tomcat - 将 WAR 部署到 tomcat docker 容器后总是得到 404

Question

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

我现在正尝试将它部署在多 docker 环境中，但我的行为很奇怪。

我正在使用 tomcat:8.0-jre8 ( https://hub.docker.com/r/library/tomcat/ ) 作为容器的镜像，在该镜像上的部署非常简单，只需在 <tomcat_home>/webapps 中放置一个 war 文件即可。 .另外，我正在映射端口 8080到外面的世界。因此，docker-compose 的相关部分如下所示:

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

根据日志，应用已成功部署，甚至应用了 liquibase 迁移:

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，我收到 404 返回。

现在，同样基于日志，请求实际上正在发送到服务器:

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

我该如何处理这个问题，如何调试它？我错过了什么？日志中没有什么特别的。

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

您的 war 文件名为 priz-0.5.war。所以上下文名称也是 priz-0.5。例如，您必须调用 http://localhost:8080/priz-0.5

如果你想像 http://localhost:8080/ 那样调用它，只需将 war-File 重命名为 ROOT.war
