Introduction

minio-incinerator (aka mininc) borrows heavily from potman, clusterfurnace and cephsmelter to build a virtualbox minio cluster .

Do not run in production! This is a testing environment to show minio running on FreeBSD, with Consul, and the Beast-of-Argh monitoring solution alongside.

Outline

This will bring up 4 minio servers, configured for erasure coding, with a web interface:

• minio1 (8CPU, 4GB, 4 attached disks, nginx reverse proxy host, consul jail, beast-of-argh jail)
• minio2 (4CPU, 4GB, 4 attached disks)
• minio3 (4CPU, 4GB, 4 attached disks)
• minio4 (4CPU, 4GB, 4 attached disks)

Requirements

The host computer running minio-incinerator needs at least 16 CPU threads, 24GB memory, plus 200GB disk space, preferably high speed SSD.

Overview

Quickstart

To create your own incinerator, init the VMs:

git clone https://github.com/bretton/minio-incinerator.git
cd minio-incinerator

  (edit) config.ini and set ACCESSIP to a free IP on LAN, and set DISKSIZE

export PATH=$(pwd)/bin:$PATH
(optional: sudo chmod 775 /tmp)
mininc init mycluster
cd mycluster
mininc packbox
mininc startvms
...
mininc status
...

Stopping

mininc stopvms

Destroying

mininc destroyvms

Dependencies

minio-incinerator requires

• ansible
• bash
• git
• packer
• vagrant
• virtualbox

Installation and Operation

FreeBSD

(todo: add steps from https://docs.freebsd.org/en/books/handbook/virtualization/#virtualization-host-virtualbox )

Hosts which underwent an upgrade from 13.0 to 13.1

Please see the ERRATA file for info on fixing a broken upgrade.

Install for FreeBSD

Install packages, start services and configure permissions and networks

pkg install bash git packer py39-ansible py39-packaging vagrant virtualbox-ose
service vboxnet enable
service vboxnet start
    
(sudo) pw groupmod vboxusers -m <username>

mkdir -p /usr/local/etc/vbox
vi /usr/local/etc/vbox/networks.conf

(add, with asterisk; this is extremely broad)

* 0.0.0.0/0

Add to /etc/rc.conf because the host needs to be a router for private networks in Virtualbox to get internet access

gateway_enable="YES"

Restart networking (may pause ssh session for a bit)

sudo service netif restart && sudo service routing restart

edit .profile, add the following, adjusting for username

PATH=/home/<username>/minio-incinerator/bin:$PATH; export PATH

Download and configure minio-incinerator:

git clone https://github.com/bretton/minio-incinerator
cd minio-incinerator

  (edit) config.ini and set ACCESSIP to a free IP on LAN, and set DISKSIZE

export PATH=$(pwd)/bin:$PATH
(optional: sudo chmod 775 /tmp)
mininc init -v mycluster
cd mycluster
mininc packbox
mininc startvms

  vagrant ssh minio1   
  vagrant ssh minio2
  vagrant ssh minio3
  vagrant ssh minio4

Ubuntu 20.04 with Virtualbox

Install necessary packages

sudo apt-get install curl wget -y
sudo apt-get install ruby-full -y   # Ubuntu 20.04 is Ruby 2.7

sudo add-apt-repository ppa:git-core/ppa -y
sudo apt-get update
sudo apt-get install git -y

sudo apt-get install ansible virtualbox -y

curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -
sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"
sudo apt-get update && sudo apt-get install packer vagrant

Download and configure minio-incinerator:

git clone https://github.com/bretton/minio-incinerator.git
cd minio-incinerator

  (edit) config.ini and set ACCESSIP to a free IP on LAN, and set DISKSIZE

export PATH=$(pwd)/bin:$PATH
mininc init -v mycluster
cd mycluster
mininc packbox
mininc startvms

  vagrant ssh minio1   
  vagrant ssh minio2
  vagrant ssh minio3
  vagrant ssh minio4

Usage

Usage: mininc command [options]

Commands:
    destroyvms  -- Destroy VMs
    help        -- Show usage
    init        -- Initialize new minio-incinerator
    packbox     -- Create vm box image
    startvms    -- Start (and provision) VMs
    status      -- Show status
    stopvms     -- Stop VMs

Minio Dashboard

The Minio web interface is available via nginx reverse proxy at https://ACCESSIP for the IP address set in ACCESSIP variable of config.ini.

Accept the self-signed certificate TWICE. First is for nginx, second minio. Remember, this is not a production-ready environment.

Login with user demoadmin and NP4c2KzyESKCIEsDk2I2Dmb2HAFsGSxec30Uxiqz to access the dashboard.

You can now create a bucket and explore settings.

config.ini

Access IP

A virtual interface is created with a free IP address from the LAN. You must provide this free IP address in config.ini in the ACCESSIP section.

Disk Sizes

Virtual disks are saved in the minio-incinerator directory for the duration of running the program.

Set the size of the virtual disks in config.ini in the DISKSIZE section.

Input disk size in thousands of MB, where 10000 (MB) is the same as 10GB.

To set a 20GB disk, use 20000.

Do not add the metric M, or MB or GB! It won't work.

Sixteen (16) virtual drives will be created of this size, so ensure you have sufficient disk space!

A basic check is done to see if the input figures can be catered to, on init.
