version: "3" services: tomcat: image: "tomcat:latest" restart: always container_name: tomcat environment: - TZ=Asia/Shanghai ports: - 8888:8080 volumes: - ./conf/server.xml:/usr/local/tomcat/conf/server.xml - ./logs:/usr/local/tomcat/logs - ./webapps:/usr/local/tomcat/webapps

这个Docker Compose文件看起来很不错，您已经正确地将Tomcat容器映射到主机端口8888和本地的server.xml、logs和webapps目录。但是，您的server.xml配置文件可能有问题，因此Tomcat容器可能无法正常启动。您可以检查server.xml文件是否正确配置了Tomcat实例。以下是一个示例server.xml文件的示例配置：

<?xml version="1.0" encoding="UTF-8"?>
<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <Listener className="org.apache.catalina.core.JasperListener" />
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

  <GlobalNamingResources>
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

  <Service name="Catalina">
    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

        <Context path="" docBase="ROOT" debug="0" reloadable="true"/>
      </Host>
    </Engine>
  </Service>
</Server>

如果您的server.xml文件类似于上面的示例，并且正确配置了Tomcat实例，那么您的Docker Compose文件应该能够正常工作了。
