Explanation:
The --project flag allows overriding the project for a single command without changing the default configuration. Changing config affects all subsequent commands, and re-authenticating or editing config is unnecessary.
You run gcloud compute instances list and get instances from the wrong project. What's the fastest way to target project web-prod for just this one command?
A
gcloud config set project web-prod then rerun
B
Add --project=web-prod to the command
C
gcloud auth login
D
Edit ~/.config/gcloud
