I've been facing a couple of issues with the Python subprocess library while trying to run some bash commands. The strange part is that my host OS is CentOS 7, and I'm using Ubuntu 22.04 in my Docker container. Could the differences in operating systems be causing these issues? I feel like they shouldn't, theoretically, but I'm not so sure anymore.

If you can, it might be worth considering running a CentOS container instead of Ubuntu. It could help reduce potential compatibility issues since your host is CentOS. But if your boss insists on using Ubuntu, then you've got to work with that!
There's a lot that could be going wrong here. While it's unlikely that the different OS versions are the root cause, there could be specific library dependencies or conflicts within the container. It’s pretty rare for that to be the issue since containers are made to isolate these kinds of problems, though!
Honestly, it's hard to pinpoint the exact problem. But typically, the host OS and the container OS shouldn't interfere with each other. If you're running Ubuntu in Docker, it should work independently of your CentOS host.
Yeah, I get where you're coming from. I've had a similar experience with a Spring MVC project that requires Java 8. I set it up on an Ubuntu server and ran it inside a Docker container, and everything worked great. But after I ran an `apt upgrade`, the project wouldn't start anymore due to library conflicts. Now, I just skip that upgrade because it causes too many headaches!
