【问题描述】：
我一直在为使用 docker 的程序创建测试。一切都运行良好，直到我在任何测试开始时突然遇到这个问题

MongoDBTest 类以：
public class MongoDBTest
{
@ClassRule
public static GenericContainer mongodb = new GenericContainer("mongo:3.6")
.withExposedPorts(27017)
.waitingFor(Wait.forListeningPort());
第 24 行是我称之为“new GenericContainer”的地方
我无法弄清楚可能是什么问题。我的电脑有 16GB 的 RAM，其中大约 10GB 应该是空闲的。在问题出现之前，我今天成功运行了大约 10 次测试，我尝试重新启动计算机，但没有帮助。
【问题讨论】：
-
它正在检查您的 磁盘 空间，而不是您的 RAM。
-
谢谢！我通过从磁盘中删除一些文件解决了这个问题。
-
在我的情况下，即使我从磁盘中删除了文件，也只有这个命令有效：docker stop $(docker ps -a -q);docker kill $(docker ps -q) ;docker rm $(docker ps -a -q);docker rmi $(docker images -q)
