有时候，embedded-redis(lettuce)在测试中不断尝试重新连接

Question

我已经用嵌入式redis编写了redis测试用例，它在本地运行良好，没有任何问题。但是当我使用 jenkins 或 gitlab 迁移到 CI / CD 管道时。有时，我面临连接被拒绝的问题。

环境：

• spring-data-redis：2.2.8
• 生菜：5.5.2
• eu.monniot.redis：嵌入式redis：1.2.2

代码：

companion object {
        private lateinit var cluster: Redis

        @JvmStatic
        @BeforeAll
        @Timeout(120)
        fun beforeAll() {
            cluster = RedisCluster.Builder()
                .serverPorts(arrayListOf(16379, 17379, 18369, 19379))
                .numOfReplicates(1)
                .numOfRetries(12)
                .build()
            cluster.start()
        }

        @JvmStatic
        @AfterAll
        fun afterAll() {
            cluster.stop()
        }
    }

我无法修复它。有人可以帮助我吗？

我通过 github 操作遇到了与 CI/CD 管道相同的问题（并且在本地工作正常）。

问题解决了吗？
