Elastic Beanstalk with Docker deployment failure

Question

I'm trying to deploy my application with docker and elastic beanstalk. My Dockerrun.aws.json file looks like

{
  "AWSEBDockerrunVersion": "1",
  "Image": {
    "Name": "jvans/maven_weekly",
    "Update": "true"
  },
  "Ports": [
    {
    "ContainerPort": "5000"
  }],
  "Volumes": [
    {
      "HostDirectory": "/Users/jamesvanneman/Code/maven_weekly/maven_weekly",
      "ContainerDirectory": "/maven_weekly"
  }
  ],
  "Logging": "/var/log/nginx"
}

I created this application with eb create and when I run eb deploy I get

Docker container quit unexpectedly after launch: Docker container quit 

unexpectedly on Mon Sep 21 01:15:12 UTC 2015:. Check snapshot logs for details. 
Hook /opt/elasticbeanstalk/hooks/appdeploy/enact/00run.sh failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.

In var/log/eb-activity.log I see the following errors:

  Docker container quit unexpectedly after launch: Docker container quit unexpectedly on Mon Sep 21 01:08:52 UTC 2015:. Check snapshot logs for details. (ElasticBeanstalk::ExternalInvocationError)
caused by: 83ea9b7f9a069eeb8351fef7aaedb8374f7dfe300a5e0aaeba0fe17600583175
[2015-09-21T01:08:52.205Z] INFO  [2246]  - [Application deployment/StartupStage1/AppDeployEnactHook/00run.sh] : Activity failed.

So it seems like there's a problem with a startup script. If i ssh into the container and try to run it manually I don't really get any extra help from error messages.

eb ssh

sudo /opt/elasticbeanstalk/hooks/appdeploy/enact/00run.sh

Docker container quit unexpectedly after launch: Docker container quit unexpectedly on Mon Sep 21 01:34:52 UTC 2015:. Check snapshot logs for details.
Msg: Docker container quit unexpectedly after launch: Docker container quit unexpectedly on Mon Sep 21 01:34:52 UTC 2015:. Check snapshot logs for details.

Are snapshot logs something different than what's in var/log/eb-activity.log? Any Idea what is going on/how I can debug this further?

Answer 1

Docker dumps are stored in the host box at /var/log/eb-docker/containers/.
Go there and you'll find the docker startup crash log that should indicate the root cause of your problem.

Answer 2

You want to look at

/var/log/eb-docker/containers/eb-current-app/unexpected-quit.log

in the bundle downloaded by eb logs --all or using eb ssh. This log file will have the stdout and stderr of your application before it crashed.
