why don`t make step as a kind of resource,just like task,pipeline, so we can use step at anywhere too.

@gitupxm163 There is actually an open issue for this (#1260). I unfortunately never got around to putting together a proposal for it, but there has been some activity around it if you would like to weigh in on the discussion. I think the original thought process when creating Tekton would be that Tasks would be the easiest way to reuse resources as mentioned in the issue. However, I also see the validity in making steps reusable via some type of ref property. Please feel free to add any use cases or ideas you have in the original issue.

@gitupxm163 @danielhelfand trying to understand the use case and the value this would add. Will your use case suffice by creating a script and reusing it:

steps:
- image: ubuntu
  script: |
    #!/usr/bin/env bash
    /workspace/path-to-script/my-script.sh 

Here, my-script.sh can be part of the GitHub repo and the repo is cloned into workspace using git-clone.

I'm going to close this as a duplicate of #1260.

@pritidesai I think the main issue is the design of Tekton itself is supposed to promote reusability, and yet step properties need to be fully written out as part of a Task instead allowing them to be easily shared a reused.

Why should a user need to define this step's image, command or script, resource requests/limits, securityContext, etc. again if a step already exists and has these properties defined? I think steps should somewhat mirror the design of Tasks in that they should be able to accept values at run time and be easily shared via a ref property. It's really in my mind about promoting DRY and reducing copy and paste as a practice for reusing steps.

That and the ability to easily define a step that runs a script or quick command without having to create a whole Task definition would also be interesting.
