Multi-Node Multi-Drive MinIO S3 storage cluster in Docker Ansible role

This Ansible role deploys a 4 node MinIO S3 storage cluster in Docker containers.

Deployment

Prepare servers

1. See https://min.io/docs/minio/linux/operations/install-deploy-manage/deploy-minio-multi-node-multi-drive.html#minio-mnmd to get an idea about Multi-Node Multi-Drive MinIO deployment.
2. Make sure you have 4 servers with 4 additional disks for MinIO storage.
3. Format the 4 storage disks in XFS filesystem and label them as DISK1, DISK2, DISK3, DISK4 according to the above MinIO document.

TLS certificates

If you are going to use TLS, place fullchain certificate and private key files named after the DNS domain name into the files/certs/ directory.

Example:

- example.org.crt
- example.org.key

Ansbile inventory

Edit ansible/inventory.ini and specify your Nexus server addresses, username and ssh key or password, for example:

[minio]
minio-01   ansible_host=192.168.100.11   ansible_user=ubuntu   ansible_ssh_private_key_file=./ssh_key
minio-02   ansible_host=192.168.100.12   ansible_user=ubuntu   ansible_ssh_private_key_file=./ssh_key
minio-03   ansible_host=192.168.100.13   ansible_user=ubuntu   ansible_ssh_private_key_file=./ssh_key
minio-04   ansible_host=192.168.100.14   ansible_user=ubuntu   ansible_ssh_private_key_file=./ssh_key

Ansible vars

Edit ansible/roles/minio-cluster/defaults/main.yml and specify your network addresses, DNS domain name and other parameters, for example:

# ==== Network settings
# Docker network address on the docker0 bridge of the target hosts, ex: 172.17.0.0/16
docker_network: "172.17.0.0/16"
# LAN network address of the target hosts, ex: 10.1.1.0/24
lan_network: "10.0.0.0/24"
# DNS domain name
domain: "example.org"

# ==== MinIO
minio_version: "RELEASE.2023-06-29T05-12-28Z"
minio_root_user: "minioadmin"
minio_root_password: "minioadmin"
# Change schema to 'http' if you are not using TLS certificate
minio_cluster_url: "https://minio.{{ domain }}"

Install Docker on MinIO servers
