Version Control · Flashcard
When two steps run in one job, what do they share?
- AOne runner and its filesystem, so files persist between steps
- BNothing at all, since every step is given a runner of its own
- COne shell process, so exported variables survive by default
- DOne log file only, as each step runs on a separate machine
Why this is the answer
A job is a unit of scheduling: its steps run in order on the same runner and workspace, which is why a checkout in step one is still there in step five. Each run: step is nevertheless a fresh shell, so an exported variable is lost unless you write it to $GITHUB_ENV.
