Andrea Longo 0747c9a191 mention that tiny files are not compressed, also other typos (#1357) 
Came up in a customer issue. Specifically the threshold is 4 kb and
there is no configuration option. (Nor does Klaus want one.)

Worth adding? With how much detail? The threshold choice is because of
typical block size on disk. You will use at least that much anyway so
why bother compressing.

Drive-by fix tacked onto this PR: correct typos in some `mc anonymous`
examples.

mc anonymous set

minio

Table of Contents

mc anonymous set

Syntax

The mc anonymous set command sets anonymous (i.e. unauthenticated or public) access policies <minio-policy> for a bucket.

Buckets with anonymous policies allow clients to access the bucket contents and perform actions consistent with the specified policy without authentication <minio-authentication-and-identity-management>.

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

EXAMPLE

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.

SYNTAX

The command has the following syntax:

mc [GLOBALFLAGS] policy set PERMISSION ALIAS

Parameters

PERMISSION

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

Required The full path to the bucket or bucket prefix to which the command applies the specified ~mc anonymous set PERMISSION.

Specify the alias <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

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 <mc anonymous set PERMISSION> with a supported permission <mc anonymous set PERMISSION>.
  • Replace ALIAS <mc anonymous set ALIAS> with the alias <mc alias> of a configured S3-compatible host.
  • Replace PATH <mc anonymous set ALIAS> with the destination bucket.
