我有这个 Dockerfile：
FROM tomcat:9.0-alpine
LABEL key="MyName"
ADD api.war /usr/local/tomcat/webapps/
EXPOSE 8080
CMD ["catalina.sh", "run"]
api.war 是简单的 Spring Boot 后端。适用于 java 19。使用

在 /webapps/ 的容器中我有 api.war 但是当点击 http://localhost:80/api 时，我得到了 404。
当我将该 api.war 文件部署到本地 tomcat 9 服务器时，它可以工作。 有什么问题？？感谢您的帮助
我尝试指定tomcat镜像版本。更改java版本。更改war文件名。还有更多其他教程
我将tomcat docker镜像的版本更改为9.0.79。并且应用程序可以运行。
