I have a Selenium Python (3.9) renderer script that will perform a bunch of fetching tasks that I'm trying to utilize a AWS EC2 virtual machine for a runtime on the cloud. I am running it by using SSH to access the VM, adding the scripts and dependencies, and then running it with a python3 <script-name>.py.

But, I need help preserving the runtime instance till my script is completely (or indefinitely till I manually delete the instance). Currently, the script seems tied to my local CLI, and when I leave it be for a while or shut my lid, the AWS VM runtime quits with error:

Client Loop: Send Disconnect: Broken Pipe

How can I preserve the runtime indefinitely or till end of script, and untie it from any local runtimes? Apologies for any idiosyncrasy, I'm new to DevOps and deploying stuff outside of local runtimes.

I used ClientAliveInterval=30, ServerAliveInterval=30, ClientAliveCountMax=(arbitrarily high amount), and ServerAliveCountMax=(arbitrarily high amount). I tried to use nohup inside my VM, but it did not prevent the process from ending. I have observed that when ps -a returns my ssh session, it is running, else it is not.

I am using a M1 Mac on Ventura. The AMI I am using to create the VM is ami-08e9419448399d936. This is Selenium-Webdriver-on-Headless-Ubuntu, using Ubuntu 20.04.

  • Use something like [screen or nohup](https://stackoverflow.com/questions/20766300/nohup-vs-screen-which-is-better-for-long-running-process) to run the script in the background. – Anon Coward Jan 14 '23 at 16:47
