I have a project-level environment variable defined with the value X .
During pipeline execution, given a given condition, I need to change the value of this variable to Y .
The value must be persisted in the variable so that in the next run the pipeline uses the value Y and not the X .
Is it possible? If so, how?
Note: I will not post the code of my .gitlab-ci.yml because I could not evolve anything regarding this subject, so I would not add in the question.
