Docker List Volumes

Author:

In this guide, we will see how to list Docker volumes with examples.

The Importance of Listing Volumes

Inventory Management: Keep track of your volumes and their purposes. 

Data Management: Understand where your containerized applications are storing their persistent data.

Resource Optimization: Identify unused volumes that might be occupying crucial disk space. 

Listing All Docker Volumes

Basic Volume Listing: 

The simplest command to fetch a list of all your Docker volumes is:

docker volume ls

For example:

$ docker volume ls
DRIVER              VOLUME NAME
local               projectA_data
local               projectB_backup
local               nginx_config

The above output showcases three volumes (projectA_data, projectB_backup, and nginx_config) all using the default local driver.

Filtering Volume Listings: 

Docker provides capabilities to filter volume listings based on specific criteria. This feature is handy when dealing with a large number of volumes. 

To list volumes created with a specific driver:

docker volume ls -f driver=DRIVER_NAME

For example:

$ docker volume ls -f driver=local
DRIVER              VOLUME NAME
local               projectA_data
local               projectB_backup
local               nginx_config

Inspecting Volumes: 

For a more in-depth view of a particular volume:

$ docker volume inspect projectA_data
[
    {
        "CreatedAt": "2023-08-15T09:30:25Z",
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/projectA_data/_data",
        "Name": "projectA_data",
        "Options": {},
        "Scope": "local"
    }
]

This detailed view provides insights such as creation date, mount point on the host system, and other associated metadata.
