How to get the output of container_commands after deployment?

  • 772

My Elastic Beanstalk container uses container_commands to run a script to patch the database on every deployment.

I run the deployments with a home-brewed script that calls the UpdateEnvironment on the Elastic Beanstalk API.

The problem is, I have no visibility on the output of my container_commands, which is pretty scary during deployment. The only way I can tell if something went wrong is when a command returns a non-zero value: in that case DescribeEvents will report a problem. But still, I have no way to get the actual output of the command.

How can I get my container_commands output after the deployment has finished?

Ideally, with the Elastic Beanstalk API, but any other programmatic way will be fine!

  1. Not a console view, but it is (now) visible in the logs.

    .ebextensions/10-log.config

    container_commands:
  05-whoami:
    command: "whoami"

    /var/log/cfn-init.log after deployment

    Reply from the AWS support:

    The easiest way to see the output would be to pipe the command or script output to a file using >>. Unfortunately there isn't a live console that can be viewed to show the process live.

    So unfortunately there is no way to do that (yet).
