condition to run task with dependence

In gitlab ci pipeline, I know how to set the dependency between stages.

deploy:
  stage: deploy
  needs: [iac]
  ...

I also know to set filter,

iac:
  stage: iac
  only:
    changes:
      - iac/*
  ...

But how to set the dependency and filter together. The conditions are:

stage iac: if any files under folder iac are changed, need run this stage, if no change, skip

stage deploy: depends on stage iac ,

But when stage iac is skipped (no change), the pipeline will be confused.

'deploy' job needs 'iac' job, but 'iac' is not in any previous stage

Your deploy stage is looking for iac stage evrytime, you need to apply the same rules to both stages. You can use the rules keywords because :

only and except are not being actively developed. rules is the preferred keyword to control when to add jobs to pipelines.

So you can define a global rule and extends it to the jobs you want to filter :

.rules:iac-changes:
  rules:
    - changes:
      - iac/*

deploy:
  stage: deploy
  extends:
    - .rules:iac-changes
  needs: [iac]
  ...

iac:
  stage: iac
  extends:
    - .rules:iac-changes
  ...

If you want to run the deploy stage anyway, you can make the needs optional.
