调试弹性Beanstalk Docker运行失败？

我是EB和AWS新手，我的docker图像构建良好，但无法在弹性豆茎上运行。我怀疑他们没有正确连接到数据库，但是，当我从命令行运行“eb日志”时，我没有得到任何有用的东西。以下是错误：

{

  "results": [

        },
        {

          "severity": "ERROR",
          "timestamp": 1432142102
        }
      ]
    }
  ],
  "truncated": "true"
}

构建完成后：

docker容器在本地工作，那么我还能做些什么来找出哪里出了问题？我一直听说“快照日志”，但我在哪里检查这些快照日志？它们是我正在运行的“eb日志”的输出吗？

当我的容器崩溃时，我遇到了这个问题，因为EBS和RDS之间不允许通信。如果您使用任何数据库，请尝试将其卷曲。此外，您可能希望尝试

sudocker logs CONTAINER\u ID

a尝试捕获有用的内容。还可以帮助您尝试从实例手动启动容器。有一点可能会出现问题。

假设您对运行容器的EC2实例具有SSH访问权限，以下是一些日志文件，可用于调试Beanstalk中的单个容器Docker实例：

• /tmp/docker_build.log
• /tmp/docker_pull.log
• /tmp/docker_run.log

为了查看正在运行的进程的错误日志，首先读取 /tmp/docker_run.log文件。此文件包含Docker进程id。类似以下内容：

c6ae58e4ad77e926f6a8230237acf95771c6b5d80d48fb1bc20591f964fd690c

前几个字符应与命令

docker ps

中列出的进程匹配。使用此值在以下目录中查找相应的日志文件：

/var/log/eb docker/containers/eb current app/

---

文件名的格式是eb-docker ps id-stdouterr.log

您的项目中是否有Dockerrun.aws.json文件？如果您有DockerFile，您不应该需要Dockerrun.aws.json…如果您可以ssh到ec2实例上，您是否知道如何读取日志，然后，您可以使用

sudo docker ps-a

找到容器id，然后运行

sudo docker log

。主机上的日志也位于

/var/log/eb docker/containers/
