Where does elastic beanstalk t2 server store my node.js app files?

Question

From an architecture perspective, I'm trying to get a better understand of how and where files deployed to eb (t2) server are stored.

I see some .zip files in s3 that show when I upload something via the eb interface, though how/where exactly does this get end up on my ec2(t2) server?

Answer 1

It's within the /tmp/deployment/application folder during deployment and then moved to /var/app/current subsequently.

In case you search them, the node logs are in /var/log/nodejs/nodejs.log and therefore the application can bind to 8081 regardless of what PORT environment variable you set within the Environment Variables in the console.
