Java tomcat docker compose无法访问共享卷

我正试图在tomcat docker容器上部署一场战争。 默认情况下，可以在listined http端口上访问Tomcat管理器。 我不想要这种行为。为了避免这种情况，我创建了一个ROOT.xml上下文文件，如下所述

ROOT.xml通过docker卷共享，并包含上下文定义：

<Context docBase="/usr/tomcat/custom-webapp/app.war" reloadable="true" />

我确信app.war文件已装入容器中。当我进入容器或运行tomcatls/usr/local/tomcat/customwebapp时，我可以看到它。但在启动时，tomcat似乎找不到该文件。这对我来说很奇怪

有人知道为什么tomcat容器无法访问app.war文件吗

下面是错误跟踪
