mc anonymous set
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:
The command has the following syntax:
mc [GLOBALFLAGS] policy set PERMISSION ALIAS

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.
