# Introduction

This document outlines how to make hotfix binaries and containers for MinIO?. The main focus in this article is about how to backport patches to a specific branch and finally building binaries/containers.

## Pre-pre requisite

- A working knowledge of MinIO codebase and its various components.
- A working knowledge of AWS S3 API behaviors and corner cases.

## Pre-requisite for backporting any fixes

	flag.StringVar(&prefix, "prefix", "", "Add prefix to all objects")
	flag.StringVar(&object, "object", "", "Select an object")
	flag.StringVar(&deploymentID, "deployment-id", "", "MinIO deployment ID, obtained from 'format.json'")
	flag.IntVar(&setCount, "set-count", 0, "Total set count")
	flag.IntVar(&shards, "shards", 0, "Total shards count")
	flag.BoolVar(&verbose, "v", false, "Display all objects")

	flag.Parse()

and you'll receive a more detailed response to your email within 72 hours indicating the next steps
in handling your report.

Please, provide a detailed explanation of the issue. In particular, outline the type of the security
issue (DoS, authentication bypass, information disclose, ...) and the assumptions you're making (e.g. do
you need access credentials for a successful exploit).

## Batch Jobs Terminology

### Job
A job is the basic unit of work for MinIO Batch Job. A job is a self describing YAML, once this YAML is submitted and evaluated - MinIO performs the requested actions on each of the objects obtained under the described criteria in job YAML file.

### Type

	}

	sts, err := credentials.NewSTSClientGrants(stsEndpoint, getTokenExpiry)
	if err != nil {
		log.Fatal(err)
	}

	// Uncomment this to use MinIO API operations by initializing minio
	// client with obtained credentials.

	opts := &minio.Options{
		Creds:        sts,
		BucketLookup: minio.BucketLookupAuto,
	}

	u, err := url.Parse(stsEndpoint)
	if err != nil {
		log.Fatal(err)
	}

and then click "Grant access"

On the browser now you shall see the list of buckets output, along with your temporary credentials obtained from MinIO.

```
{
 "buckets": [
  "dl.minio.equipment",
  "dl.minio.service-fulfillment",
  "testbucket"
 ],
 "credentials": {
  "AccessKeyID": "Q31CVS1PSCJ4OTK2YVEM",

| Params        | Value                                              |
| :--           | :--                                                |
| *Type*        | *Integer*                                          |

## 2. Use an Existing Key and Certificate with MinIO
