The changes to MAXCHECKS seem unnecessary? MAXCHECKS should be evaluating to the proper value in those bash arithmetic expressions without the $. Are you seeing differently?

No it's not necessary. I was trying a few different things to see what's causing the failure.

Looks like when you upgraded ubuntu to 22.04, docker start to use cgroupv2, that cause that /proc/${PID}/cgroup is containing only 0::/, so spire is unable to get container ID,
in order to have a success upgrade we must address #4004

I'm working on #4004 this week.

@faisal-memon can you remove unnecessary changes (changes related with testing why it was failing) and resolve DCO?

[azdagron]

Integration tests are now passing, @faisal-memon. Feel free to just squash my commits in with your other edits when you fix DCO.

Backed out all the unnecessary changes

Thanks @faisal-memon. I think you need to re-introduce one change (shellcheck is complaining during linting). Afterwards feel free to squash the changes, fix up DCO, and force-push. I'll re-review the final change and then we can get this merged!
