- [IV](#iv): is a randomly generated initialization vector. It is public and part of the object metadata.
- `context_values`: are values like the bucket and object name and other information which should be cryptographically bound to the KEK.

To summarize for any encrypted object there exists (at least) three different keys:

Install the chart, specifying the buckets you want to create after install:

```bash
helm install --set buckets[0].name=bucket1,buckets[0].policy=none,buckets[0].purge=false minio/minio
```

Description of the configuration parameters used above -

- `buckets[].name` - name of the bucket to create, must be a string with length > 0
- `buckets[].policy` - can be one of none|download|upload|public

KEY:
site  label the server and its location

ARGS:
name     (string)    name for the site e.g. "cal-rack0"
region   (string)    name of the location of the server e.g. "us-west-1"
comment  (sentence)  optionally add a comment to this setting
```

or environment variables

```
KEY:
site  label the server and its location

ARGS:
MINIO_SITE_NAME     (string)    name for the site e.g. "cal-rack0"

When you PUT an object in a versioning-enabled bucket, the noncurrent version is not overwritten. The following figure shows that when a new version of `spark.csv` is PUT into a bucket that already contains an object with the same name, the original object (ID = `ede336f2`) remains in the bucket, MinIO generates a new version (ID = `fae684da`), and adds the newer version to the bucket.

Type in expressions to have them evaluated.

- At the _scala>_ prompt, submit the job by typing the following commands, Replace node names, file name, and file location with your values:

```
scala> val file = sc.textFile("s3a://testbucket/testdata")
file: org.apache.spark.rdd.RDD[String] = s3a://testbucket/testdata MapPartitionsRDD[1] at textFile at <console>:24

## Highlights

Assuming `mc` is already [configured](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart)

```
mc admin config get myminio/ logger_webhook
logger_webhook:name1 auth_token="" endpoint=""
```

```
mc admin config set myminio logger_webhook:name1 auth_token="" endpoint="http://endpoint:port/path"
mc admin service restart myminio
```
