`mc share download`

Syntax

The mc share download command generates a temporary presigned URL with integrated access credentials for downloading objects from a MinIO bucket. The temporary URL expires after a configurable time limit.

Applications can perform a GET to retrieve the object from the URL.
Users can open the URL in a browser to download the object.

For more information on shareable object URLs, see the Amazon S3 documentation on Pre-Signed URLs.

EXAMPLE

The following command generates a new presigned download URL for the mydata bucket on the myminio MinIO deployment:

mc share download --recursive myminio/mydata

SYNTAX

The command has the following syntax:

mc [GLOBALFLAGS] share download           \
                 [--expire "string"]      \
                 [--recursive]            \
                 [--version-id "string"]  \
                 ALIAS

Brackets [] indicate optional parameters.
Parameters sharing a line are mutually dependent.
Parameters separated using the pipe | operator are mutually exclusive.

Copy the example to a text editor and modify as-needed before running the command in the terminal/shell.

Parameters

ALIAS

Required

The alias of a MinIO deplyment and the full path to the object for which to generate a download URL. For example:

mc share download play/mybucket/object.txt

You can specify multiple objects on the same or different MinIO deployments. For example:

mc share download play/mybucket/object.txt play/mybucket/otherobject.txt

If specifying the path to a bucket or bucket prefix, you must also specify the --recursive argument. For example:

mc share download --recursive play/mybucket/

mc share download --recursive play/mybucket/myprefix/

--expire, E

Optional

Set the expiration time limit for all generated URLs.

Specify a string with format ##h##m##s format. For example: 12h34m56s for an expiry of 12 hours, 34 minutes, and 56 seconds after URL generation.

Defaults to 168h or 168 hours (7 days).

--recursive, r

Optional

Recursively generate URLs for all objects in a mc share download ALIAS bucket or bucket prefix.

Required if any ALIAS specifies a path to a bucket or bucket prefix.

--version-id, vid

Optional

Directs mc share download to operate only on the specified object version.

--version-id requires that the specified ALIAS be an S3-compatible service that supports Bucket Versioning. For MinIO deployments, use mc version to enable or disable bucket versioning.

Global Flags

This command supports any of the global flags.

Examples

Generate a URL to Download Object(s)

Get Specific Object

Use mc share download to generate a URL that supports GET requests for an object:

mc share download --expire DURATION ALIAS/PATH

Replace ALIAS with the alias of the MinIO deployment.
Replace PATH with the path to the object on the MinIO deployment.
Replace DURATION with the duration after which the URL expires. For example, to set a 30 day expiry, specify 30d.

Get Object(s) in a Bucket

Use mc share download with the --recursive option to generate a URL for each object in a bucket. Each URL supports GET requests for its associated object:

mc share download --recursive --expire DURATION ALIAS/PATH

Replace ALIAS with the alias of the MinIO deployment.
Replace PATH with the path to the bucket or bucket prefix on the MinIO deployment.
Replace DURATION with the duration after which the URL expires. For example, to set a 30 day expiry, specify 30d.

Behavior

S3 Compatibility

The mc commandline tool is built for compatibility with the AWS S3 API and is tested with MinIO and AWS S3 for expected functionality and behavior.

MinIO provides no guarantees for other S3-compatible services, as their S3 API implementation is unknown and therefore unsupported. While mc commands may work as documented, any such usage is at your own risk.
