MinIO

MinIO offers high-performance, S3 compatible object storage.

You can install multiple MinIO instances on the same node from the :ref:`software_center-section`.

Configuration

MinIO needs two dedicated virtual host, a FQDN like minio-api.nethserver.org and minio-ui.nethserver.org.

Before proceeding with the configuration, make sure to create the corresponding name records inside your DNS server. If you are planning to use a Let's Encrypt certificate as default, make also sure to have corresponding public DNS records.

How to configure:

  1. access the application configuration page and enter the API server host name: this will be the FQDN used by hosts to connect to S3 services
  2. fill the Web interface host name: you will be able to configure your MinIO instance from this FQDN
  3. enable Let's Encrypt option accordingly to your needs
  4. click the :guilabel:`Save` button
  5. open the entered host name inside the browser, eg: https://minio-ui.nethserver.org.

Configure local disks

Setting up MinIO with a locally attached USB/SCSI disk provides two key benefits:

  1. data privacy: if you're cautious about sharing data with cloud providers, this setup allows you to retain control over your information and prevent third-party access
  2. local data ownership: by utilizing a local disk, you maintain complete data control within your own environment. This improves security and minimizes dependence on external services

Instructions

As system root user, follow these steps for a disk named scsi-disk1:

  1. Create a mount point: make a directory to serve as the mount point for the disk:

    mkdir -p /mnt/data

  2. Automate mount at boot: ensure the disk is automatically mounted during boot by modifying /etc/fstab:

    echo '/dev/disk/by-id/scsi-disk1 /mnt/data ext4 defaults,nofail,discard 0 0' >> /etc/fstab
systemctl daemon-reload

  3. Mount the disk: physically attach the disk using the mount command:

    mount /mnt/data

  4. Ensure MinIO access: allow the MinIO instance (e.g., minio1) to access the disk:

    chown minio1:minio1 /mnt/data/

Finally, within the module's user interface, configure the Storage path to be /mnt/data. Please note that the above path won't be part of the backup.
