Apply failed halfway. What happens to the half that worked?

You'll learn to
apply a change or a saved plan, use -auto-approve and -replace, and say what happens on a partial failure
Recap
- 1apply = a fresh plan + your yes. -auto-approve only behind a review
- 2terraform apply tfplan runs a saved plan exactly; a stale plan is refused
- 3-replace=ADDRESS rebuilds one thing. No rollback: fix and apply again
