mc policy get-json

Syntax

The mc policy get-json command gets 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.

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

mc policy get-json myminio/mydata

The command has the following syntax:

mc [GLOBALFLAGS] get-json ALIAS
  • Brackets [] indicate optional parameters.

  • Parameters sharing a line are mutually dependent.

  • Parameters seperated 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 full path to the bucket or bucket prefix for which to get the anonymous bucket 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 get-json public play/mybucket

Global Flags

--debug
Optional

Enables verbose output to the console.

For example:

mc --debug COMMAND
--config-dir
Optional

The path to a JSON formatted configuration file that mc uses for storing data. See Configuration File for more information on how mc uses the configuration file.

--JSON
Optional

Enables JSON lines formatted output to the console.

For example:

mc --JSON COMMAND
--no-color
Optional

Disables the built-in color theme for console output. Useful for dumb terminals.

--quiet
Optional

Suppresses console output.

--insecure
Optional

Disables TLS/SSL certificate verification. Allows TLS connectivity to servers with invalid certificates. Exercise caution when using this option against untrusted S3 hosts.

--version
Optional

Displays the current version of mc.

--help
Optional

Displays a summary of command usage on the terminal.

Examples

Get Anonymous Policy for Bucket

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

mc policy get-json 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 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.
