minio-sampler (aka minsampler) borrows heavily from potman, minio-incinerator, clusterfurnace and cephsmelter to build a virtualbox minio cluster .
It is a sampler environment matching the HOWTO at How To Set Up a Minio Cluster From Potluck, Complete With Nextcloud, Monitoring And Alerting.
Do not run in production!
This is a testing environment to show minio running on FreeBSD, with consul, nomad, and the Beast-of-Argh one-pot monitoring solution providing prometheus, grafana, loki, alertmanager, plus a nextcloud nomad image, configured to use minio S3 as file storage, and a mariadb pot image for the nextcloud database.
As of 2022-11-24 everything works EXCEPT automatic nextcloud install. You can evaluate minio and the monitoring systems in the meantime.
This will bring up 2 minio servers:
- minio1 (8GB, 4 attached disks)
- minio2 (4GB, 4 attached disks)
The host computer running minio-sampler needs at least 16 CPU threads, 16GB memory, plus 50GB disk space, preferably high speed SSD. The setup takes an hour or so with packbox step included.
To create your own sampler, init the VMs:
git clone https://github.com/hnygd/minio-sampler
cd minio-sampler
(edit) config.ini and set ACCESSIP to a free IP on LAN, and set DISKSIZE
export PATH=$(pwd)/bin:$PATH
(optional: sudo chmod 777 /tmp)
minsampler init mysample
cd mysample
minsampler packbox
minsampler startvms
vagrant ssh minio1
OR
open http://ACCESSIP
...
./preparenextcloud.sh # not working
...
minsampler status
...
minsampler stopvms
minsampler destroyvms
minio-sampler requires
- ansible
- bash
- git
- packer
- vagrant
- virtualbox
Please see Detailed Install FreeBSD & Linux
Usage: minsampler command [options]
Commands:
destroyvms -- Destroy VMs
help -- Show usage
init -- Initialize new minio-sampler
packbox -- Create vm box image
startvms -- Start (and provision) VMs
status -- Show status
stopvms -- Stop VMs
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.
Everything is accessible via frontend at http://ACCESSIP
Virtual disks are saved in the minio-sampler 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 2GB disk, use 2000. This is the default.
Do not add the metric M, or MB or GB! It won't work.
Eight (8) 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 running minsampler init <name>.
The default dashboard with links to all the included tools is http://ACCESSIP. There is a default index pahe with links to the tools.
Where https is applicable, please accept the self-signed certificate. You might need to do this twice, even refresh the page, to get the minio dashboard.
The Minio web interface is available via nginx reverse proxy at https://ACCESSIP:19000 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 sampler and samplerpasswordislong to access the dashboard.
You can now create a bucket and explore settings.
The Grafana web interface is available via nginx reverse proxy at http://ACCESSIP:13000.
Login with username admin and password sampler.
The Prometheus web interface is available via nginx reverse proxy at http://ACCESSIP:19090 and no credentials.
The Alertmanager web interface is available via nginx reverse proxy at http://ACCESSIP:19093 and no credentials.
The Consul web interface is available nginx reverse proxy at http://ACCESSIP:18500 and no credentials.
The Nomad web interface is available nginx reverse proxy at http://ACCESSIP:14646 and no credentials.
The Traefik web interface is available nginx reverse proxy at http://ACCESSIP:19002 and no credentials.
There is a Nextcloud instance available at https://ACCESSIP:10443.
The admin username is sampler and password sampler123.
The automatic setup script is currently not working in this specialised setup.
