fail step #5912
Description
Note: If you're requesting a Helm chart option that may be very niche and not useful to the community at large, please consider using Kustomize to apply "last mile" tweaks to the output of helm template to suit your needs instead.

Proposed Feature
If you want to be able to fail a promotion task based on an expression evaluation, there doesn't appear to be a good way to do that at the moment. You can kind of do it by misusing the http step, pointing it to an invalid url and using the failureExpression to do the evaluation, kind of like this:
steps:
- uses: http
config:
url: https://url.that.doesnt.exist
successExpression: true
failureExpression: expressionThatWillFailPipelineIfTrue
Instead if we had a step what always failed, we could use conditional step execution, avoiding the http request:
steps:
- uses: fail
if: ${{ expressionThatWillFailPipelineIfTrue }}
Motivation
It may be necessary to fail the pipeline based on freight/chart/http outputs, this gives us a clear tool for doing so
Happy to work on this if it gets approved :)
