/// tip | 豆知識

IP `0.0.0.0` は、そのマシン/サーバーで利用可能なすべての IP で待ち受けることを意味する表現として一般的に使われます。

///

ドキュメント UI では、この API の `server` が（プロキシの背後で）`/api/v1` にあることを宣言する OpenAPI スキーマも必要です。例えば:

```JSON hl_lines="4-8"
{
    "openapi": "3.1.0",

            // When - calculate percentage free
            double percentFree = (allocInfo.getFree() * 100.0) / allocInfo.getCapacity();

            // Then
            assertEquals(25.0, percentFree, 0.001);
        }

        @Test
        @DisplayName("Should support available space check pattern")
        void shouldSupportAvailableSpaceCheckPattern() {
            // Given
