`mc anonymous set-json`

Syntax

The mc anonymous set-json command sets anonymous (i.e. unauthenticated or public) access policies for a bucket using using an IAM JSON policy document.

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

EXAMPLE

The following command applies the JSON-formatted anonymous policy to the mydata bucket on the myminio MinIO deployment:

mc anonymous set-json ~/mydata-anonymous.json myminio/mydata

SYNTAX

The command has the following syntax:

mc [GLOBALFLAGS] set-json POLICY 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

POLICY: Required The path to the JSON-formatted policy to assign to the specified ALIAS.

ALIAS

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

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-json public play/mybucket

Global Flags

This command supports any of the global flags.

Examples

Set Anonymous Policy for Bucket

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

mc anonymous set-json POLICY ALIAS/PATH

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

Remove Anonymous Policy for Bucket

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

mc anonymous set none ALIAS/PATH

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

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.
