### Usage

```
minio server --config config.yaml
```

Lets you start MinIO server with all inputs to start MinIO server provided via this configuration file, once the configuration file is provided all other pre-existing values on disk for configuration are overridden by the new values set in this configuration file.

| `io_write_bytes`              | `counter` | Total bytes written by the process to the underlying storage system, /proc/[pid]/io write_bytes                | `server` |
| `start_time_seconds`          | `gauge`   | Start time for MinIO process in seconds since Unix epoc                                                        | `server` |

``MinIO`` community welcomes your contribution. To make the process as seamless as possible, we recommend you read this contribution guide.

## Development Workflow

Start by forking the MinIO GitHub repository, make changes in a branch and then send a pull request. We encourage pull requests to discuss code changes. Here are the steps in details:

### Setup your MinIO GitHub Repository

This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a
well defined data structure. To understand `xl.meta` here are the few things to start with

`xl.meta` carries first 8 bytes an XL header which describes the current format and the format version,
allowing the unmarshaller's to automatically use the right data structures to parse the subsequent content in the stream.

free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

OPA is enabled through MinIO's Access Management Plugin feature.

## Get started

### 1. Start OPA in a container

```sh
podman run -it \
    --name opa \
    --publish 8181:8181 \
    docker.io/openpolicyagent/opa:0.40.0-rootless \
       run --server \
           --log-format=json-pretty \

|      16 |                 2 |          16 |                       4 |                             4 |                              4 |

If one or more drives are offline at the start of a PutObject or NewMultipartUpload operation the object will have additional data
protection bits added automatically to provide the regular safety for these objects up to 50% of the number of drives.

- A pool interrupted during the decommission process, such as for a cluster restart, resumes from where it left off.

## How to decommission a pool

```
λ mc admin decommission start alias/ http://minio{1...2}/data{1...4}
```

## Status decommissioning a pool

### Decommissioning without args lists all pools

```
λ mc admin decommission status alias/

```
git clone https://github.com/minio/thumbnailer/
npm install
```

Then open the Thumbnailer config file at `config/webhook.json` and add the configuration for your MinIO server and then start Thumbnailer by

```
NODE_ENV=webhook node thumbnail-webhook.js
```

```sh
go run access-manager-plugin.go
```

This program, lets the admin user perform any action and prevents all other users from performing `s3:Put*` operations.

In another terminal start MinIO:

```sh
export MINIO_CI_CD=1
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123
export MINIO_POLICY_PLUGIN_URL=http://localhost:8080/
minio server /tmp/disk{1...4}
```
