在將WAR部署到tomcat docker容器后總是得到404

Question

我有一個grails應用程序，該應用程序已經運行，並且已通過Tomcat8 Jre8上的Elastic Beanstalk部署到了AWS。

我現在正嘗試將其部署在多碼頭環境中，並且我的行為很奇怪。

我正在使用tomcat:8.0-jre8 （ https://hub.docker.com/r/library/tomcat/ ）作為容器的映像，並且通過將war文件放在<tomcat_home>/webapps ，該映像上的部署非常簡單<tomcat_home>/webapps 。 另外，我正在將端口8080映射到外界。 因此，docker-compose的相關部分如下所示：

api:
  image: tomcat:8.0-jre8
  container_name: api
  volumes:
    - ./deployment/api:/usr/local/tomcat/webapps
  external_links:
    - mysql:mysql
  ports:
    - "8080:8080"

根據日志，該應用程序已成功部署，甚至正在應用liquibase遷移：

但是，當我嘗試訪問現有端點中的任何一個時，都將返回404。

現在，同樣基於日志，請求實際上正在到達服務器：

==> ./logs/localhost_access_log.2016-11-21.txt <==

172.17.0.1 - - [21/Nov/2016:07:28:46 +0000] "POST /api/user/register HTTP/1.1" 404 -

我什至該如何調試該問題？ 我想念什么？ 日志中沒有什么特別的。

此外，我嘗試了不同版本的tomcat，包括在AWS EBS上運行的確切版本。 另外，嘗試通過nginx處理請求，結果相同。

您的war文件名是priz-0.5.war 。 因此上下文名稱也為priz-0.5 。 您必須致電例如http://localhost:8080/priz-0.5

如果您想像http://localhost:8080/一樣調用它，只需將war-File重命名為ROOT.war
