Are there cases where an exitcode other than 1 is returned in case of an error?

Terraform

hi, team.
I want to set up CI/CD so that it will automatically deploy when I apply terraform.
However, it seems like the only return values ​​you can check are 0 or 1. Are there any others?

Looking at the source code, it seems that only fmt.Errorf() is executed in the event of a failure, but what is the most efficient way to prevent the apply judgment from being made in the event of a failure?

When successful, it appears to determine that the result is true using a method similar to grep -q, but if there is any other source code I should look at, please let me know.

I would not try to overthink / overcomplicate it. You should treat 0 as success and anything other than 0 as failure.

If you can, either use a tool that will already handle this for you (like a CI tool, or tools designed for running Terraform in a pipeline, like Atlantis), or use a shellscript and set -e and -o pipefail in it.

In other words, unless there’s a very good reason you have to, don’t try to catch the exit code and do something with it; let the CI tool you’re using fail in the event that the exit code is not 0.
