# MinIO object storage

Note: As of February 13, 2026, MinIO is archived and no longer maintained, so you are probably better off using a different option. This guide is left online as reference for now.

MinIO was a high-performance object storage that was API compatible to Amazons Simple Storage Service (S3), but was open source and written in Go. It could be used as a building block for applications involving file storage and file transmission and while its native to the cloud, it turns out one can also use it on gokrazy. :)

## Step 1: Install MinIO to your gokrazy device

Add the `minio` program to your gokrazy instance:

    gok add github.com/minio/minio
    # Automatically initialize a file system on the /perm partition on first boot:
    gok add github.com/gokrazy/mkfs

## Step 2: Configuring the environment variables and command-line flags

Then, open your instance’s `config.json` in your editor:

    gok edit

And configure Package config: Command-line flags and Package config: Environment variables:

    {
        "Hostname": "storage",
        "Packages": [
            "github.com/gokrazy/fbstatus",
            "github.com/gokrazy/hello",
            "github.com/gokrazy/serial-busybox",
            "github.com/gokrazy/breakglass",
            "github.com/minio/minio",
            "github.com/gokrazy/mkfs"
        ],
        "PackageConfig": {
            "github.com/minio/minio": {
                "CommandLineFlags": [
                    "server",
                    "--address",
                    ":3001",
                    "--console-address",
                    ":3002",
                    "/perm/minio/"
                ],
                "Environment": [
                    "MINIO_ROOT_USER=minio",
                    "MINIO_ROOT_PASSWORD=minio-on-gokrazy"
                ]
            }
        }
    }

Then, deploy as usual:

    gok update

A few things can be noted here:

- There are nice practical examples on the different options once you execute `minio server --help` if you have it installed locally or more advanced use cases in the official MinIO docs.

- The ports for the storage server and console do not have to be explicitly set, but for me the default port collided with another service (Port 9000). If no port is set the console just chooses an arbitrary free one.

- For some reason the `HOME` variable has to be set to the storage folder. See Issue #12641 on why that is the case. As default gokrazy sets `HOME` to `HOME=/perm/<cmd>`, so if you want to change your storage location to something different modify the `Environment` field accordingly.

## Step 3: Test whether the setup was successful

If you have the `mc` command installed you can check out whether your installation of MinIO really works:

    $ mc alias set gokrazy http://gokrazy:3001 minio minio-on-gokrazy
    Added `gokrazy` successfully.
    $ mc ls gokrazy
    $ mc mb gokrazy/testbucket
    Bucket created successfully `gokrazy/testbucket`.
    $ mc ls gokrazy
    [2021-09-15 16:40:16 CEST]     0B testbucket/

Also check out the output in the logs on the gokrazy webinterface and login into the MinIO management console (http://gokrazy:3002 in this guide) to create service accounts view logs, bucket contents and more.
