java.lang.AssertionError:Docker环境的可用内存超过2GB

我一直在为使用docker的程序创建测试。一切都很顺利，直到我在任何测试开始时突然遇到这个问题

ℹ︎ Checking the system...
    ✔ Docker version is newer than 1.6.0
    ✘ Docker environment has more than 2GB free

第24行是我称之为“new GenericContainer”的行

我想不出有什么问题。我的电脑有16GB内存，其中10GB应该是免费的。在问题出现之前，我今天成功地运行了大约10次测试，我尝试重新启动计算机，但没有任何帮助。

它是检查您的磁盘空间，而不是RAM。谢谢！通过从磁盘中删除一些文件，我解决了这个问题。在我的情况下，即使我从磁盘中删除了文件，唯一有效的命令是：docker stop$（docker ps-a-q）；docker kill$（docker ps-q）；docker rm$（docker ps-a-q）；docker rmi$（docker images-q）

public class MongoDBTest
{
  @ClassRule
  public static GenericContainer mongodb = new GenericContainer("mongo:3.6")
          .withExposedPorts(27017)
          .waitingFor(Wait.forListeningPort());
