### Set legal hold on an object

PutObject API allows setting legal hold using `x-amz-object-lock-legal-hold` header.

```sh

			return nil, err
		}

		// Pass should be an integer.
		if _, err := strconv.Atoi(fields[5]); err != nil {
			return nil, err
		}

		mounts = append(mounts, mountInfo{
			Device:  fields[0],
			Path:    fields[1],
			FSType:  fields[2],
			Options: strings.Split(fields[3], ","),
			Freq:    fields[4],
			Pass:    fields[5],
		})
	}
	return mounts, nil

	}
	testCases := []struct {
		bucketName string
		objectName string

		// Expected output of GetObjectInfo.
		result ObjectInfo
		err    error
		// Flag indicating whether the test is expected to pass or not.
		shouldPass bool
	}{
		// Test cases with invalid bucket names ( Test number 1-4 ).
		{".test", "", ObjectInfo{}, BucketNameInvalid{Bucket: ".test"}, false},

## MinIO Docker Tips

### MinIO Custom Access and Secret Keys

To override MinIO's auto-generated keys, you may pass secret and access keys explicitly as environment variables. MinIO server also allows regular strings as access and secret keys.

#### GNU/Linux and macOS (custom access and secret keys)

```sh
docker run \
  -p 9000:9000 \

		t.Log(oi, err)

		result, err := obj.ListObjects(context.Background(), testCase.bucketName, "", "", "", 1000)
		if err != nil {
			t.Errorf("Test %d: %s:  Expected to pass, but failed with: <ERROR> %s", i+1, instanceType, err.Error())
			continue
		}

		if len(result.Objects) != len(testCase.objectsAfterDelete) {
