`mc mb`

Syntax

The mc mb command creates a new bucket or directory at the specified path.

You can also use mc mb against the local filesystem to produce similar results to the mkdir -p commandline tool.

EXAMPLE

The following command creates a new bucket mydata on the myminio MinIO deployment. The command creates the bucket with object locking enabled.

mc mb --with-locks myminio/mydata

SYNTAX

The command has the following syntax:

mc [GLOBALFLAGS] mb                   \
                 [--ignore-existing]  \
                 [--region "string"]  \
                 [--with-lock]        \
                 [--with-versioning]  \
                 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

ALIAS

Required

The MinIO or other S3-compatible service on which to create the new bucket.

For creating a bucket on MinIO, specify the alias and the name of the bucket. For example:

mc mb play/mybucket

For creating a directory on a local filesystem, specify the full path to that directory. For example:

mc mb ~/mydata/mydir

--ignore-existing, p: Optional
Directs mc mb to do nothing if the bucket or directory already exists.

--region

Optional

The region in which to create the specified bucket. Has no effect if the specified ALIAS is a filesystem directory.

If not specified, default value is us-east-1.

--with-lock, l: Optional
Enables object locking on the specified bucket. Object locking requires, and therefore implies, enabling object versioning.

Important

You can only enable object locking when creating the bucket. Buckets created without object locking cannot use Bucket Lifecycle Management or Bucket Object Locking functionality.

--with-versioning

Optional

Enables object versioning on the new bucket. With versioning enabled, by default MinIO allows up to the maximum value of an Int64 versions per object, or over 9.2 quintillion. Define object expiration rules to remove versions of objects no longer needed, such as by the number of versions or the date of versions.

Versioning is required for bucket replication or site replication. Versioning does not imply or require object locking.

Global Flags

This command supports any of the global flags.

Examples

Create Bucket with Object Locking

Use mc mb to create a bucket on an S3-compatible host. The --with-lock option creates the bucket with locking enabled:

mc mb --with-lock ALIAS/BUCKET

Replace ALIAS with the alias of the S3-compatible host.
Replace BUCKET with the bucket to create.

Create a New Bucket in a Specific Region

Use mc mb to create a bucket on an S3-compatible host. The --region option creates the bucket in a desired region.

mc mb --region --region=us-west-2 myminio/mynewbucket

The above command creates a new bucket, mynewbucket on the myminio bucket within the us-west-2 region.

Create a New Bucket with Versioning Enabled

mc mb --with-versioning myminio/myversionedbucket

The above command creates a new bucket, myversionedbucket, on the myminio alias. The new bucket enables object versioning for all objects in the bucket.
