MinIO Quickstart Guide

MinIO is a High Performance Object Storage released under Apache License v2.0. It is API compatible with Amazon S3 cloud storage service. Use MinIO to build high performance infrastructure for machine learning, analytics and application data workloads.

This README provides quickstart instructions on running MinIO on baremetal hardware, including Docker-based installations. For Kubernetes environments, use the MinIO Kubernetes Operator.

Docker Installation

Use the following commands to run a standalone MinIO server on a Docker container.

Standalone MinIO servers are best suited for early development and evaluation. Certain features such as versioning, object locking, and bucket replication require distributed deploying MinIO with Erasure Coding. For extended development and production, deploy MinIO with Erasure Coding enabled - specifically, with a minimum of 4 drives per MinIO server. See MinIO Erasure Code Quickstart Guide for more complete documentation.

Stable

Run the following command to run the latest stable image of MinIO on a Docker container using an ephemeral data volume:

docker run -p 9000:9000 minio/minio server /data

The MinIO deployment starts using default root credentials minioadmin:minioadmin. You can test the deployment using the MinIO Browser, an embedded web-based object browser built into MinIO Server. Point a web browser running on the host machine to http://127.0.0.1:9000 and log in with the root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.

You can also connect using any S3-compatible tool, such as the MinIO Client mc commandline tool. See Test using MinIO Client mc for more information on using the mc commandline tool. For application developers, see https://docs.min.io/docs/ and click MINIO SDKS in the navigation to view MinIO SDKs for supported languages.

NOTE: To deploy MinIO on Docker with persistent storage, you must map local persistent directories from the host OS to the container using the docker -v option. For example, -v /mnt/data:/data maps the host OS drive at /mnt/data to /data on the Docker container.

Edge

Run the following command to run the bleeding-edge image of MinIO on a Docker container using an ephemeral data volume:

docker run -p 9000:9000 minio/minio:edge server /data

NOTE: To deploy MinIO on Docker with persistent storage, you must map local persistent directories from the host OS to the container using the docker -v option. For example, -v /mnt/data:/data maps the host OS drive at /mnt/data to /data on the Docker container.

macOS

Use the following commands to run a standalone MinIO server on macOS.

Homebrew (recommended)

Run the following command to install the latest stable MinIO package using Homebrew. Replace /data with the path to the drive or directory in which you want MinIO to store data.

brew install minio/stable/minio
minio server /data

NOTE: If you previously installed minio using brew install minio then it is recommended that you reinstall minio from minio/stable/minio official repo instead.

brew uninstall minio
brew install minio/stable/minio

Binary Download

Use the following command to download and run a standalone MinIO server on macOS. Replace /data with the path to the drive or directory in which you want MinIO to store data.

wget https://dl.min.io/server/minio/release/darwin-amd64/minio
chmod +x minio
./minio server /data

GNU/Linux

Use the following command to run a standalone MinIO server on Linux hosts running 64-bit Intel/AMD architectures. Replace /data with the path to the drive or directory in which you want MinIO to store data.

wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio
./minio server /data

Replace /data with the path to the drive or directory in which you want MinIO to store data.

The following table lists supported architectures. Replace the wget URL with the architecture for your Linux host.

Microsoft Windows

To run MinIO on 64-bit Windows hosts, download the MinIO executable from the following URL:

https://dl.min.io/server/minio/release/windows-amd64/minio.exe

Use the following command to run a standalone MinIO server on the Windows host. Replace D:\ with the path to the drive or directory in which you want MinIO to store data. You must change the terminal or powershell directory to the location of the minio.exe executable, or add the path to that directory to the system $PATH:

minio.exe server D:\

Certain features such as versioning, object locking, and bucket replication require distributed deploying MinIO with Erasure Coding. For extended development and production, deploy MinIO with Erasure Coding enabled - specifically, with a minimum of 4 drives per MinIO server. See MinIO Erasure Code Quickstart Guide for more complete documentation.

FreeBSD

MinIO does not provide an official FreeBSD binary. However, FreeBSD maintains an upstream release using pkg:

pkg install minio
sysrc minio_enable=yes
sysrc minio_disks=/home/user/Photos
service minio start

Install from Source

Use the following commands to compile and run a standalone MinIO server 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 go1.15

GO111MODULE=on go get github.com/minio/minio

NOTE: Standalone MinIO servers are best suited for early development and evaluation. Certain features such as versioning, object locking, and bucket replication require distributed deploying MinIO with Erasure Coding. For extended development and production, deploy MinIO with Erasure Coding enabled - specifically, with a minimum of 4 drives per MinIO server. See MinIO Erasure Code Quickstart Guide for more complete documentation.

MinIO strongly recommends against using compiled-from-source MinIO servers for production environments.

Deployment Recommendations

Allow port access for Firewalls

By default MinIO uses the port 9000 to listen for incoming connections. If your platform blocks the port by default, you may need to enable access to the port.

ufw

For hosts with ufw enabled (Debian based distros), you can use ufw command to allow traffic to specific ports. Use below command to allow access to port 9000

ufw allow 9000

Below command enables all incoming traffic to ports ranging from 9000 to 9010.

ufw allow 9000:9010/tcp

firewall-cmd

For hosts with firewall-cmd enabled (CentOS), you can use firewall-cmd command to allow traffic to specific ports. Use below commands to allow access to port 9000

firewall-cmd --get-active-zones

This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is public, use

firewall-cmd --zone=public --add-port=9000/tcp --permanent

Note that permanent makes sure the rules are persistent across firewall start, restart or reload. Finally reload the firewall for changes to take effect.

firewall-cmd --reload

iptables

For hosts with iptables enabled (RHEL, CentOS, etc), you can use iptables command to enable all traffic coming to specific ports. Use below command to allow access to port 9000

iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart

Below command enables all incoming traffic to ports ranging from 9000 to 9010.

iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT
service iptables restart

Pre-existing data

When deployed on a single drive, MinIO server lets clients access any pre-existing data in the data directory. For example, if MinIO is started with the command minio server /mnt/data, any pre-existing data in the /mnt/data directory would be accessible to the clients.

The above statement is also valid for all gateway backends.

Test MinIO Connectivity

Test using MinIO Browser

MinIO Server comes with an embedded web based object browser. Point your web browser to http://127.0.0.1:9000 to ensure your server has started successfully.

Test using MinIO Client `mc`

mc provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services. Follow the MinIO Client Quickstart Guide for further instructions.

Upgrading MinIO

MinIO server supports rolling upgrades, i.e. you can update one MinIO instance at a time in a distributed cluster. This allows upgrades with no downtime. Upgrades can be done manually by replacing the binary with the latest release and restarting all servers in a rolling fashion. However, we recommend all our users to use mc admin update from the client. This will update all the nodes in the cluster simultaneously and restart them, as shown in the following command from the MinIO client (mc):

mc admin update <minio alias, e.g., myminio>

NOTE: some releases might not allow rolling upgrades, this is always called out in the release notes and it is generally advised to read release notes before upgrading. In such a situation mc admin update is the recommended upgrading mechanism to upgrade all servers at once.

Important things to remember during MinIO upgrades

mc admin update will only work if the user running MinIO has write access to the parent directory where the binary is located, for example if the current binary is at /usr/local/bin/minio, you would need write access to /usr/local/bin.
mc admin update updates and restarts all servers simultaneously, applications would retry and continue their respective operations upon upgrade.
mc admin update is disabled in kubernetes/container environments, container environments provide their own mechanisms to rollout of updates.
In the case of federated setups mc admin update should be run against each cluster individually. Avoid updating mc to any new releases until all clusters have been successfully updated.
If using kes as KMS with MinIO, just replace the binary and restart kes more information about kes can be found here
If using Vault as KMS with MinIO, ensure you have followed the Vault upgrade procedure outlined here: https://www.vaultproject.io/docs/upgrading/index.html
If using etcd with MinIO for the federation, ensure you have followed the etcd upgrade procedure outlined here: https://github.com/etcd-io/etcd/blob/master/Documentation/upgrades/upgrading-etcd.md
