为什么neo4j停靠容器重新启动会导致容器挂起并退出

Question

我创建了一个定制的坞映像，以便启动包装器脚本来加载初始数据。当我第一次启动这个容器时，有时会失败，但我想是缓存了一些东西，或者我没有足够的时间等待neo4j的启动。

当我停止容器并重新启动它时，问题就出现了。它下载插件，然后它似乎挂起，它不能使进程到前台。

./wrapper.sh: line 57: fg: job has terminated In /logs/debug.log当我重新启动容器时没有日志。所以很难理解到底发生了什么。有什么许可吗？

这里是我的包装文件

你知道如何解决这个问题吗?或者至少知道出了什么问题？

这似乎发生在最新的版本，当我切换到了新4j:4.2，然后它开始正常工作。

我试图运行干净的映像，但使用包装器脚本，在我看来，4.4.10在关闭时存在一些问题，可能留下了一些不一致的状态
