Spring Boot Tomcat已启动，但应用程序war文件未与docker composer文件一起部署

我在adoptopenjdk中使用了一个tomcat-9的镜像。docker-compose文件配置如下：

tomcat-server:
    image: tomcat:9.0.45-jdk11-adoptopenjdk-hotspot
    ports: 
      - "8081:8080"
    volumes:
      - /webapp/target/app.war:/usr/local/tomcat/webapps/app.war
    environment:
      - EUREKA.CLIENT.SERVICEURL.DEFAULTZONE=http://naming-server:8761/eureka
      - SPRING.REDIS.HOST=redis-cache-server

当我使用docker-compse文件启动tomcat时，日志显示它不会从提到的8081端口启动。它仍然在8080上启动。详细信息请参见日志。

我尝试了一些东西，但没有成功。我是不是漏了什么？

我能解决这个问题。解决方案是创建一个单独的docker文件来创建一个tomcat镜像，并在docker composer文件中使用它。
问题是，即使是战争复制到tomcat的webapps文件夹，它也不会部署。请参阅日志以供参考：

tomcat-server_1       | org.apache.catalina.startup.HostConfig.deployDirectory Deploying web application directory [/usr/local/tomcat/webapps/app.war]
tomcat-server_1       | org.apache.catalina.startup.HostConfig.deployDirectory Deployment of web application directory [/usr/local/tomcat/webapps/app.war] has finished in [361] ms
tomcat-server_1       | org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler ["http-nio-8080"]

由于镜像tomcat：9.0.45-jdk 11-adoptopenjdk-hotspot包含命令**'catalina.sh'，'run']**，docker-compose命令一执行，tomcat就启动了，在启动过程结束时，它将war文件复制到tomcat位置。所以它不会部署war文件。
这就是我发现的原因。（如果我错了，或者我错过了什么，请告诉我）。
所以最终的解决方案是这样的（这对我来说很有效）：
创建docker文件。（例如- Dockerfile_web）

#Take the Tomcat-9 image which supports AdoptOpenJDK
FROM tomcat:9.0.45-jdk11-adoptopenjdk-hotspot

#Copy the WAR file to tomcat
ADD ./webapp/target/attest.war /usr/local/tomcat/webapps/attest.war

#Allow execution (Not required, just added)
CMD chmod +x /usr/local/tomcat/bin/catalina.sh

接下来是在docker-compose文件中添加此文件引用。

web-app:
    build:
      context: .
      dockerfile: Dockerfile_Web
    ports: 
      - "8081:8080"
    networks:
      - app-network
    command: ['catalina.sh', 'run']
    environment:
      - EUREKA.CLIENT.SERVICEURL.DEFAULTZONE=http://naming-server:8761/eureka
      - SPRING.REDIS.HOST=redis-cache-server

一旦我用docker-compose up运行它，它就开始工作了。
