Large amounts of debug output resulting in massive log files in AWS Elastic Beanstalk


I initially brought up this issue on the dev forums:

To sum it up, we run our lucee application in AWS's Elastic Beanstalk service. After upgrading from to, huge log files are being created on the EC2 instance, outside of the docker container. Logging levels are set to ERROR level in the lucee admin console, and none of the tomcat or lucee log files are bloating. Debugging is also turned off in the lucee admin console.

All we do to upgrade Lucee versions is modify the FROM line in our Docker file. This was not an issue with: "FROM lucee/lucee52:". It only became an issue with "FROM lucee/lucee:". My last test with "FROM lucee/lucee:" still contained this logging issue.

The contents of the log files appear to be debug level logging related to the application making external HTTP and/or S3 requests. The reason the files are so large is because they contain the entire file content (images, pdfs, etc) that have been uploaded to the server by users. I have included a sample of a log that has been redacted for senstive info. If you need to see some of the full (very large) logs, let me know and I'll work on cleaning one up.

For now, we have turned the logging off entirely by adding `--log-driver=none` to the `docker run` command in /opt/elasticbeanstalk/hooks/appdeploy/enacts/ This is just a temporary solution because we have to keep adding it manually every time Elastic Beanstalk spawns a new EC2.

If I had to guess, there is some sort of console output that Elastic Beanstalk is picking up and logging. We've run into similar issues in a separate Node.js application where every `console.log()` left behind in the application code was being picked up in log files and eventually eating up all of the disk space of the EC2 instance.

Sample log file, named something like /var/log/eb-docker/containers/eb-current-app/eb-063d69495c9f-stdouterr.log:
