Question

我有一个grails应用程序，已经运行并通过Tomcat8 Jre8上的Elastic Beanstalk部署到AWS。

我现在正试图在多Docker环境中部署它，我有很奇怪的行为。

我使用tomcat:8.0-jre8（https://hub.docker.com/r/library/tomcat/）作为容器的图像，并且通过在<tomcat_home>/webapps中放置war文件，该图像上的部署非常简单。另外，我将端口8080映射到外部世界。所以，docker-compose的相关部分看起来像这样：

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

根据日志，应用程序已成功部署，甚至liquibase迁移正在应用：

21-Nov-2016 07:11:03.671 INFO [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployWAR Deploying web application archive /usr/local/tomcat/webapps/priz-0.5.war

Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

但是，当我尝试访问任何一个现有端点时，我得到了404。

现在，同样基于日志，请求实际上是在命中服务器：

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

我如何解决这个问题怎么调试呢？我错过了什么？日志中没有什么特别之处。

此外，我尝试了不同版本的tomcat，包括在AWS EBS上运行的完整版本。此外，尝试通过nginx代理请求，结果相同。

你的战争文件名是priz-0.5.war。因此上下文名称也是priz-0.5。你必须打电话给例如http://localhost:8080/priz-0.5

如果您想将其称为http://localhost:8080/，只需将war-File重命名为ROOT.war

部署WAR到tomcat docker容器后总是得到404
