## Getting Started

* GORM Guides [https://gorm.io](https://gorm.io)

#### GNU/Linux and macOS (regular user)

On Linux and macOS you can use `--user` to run the container as regular user.

> NOTE: make sure --user has write permission to *${HOME}/data* prior to using `--user`.

```sh
mkdir -p ${HOME}/data
docker run \
  -p 9000:9000 \
  -p 9001:9001 \
  --user $(id -u):$(id -g) \
  --name minio1 \

`/<user-running-minio>/.minio/certs`.

*Tip*: In a standard Kubernetes configuration, this will be `/root/.minio/certs`. Kubernetes will mount the secrets volume read-only,

 * Remove global state
 * Allow per context configuration
 * Logging through SLF4J
 * Drop pre-java 1.7 support
 * Unify authentication subsystem, NTLMSSP/Kerberos support
 * Large ReadX/WriteX support
 * Streaming list operations
 * NtTransNotifyChange support
 * Google patches: various bugfixes, lastAccess support, retrying requests
 * A proper test suite
 * Various fixes

## Cluster probe

### Cluster-writeable probe

The reply is '200 OK' if cluster has write quorum if not it returns '503 Service Unavailable'.

```

![quota](https://raw.githubusercontent.com/minio/minio/master/docs/bucket/quota/bucketquota.png)

Buckets can be configured to have `Hard` quota - it disallows writes to the bucket after configured quota limit is reached.

## Prerequisites

- Install MinIO - [MinIO Quickstart Guide](https://min.io/docs/minio/linux/index.html#procedure).

delete_cleanup_interval         (duration)  set to change intervals when deleted objects are permanently deleted from ".trash" folder (default: '5m')
odirect                         (boolean)   set to enable or disable O_DIRECT for read and writes under special conditions. NOTE: do not disable O_DIRECT without prior testing (default: 'on')
root_access                     (boolean)   turn 'off' root credential access for all API calls including s3, admin operations (default: 'on')

- If you plan to use `mc admin update`, MinIO process must have write access to the parent directory where the binary is present on the host system.
- `mc admin update` is not supported and should be avoided in kubernetes/container environments, please upgrade containers by upgrading relevant container images.
