

I tried this lab today and I am getting desired output and checks are passing.

This time I can see when I do the $docker container ls -a I can really see atleast one container_ID starting with 6786.

Can you please identify and help me understand what was my mistake earlier attempt ?
When I did $docker container ls -a why I was not able to find atleast one right answer “container_id” one of the answers to choose from ?
