调试Elastic Beanstalk Docker运行失败？

Question

我是EB和AWS的新手,我的docker图像构建正常,但无法在Elastic Beanstalk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 logs"时,我没有得到任何有用的东西.以下是错误:

{
  "status": "FAILURE",
  "api_version": "1.0",
  "results": [
    {
      "status": "FAILURE",
      "msg": "(TRUNCATED)...rrun.aws.json: No such file or directory

          "timestamp": 1432142064
        },
        {
          "msg": "Successfully built aws_beanstalk/staging-app",
          "severity": "TRACE",
          "timestamp": 1432142094
        },
        {
          "msg": "Docker container quit unexpectedly after launch: Docker container quit unexpectedly on Wed May 20 17:15:02 UTC 2015:. Check snapshot logs for details.",
          "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弄清楚出了什么问题？我一直听说"快照日志",但我在哪里查看这些快照日志？它们是我已经运行"eb日志"的输出吗？

Answer 1

我遇到这个问题有一两天了。我设法通过转到 AWS Console > Elastic Beanstalk > 环境 > ${YOUR_APPLICATION_ENV} 查看日志

在左窗格中；

日志 > 请求日志 > 下载 > 在任何文本编辑器中打开。

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

按照路径操作，您将看到导致错误的原因并可以修复它。

当我的容器崩溃时，我遇到了这个问题，因为 EBS 和 RDS 之间不允许有流量。如果您使用任何数据库，请尝试卷曲它。另外，您可能想尝试sudo docker logs CONTAINER_ID捕捉一些有用的东西。尝试从实例手动启动容器也可能有帮助。有轻微的可能性会发生一些事情。
