We will deploy the S3‑compatible object storage [RustFS](https://rustfs.com/) to [Fly.io](https://fly.io/). The deployment will fit within the free tier limits.

Assume you are already logged in to Fly.io using the `flyctl` command.

Create the following `fly.toml`:

```toml
primary_region = 'nrt'

[experimental]
  cmd = ['--console-enable', '/data']

[build]
  image = 'rustfs/rustfs:latest'

[env]
  RUSTFS_ADDRESS = '0.0.0.0:9000'
  RUSTFS_CONSOLE_ADDRESS = '0.0.0.0:9001'
  RUSTFS_CONSOLE_ENABLE = 'true'

[[mounts]]
  source = 'rustfs_data'
  destination = '/data'

[[services]]
  protocol = 'tcp'
  internal_port = 9000

  [[services.ports]]
    port = 80
    handlers = ['http']

  [[services.ports]]
    port = 443
    handlers = ['tls', 'http']

[[services]]
  protocol = 'tcp'
  internal_port = 9001

  [[services.ports]]
    port = 9001
    handlers = ['http']

  [[services.ports]]
    port = 8443
    handlers = ['tls', 'http']

[[vm]]
  cpu_kind = 'shared'
  cpus = 1
  memory_mb = 256
```

Deploy with the following commands:

```bash
flyctl apps create --name rustfs --machines
flyctl secrets set -a rustfs  RUSTFS_ACCESS_KEY=xxxxxxxxx
flyctl secrets set -a rustfs RUSTFS_SECRET_KEY=xxxxxxxxx
flyctl volumes create rustfs_data -a rustfs --size 3 --region nrt
flyctl deploy -a rustfs
flyctl logs -a rustfs
```

You can check the URL via the `Hostname` shown by `flyctl status -a rustfs`.

- `https://<Hostname>` … S3 API URL  
- `https://<Hostname>:8443` … Console URL

Access the Console. To log in, click the gear icon in the top‑right corner and set the **Server Address** to the S3 API URL.

You can now log in using the `ACCESS_KEY` and `SECRET_KEY` you set as secrets.

The `aws` CLI can be used as follows:

```bash
aws configure --profile rustfs
# Set ACCESS_KEY and SECRET_KEY. Region can be anything.
aws --profile rustfs --endpoint-url https://<Hostname> s3 ls
```
