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 alias command.

GitLab CI

When using the Docker container in GitLab CI, you must set the entrypoint to an empty string.

deploy:
  image:
    name: minio/mc
    entrypoint: ['']
  stage: deploy
  before_script:
    - mc alias set minio $MINIO_HOST $MINIO_ACCESS_KEY $MINIO_SECRET_KEY
  script:
    - mc cp <source> <destination>

Install from Source

Source installation is only intended for developers and advanced users. If you do not have a working Golang environment, please follow How to install Golang. Minimum version required is go1.17

go install github.com/minio/mc@latest

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 alias set <ALIAS> <YOUR-S3-ENDPOINT> <YOUR-ACCESS-KEY> <YOUR-SECRET-KEY> --api <API-SIGNATURE> --path <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".

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

Example - MinIO Cloud Storage

MinIO server startup banner displays URL, access and secret keys.

mc alias set minio http://192.168.1.51 BKIKJAA5BMMU2RHO6IBB V7f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12
Example - Amazon S3 Cloud Storage

Get your AccessKeyID and SecretAccessKey by following AWS Credentials Guide.

mc alias set s3 https://s3.amazonaws.com BKIKJAA5BMMU2RHO6IBB V7f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12

Note: As an IAM user on Amazon S3 you need to make sure the user has full access to the buckets or set the following restricted policy for your IAM user

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowBucketStat",
            "Effect": "Allow",
            "Action": [
                "s3:HeadBucket"
            ],
            "Resource": "*"
        },
        {
            "Sid": "AllowThisBucketOnly",
            "Effect": "Allow",
            "Action": "s3:*",
            "Resource": [
                "arn:aws:s3:::<your-restricted-bucket>/*",
                "arn:aws:s3:::<your-restricted-bucket>"
            ]
        }
    ]
}
Example - Google Cloud Storage

Get your AccessKeyID and SecretAccessKey by following Google Credentials Guide

mc alias set gcs  https://storage.googleapis.com BKIKJAA5BMMU2RHO6IBB V8f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12

Test Your Setup

mc is pre-configured with https://play.min.io, 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.min.io

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

In case you are using bash, zsh or fish. Shell completion is embedded by default in mc, to install auto-completion use mc --autocompletion. Restart the shell, mc will auto-complete commands as shown below.

mc <TAB>
admin    config   diff     find     ls       mirror   policy   session  sql      update   watch
cat      cp       event    head     mb       pipe     rm       share    stat     version
