mc anonymous set

Syntax

The mc anonymous set command sets anonymous (i.e. unauthenticated or public) access policies for a bucket.

Buckets with anonymous policies allow clients to access the bucket contents and perform actions consistent with the specified policy without authentication.

To set anonymous bucket policies using an IAM JSON policy, use the mc anonymous set-json command.

The following command sets anonymous access policies for several buckets on the myminio MinIO deployment:

mc anonymous set upload myminio/uploads
mc anonymous set download myminio/downloads
mc anonymous set public myminio/public

Applications can perform the following operations without authentication:

PUT objects to myminio/uploads and myminio/public.
GET objects from myminio/downloads and myminio/public.

The command has the following syntax:

mc [GLOBALFLAGS] policy set PERMISSION 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

`PERMISSION`

mc-cmd

Required Name of the policy to assign to the specified ALIAS. Specify one of the following values:

none - Disable anonymous access to the ALIAS.
download - Enable download-only access to the ALIAS.
upload - Enable upload-only access to the ALIAS.
public - Enable download and upload access to the ALIAS.

`ALIAS`

mc-cmd

Required The full path to the bucket or bucket prefix to which the command applies the specified PERMISSION.

Specify the alias of the MinIO or other S3-compatible service and the full path to the bucket or bucket prefix. For example:

mc anonymous set public play/mybucket

Specify a bucket prefix to set the policy on only that prefix. For example, this command sets distinct anonymous bucket policies on the mybucket/downloads and mybucket/uploads prefixes:

mc anonymous set download play/mybucket/downloads
mc anonymous set upload play/mybucket/uploads

Global Flags

This command supports any of the global flags.

Examples

Set Anonymous Policy for Bucket

Use mc anonymous set to set the anonymous policy for a bucket:

mc anonymous set POLICY ALIAS/PATH

Replace POLICY with a supported permission.
Replace ALIAS with the alias of a configured S3-compatible host.
Replace PATH with the destination bucket.

Behavior

S3 Compatibility

SILO is the supported server for PGSTY mcli; compatibility with upstream MinIO and other S3 services is best effort.
