Deploying MinIO Server for S3 connectivity

MinIO is a software-defined high performance distributed object storage server.

If your a customer requiring direct on-prem storage does not support S3-compatible interface, Minio is recommended as a service for S3 interface. MinIO is a software-defined high performance distributed object storage server. You can run MinIO on consumer or enterprise-grade hardware and a variety of operating systems and architectures.

Considerations Checklist

Please use the following "Linux" checklist when planning the software configuration for a production, distributed MinIO deployment.

https://min.io/docs/minio/linux/operations/checklists/software.html

Prerequisites

Set up a data store by mounting storage to a designated path like /mnt/store1. For instance, use a local folder such as /data to store your data. Make sure to grant Read/Write permissions to the mount path and open the firewall to port 9000 for S3 APIs. Additionally, consider opening port 9001 for the Web Console if needed. Don't forget to secure your data with a TLS certificate.

Install MinIO

Myota exclusively functions on Linux due to Windows having object names that are incompatible. While S3 and Minio on Linux allow the use of question marks ('?') in object names, Minio on Windows does not support this feature.

We recommend Ubuntu as host machine of Minio server

sudo dpkg -i minio.deb

Add minio user and group
groupadd -r minio-user

useradd -M -r -g minio-user minio-user

Prepare directory to store Minio data based on your setup (e.g. local storage, NFS mount, etc.)
mkdir /data

chown minio-user:minio-user /data

Create minio.service. Open the service file (e.g. Ubuntu, /usr/lib/systemd/system/minio.service). Check User, Group are matched with your minio user (e.g. minio-user) and path at EnvironmentFile (/etc/default/minio)

vi /usr/lib/systemd/system/minio.service

Update environment file (/etc/default/minio)
Change MINIO_ROOT_USER, MINIO_ROOT_PASSWORD, and MINIO_VOLUMES
With default setup, Web Console port is 9001 and API port is 9000. Note that Comment out MINIO_SERVER_URL to receive request from all interfaces.

vi /etc/default/minio

# MINIO_ROOT_USER and MINIO_ROOT_PASSWORD sets the root account for the MinIO server.

# This user has unrestricted permissions to perform S3 and administrative API operations on any resource in the deployment.

# Omit to use the default values 'minioadmin:minioadmin'.

# MinIO recommends setting non-default values as a best practice, regardless of environment

MINIO_ROOT_USER=your_admin_user

MINIO_ROOT_PASSWORD=your_admin_password

# MINIO_VOLUMES sets the storage volume or path to use for the MinIO server.

MINIO_VOLUMES="/data"

# MINIO_OPTS sets any additional commandline options to pass to the MinIO server.

# For example, `--console-address :9001` sets the MinIO Console listen port

MINIO_OPTS="--console-address :9001"

# MINIO_SERVER_URL sets the hostname of the local machine for use with the MinIO Server

# MinIO assumes your network control plane can correctly resolve this hostname to the local machine

# Uncomment the following line and replace the value with the correct hostname for the local machine and port for the MinIO server (9000 by default).

# MINIO_SERVER_URL="https://YOUR_DOMAIN:9000"

Here in the status, look at addresses at S3-API and Console. It should have IP addresses of all network interfaces. In this example, there are private IP address, public IP address, and localhost.
Note that protocol is ‘http’ or ‘https’.

Visit Minio Web console at port 9001 and test S3 APIs at port 9000.

TLS configuration

There are two options to setup TSL.

Option 1: Setup certificate directly at Minio server

Put your certificate and private key like this structure.
/home/minio-user/.minio/
└── certs
├── YOUR_DOMAIN
│ ├── private.key
│ └── public.crt
├── private.key

└── public.crt
