Can I pause or cancel a circle ci build based on environment variable in config.yml?

Build Environment
1

I need to skip a build from running it.
Suppose there is a env variable in circleci environment CANCEL_BUILD=true
if it is “true”, I need to cancel the build. I do not want to show a failure status because of the cancellation. I want the build status to be cancelled or stopped.

Any help would be appreciated.

See if https://support.circleci.com/hc/en-us/articles/360015562253-Conditionally-End-a-Running-Job-Gracefully is what you’re looking for.

Do you want to skip the entire pipeline?

If so, merging with [skip ci] or [ci skip] would be my first suggestion, if it works for your use case.
