Minio Client Quickstart Guide

Minio Client (mc) provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff, find etc. It supports filesystems and Amazon S3 compatible cloud storage service (AWS Signature v2 and v4).

ls       List files and folders.
mb       Make a bucket or a folder.
cat      Display file and object contents.
pipe     Redirect STDIN to an object or file or STDOUT.
share    Generate URL for sharing.
cp       Copy files and objects.
mirror   Mirror buckets and folders.
find     Finds files which match the given set of parameters.
stat     Stat contents of objects and folders.
diff     List objects with size difference or missing between two folders or buckets.
rm       Remove files and objects.
events   Manage object notifications.
watch    Watch for file and object events.
policy   Manage anonymous access to objects.
session  Manage saved sessions for cp command.
config   Manage mc configuration file.
update   Check for a new software update.
version  Print version info.

Docker Container

Stable

docker pull minio/mc
docker run minio/mc ls play

Edge

docker pull minio/mc:edge
docker run minio/mc:edge ls play

Note: Above examples run mc against Minio play environment by default. To run mc against other S3 compatible servers, start the container this way:

docker run -it --entrypoint=/bin/sh minio/mc

then use the mc config command.

Install from Source

Source installation is intended only for developers and advanced users. mc update command does not support update notifications for source based installations. Please download official releases from https://minio.io/downloads/#minio-client.

If you do not have a working Golang environment, please follow How to install Golang.

go get -d github.com/minio/mc
cd ${GOPATH}/src/github.com/minio/mc
make

Add a Cloud Storage Service

If you are planning to use mc only on POSIX compatible filesystems, you may skip this step and proceed to everyday use.

To add one or more Amazon S3 compatible hosts, please follow the instructions below. mc stores all its configuration information in ~/.mc/config.json file.

mc config host add <ALIAS> <YOUR-S3-ENDPOINT> <YOUR-ACCESS-KEY> <YOUR-SECRET-KEY> --api <API-SIGNATURE> --lookup <BUCKET-LOOKUP-TYPE>

Alias is simply a short name to your cloud storage service. S3 end-point, access and secret keys are supplied by your cloud storage provider. API signature is an optional argument. By default, it is set to "S3v4".

Lookup is an optional argument. It is used to indicate whether dns or path style url requests are supported by the server. It accepts "dns", "path" or "auto" as valid values. By default, it is set to "auto" and SDK automatically determines the type of url lookup to use.

Example - Minio Cloud Storage

Minio server displays URL, access and secret keys.

mc config host add minio http://192.168.1.51 BKIKJAA5BMMU2RHO6IBB V7f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12

Example - Amazon S3 Cloud Storage

Get your AccessKeyID and SecretAccessKey by following AWS Credentials Guide.

mc config host add s3 https://s3.amazonaws.com BKIKJAA5BMMU2RHO6IBB V7f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12

Example - Google Cloud Storage

Get your AccessKeyID and SecretAccessKey by following Google Credentials Guide

mc config host add gcs  https://storage.googleapis.com BKIKJAA5BMMU2RHO6IBB V8f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12

NOTE: Google Cloud Storage only supports Legacy Signature Version 2, so you have to pick - S3v2

Test Your Setup

mc is pre-configured with https://play.minio.io:9000, aliased as "play". It is a hosted Minio server for testing and development purpose. To test Amazon S3, simply replace "play" with "s3" or the alias you used at the time of setup.

Example:

List all buckets from https://play.minio.io:9000

mc ls play
[2016-03-22 19:47:48 PDT]     0B my-bucketname/
[2016-03-22 22:01:07 PDT]     0B mytestbucket/
[2016-03-22 20:04:39 PDT]     0B mybucketname/
[2016-01-28 17:23:11 PST]     0B newbucket/
[2016-03-20 09:08:36 PDT]     0B s3git-test/

Make a bucket mb command creates a new bucket.

Example:

mc mb play/mybucket
Bucket created successfully `play/mybucket`.

Copy Objects cp command copies data from one or more sources to a target.

Example:

mc cp myobject.txt play/mybucket
myobject.txt:    14 B / 14 B  ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓  100.00 % 41 B/s 0

Everyday Use

Shell aliases

You may add shell aliases to override your common Unix tools.

alias ls='mc ls'
alias cp='mc cp'
alias cat='mc cat'
alias mkdir='mc mb'
alias pipe='mc pipe'
alias find='mc find'

Shell autocompletion

You may also download autocomplete/bash_autocomplete into /etc/bash_completion.d/ and rename it to mc. Don't forget to source the file to make it active on your current shell.

sudo wget https://raw.githubusercontent.com/minio/mc/master/autocomplete/bash_autocomplete -O /etc/bash_completion.d/mc
source /etc/bash_completion.d/mc

mc <TAB>
admin    config   diff     ls       mirror   policy   session  update   watch
cat      cp       events   mb       pipe     rm       share    version
