Explore Volumes

Table of contents

The Volumes view in Docker Dashboard lets you create, delete, and perform other actions on your volumes. You can also see which volumes are being used as well as inspect the files and folders in your volumes.

View your volumes

You can view the following information about your volumes:

  • Name: The name of the volume.
  • Status: Whether the volume is in-use by a container or not.
  • Created: How long ago the volume was created.
  • Size: The size of the volume.
  • Scheduled exports: Whether a scheduled export is active or not.

By default, the Volumes view displays a list of all the volumes.

You can filter and sort volumes as well as modify which columns are displayed by doing the following:

  • Filter volumes by name: Use the Search field.
  • Filter volumes by status: To the right of the search bar, filter volumes by In use or Unused.
  • Sort volumes: Select a column name to sort the volumes.
  • Customize columns: To the right of the search bar, choose what volume information to display.

Create a volume

You use the following steps to create an empty volume. Alternatively, if you start a container with a volume that doesn't yet exist, Docker creates the volume for you.

To create a volume:

  1. In the Volumes view, select the Create button.
  2. In the New Volume modal, specify a volume name, and then select Create.

To use the volume with a container, see Use volumes.

Inspect a volume

To explore the details of a specific volume, select a volume from the list. This opens the detailed view.

The Container in-use tab displays the name of the container using the volume, the image name, the port number used by the container, and the target. A target is a path inside a container that gives access to the files in the volume.

The Stored data tab displays the files and folders in the volume and the file size. To save a file or a folder, right-click on the file or folder to display the options menu, select Save as..., and then specify a location to download the file.

To delete a file or a folder from the volume, right-click on the file or folder to display the options menu, select Delete, and then select Delete again to confirm.

The Exports tab lets you export the volume.

Clone a volume

Cloning a volume creates a new volume with a copy of all of the data from the cloned volume. When cloning a volume used by one or more running containers, the containers are temporarily stopped while Docker clones the data, and then restarted when the cloning process is completed.

To clone a volume:

  1. Sign in to Docker Desktop. You must be signed in to clone a volume.
  2. In the Volumes view, select the Clone icon in the Actions column for the volume you want to clone.
  3. In the Clone a volume modal, specify a Volume name, and then select Clone.

Delete one or more volumes

Deleting a volume deletes the volume and all its data. When a container is using a volume, you can't delete the volume, even if the container is stopped. You must first stop and remove any containers using the volume before you can delete the volume.

To delete a volume:

  1. In the Volumes view, select Delete icon in the Actions column for the volume you want to delete.
  2. In the Delete volume? modal, select Delete forever.

To delete multiple volumes:

  1. In the Volumes view, select the checkbox next to all the volumes you want to delete.
  2. Select Delete.
  3. In the Delete volumes? modal, select Delete forever.

Empty a volume

Emptying a volume deletes all a volume's data, but doesn't delete the volume. When emptying a volume used by one or more running containers, the containers are temporarily stopped while Docker empties the data, and then restarted when the emptying process is completed.

To empty a volume:

  1. Sign in to Docker Desktop. You must be signed in to empty a volume.
  2. In the Volumes view, select the volume you want to empty.
  3. Next to Import, select the More volume actions icon, and then select Empty volume.
  4. In the Empty a volume? modal, select Empty.

Export a volume

Beta feature

The export volume feature is currently in Beta.

You can export the content of a volume to a local file, a local image, an to an image in Docker Hub, or to a supported cloud provider. When exporting content from a volume used by one or more running containers, the containers are temporarily stopped while Docker exports the content, and then restarted when the export process is completed.

You can either export a volume now or schedule a recurring export.

Export a volume now

  1. Sign in to Docker Desktop. You must be signed in to export a volume.

  2. In the Volumes view, select the volume you want to export.

  3. Select the Exports tab.

  4. Select Quick export.

  5. Select whether to export the volume to Local or Hub storage or External cloud storage, then specify the following additional details depending on your selection.

Import a volume

You can import a local file, a local image, or an image from Docker Hub. Any existing data in the volume is replaced by the imported content. When importing content to a volume used by one or more running containers, the containers are temporarily stopped while Docker imports the content, and then restarted when the import process is completed.

To import a volume:

  1. Sign in to Docker Desktop. You must be signed in to import a volume.

  2. Optionally, create a new volume to import the content into.

  3. Select the volume you want to import content in to.

  4. Select Import.
