Ruby beanstalk platform can't run /opt/elasticbeanstalk/bin/get-config

Question

We recently upgrade two apps to ruby 2.4 (Puma with Ruby 2.4 running on 64bit Amazon Linux/2.11.1) and 2.6 (Puma with Ruby 2.6 running on 64bit Amazon Linux/2.11.0), but it looks like we can't run /opt/elasticbeanstalk/bin/get-config anymore.

Seems like probably a bug in the platform. Is there any workaround available?

Thanks!

Answer

Looks like this sort of works around running the tool, but the metadata key we used to use seems to have changed

```
 sudo bash -c 'GEM_PATH=/opt/elasticbeanstalk/lib/ruby/lib/ruby/gems/2.2.0 /opt/rubies/ruby-2.2.10/bin/ruby /opt/elasticbeanstalk/lib/ruby/bin/get-config meta -k sqsdconfig'
Path AWS::ElasticBeanstalk::Ext||_SqsDaemonConfigFileContent doesn't exist in metadata.
```

Slightly off of the topic, but is there a recommended way to find out the SQS visibility timeout in a worker env?  
  
The whole usage of get-config was to find that out so we can adjust the nginx timeout to match:

```
commands:
  match_nginx_timeout_to_sqs_timeout:
    command: |
      # If worker tier set nginx timeout to SQS visibility timeout
      if /opt/elasticbeanstalk/bin/get-config meta -k sqsdconfig 2>/dev/null; then
        VISIBILITY_TIMEOUT=$(/opt/elasticbeanstalk/bin/get-config meta -k sqsdconfig | jq -r .visibility_timeout)
        echo "proxy_read_timeout ${VISIBILITY_TIMEOUT}s;" > /etc/nginx/conf.d/worker.conf
        service nginx restart
      fi
```

Otherwise nginx can timeout too early and cause worker job retries (and pileup of jobs)

Looks like I figured it out. `/opt/elasticbeanstalk/bin/get-config meta -k sqsdconfig` still works just only as root (not ec2-user like I was trying)  
  
And the missing `Path AWS::ElasticBeanstalk::Ext||_SqsDaemonConfigFileContent doesn't exist in metadata.` was due to what should have been a worker tier env having been started as a web tier.
