### Building a hotfix binary and container

To add a hotfix tag to the binary version and embed the relevant `commit-id` following build helpers are available

#### Builds the hotfix binary and uploads to https;//dl.min.io

```
λ CRED_DIR=/media/builder/minio make hotfix-push
```

# Download minio binary and signature file
RUN curl -s -q https://dl.min.io/server/minio/release/linux-${TARGETARCH}/archive/minio.${RELEASE} -o /go/bin/minio && \
    curl -s -q https://dl.min.io/server/minio/release/linux-${TARGETARCH}/archive/minio.${RELEASE}.minisig -o /go/bin/minio.minisig && \
    chmod +x /go/bin/minio

# Download mc binary and signature file

	@docker build -q --no-cache -t $(TAG) . -f Dockerfile

```sh

cd prometheus-*
```

Prometheus server is a single binary called `prometheus` (or `prometheus.exe` on Microsoft Windows). Run the binary and pass `--help` flag to see available options

```sh
./prometheus --help
usage: prometheus [<flags>]

# Install curl and minisign
RUN apk add -U --no-cache ca-certificates && \
    apk add -U --no-cache curl && \
    go install aead.dev/minisign/cmd/minisign@v0.2.1

# Download minio binary and signature file
RUN curl -s -q https://dl.min.io/server/minio/release/linux-${TARGETARCH}/archive/minio.${RELEASE}.fips -o /go/bin/minio && \

MinIO FIPS executables are available at <http://dl.min.io> - they are only published for `linux-amd64` architecture as binary files with the suffix `.fips`. We also publish corresponding container images to our official image repositories.

### 2. Run MinIO Server with Erasure Code

Example: Start MinIO server in a 12 drives setup, using MinIO binary.

```sh
minio server /data{1...12}
```

Example: Start MinIO server in a 8 drives setup, using MinIO Docker image.

```sh
podman run \
  -p 9000:9000 \
  -p 9001:9001 \
  --name minio \

ftp localhost -P 8021
Connected to localhost.

| xlMetaV2  | msgp object | All versions as single messagepack object
| [EOF] | |

### v1.1+

Version 1.1 added inline data, which will be placed after the metadata.

Therefore, the metadata is wrapped as a binary array for easy skipping.

| Entry          | Encoding       | Content
| ---------------|----------------|----------------------------------------
| xlHeader       | [4]byte        | `'X', 'L', '2', ' '`

# All other users may do anything other than call PutObject
allow {
 input.action != "s3:PutObject"
 input.owner == false
}
EOF
```

Then load the policy via OPA's REST API.

```
curl -X PUT --data-binary @example.rego \
  localhost:8181/v1/policies/putobject
```

### 4. Setup MinIO with OPA

Set the `MINIO_POLICY_PLUGIN_URL` as the endpoint that MinIO should send authorization requests to. Then start the server.
