Can I run a command before the 'earlier' steps of a CircleCI job?

The earlier steps are I am referring to are “Starting the build”, “Start container”, and “Enable SSH”.

I’m wanting to run my own command before one of those.


curl -X POST -F 'build=$CIRCLE_BUILD_NUM'

I’m hoping there’s some corner of circle.yml that I’m not aware of yet :slight_smile:
