## 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

mc ready myminio

mc admin user add myminio/ minio123 minio123

mc admin policy create myminio/ deny-non-sse-kms-pol ./docs/iam/policies/deny-non-sse-kms-objects.json
mc admin policy create myminio/ deny-invalid-sse-kms-pol ./docs/iam/policies/deny-objects-with-invalid-sse-kms-key-id.json

mc admin policy attach myminio deny-non-sse-kms-pol --user minio123

minio server /mnt/data
```

### 5. Test with a regular IAM user

Ensure that `mc` is installed and the configured with the above server with the alias `myminio`.

```sh
# 1. Create a bucket and a user, and upload a file. These operations will succeed.
mc mb myminio/test
mc admin user add myminio foo foobar123
mc cp /etc/issue myminio/test/

# 2. Now access the server as user `foo`. These operations will also succeed.

minio server /tmp/disk{1...4}
```

Now, let's test it out with `mc`:

```sh
mc alias set myminio http://localhost:9000 minio minio123
mc ls myminio
mc mb myminio/test
mc cp /etc/issue myminio/test
mc admin user add myminio foo foobar123
export MC_HOST_foo=http://foo:foobar123@localhost:9000
mc ls foo
mc cp /etc/issue myminio/test/issue2
```

With the `mc` tool, the configuration is very simple to add. Let us say that the MinIO server is aliased as `myminio` in our mc configuration. Execute the following:

```
mc mb myminio/images
mc event add  myminio/images arn:minio:sqs::1:elasticsearch --suffix .jpg
mc event list myminio/images

SRC_DIR="/tmp/data"
DEST_DIR="/tmp/dest"

./mc admin config set "$ALIAS_NAME" api requests_max=400

OBJ_COUNT_AFTER_STOP=$(./mc ls "${ALIAS_NAME}"/"${BUCKET}"/initial-data/ | wc -l)
# Count should match the initial count of 10
if [ "${OBJ_COUNT_AFTER_STOP}" -ne 10 ]; then
	echo "Expected 10 objects; received ${OBJ_COUNT_AFTER_STOP}"
	exit 1
fi

./mc ready "${ALIAS_NAME}" --json

```
mc admin policy attach myminio putonly --group=newgroup
```

### 7. List all users or groups

List all enabled and disabled users.

```
mc admin user list myminio
```

List all enabled or disabled groups.

```
mc admin group list myminio
```

### 8. Configure `mc`

```

Assuming `mc` is already [configured](https://docs.min.io/community/minio-object-store/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"
