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 buckets and objects
mb make a bucket
rb remove a bucket
cat display object contents
head display first 'n' lines of an object
pipe stream STDIN to an object
share generate URL for temporary access to an object
cp copy objects
mirror synchronize objects to a remote site
find search for objects
sql run sql queries on objects
stat stat contents of objects
diff list differences in object name, size, and date between buckets
rm remove objects
event manage object notifications
watch watch for object events
policy manage anonymous access to objects
admin manage MinIO servers
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.
macOS
Homebrew
Install mc packages using Homebrew
brew install minio/stable/mc

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 go1.12
GO111MODULE=on go get github.com/minio/mcAdd 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
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 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.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
