Local disk resource

Problem: I have a pipeline that includes a "build and deploy" task, like so:

- name: build-deploy
  plan:
  - get: my-repo
    trigger: true
    passed: [test]
  - task: build-artifact
    file: my-repo/ci/build.yml
  - put: ecr-repository
    params:
      build: my-repo-output
      tag: my-repo-output/version

Now I want to split this into two tasks, so I can build once and possibly deploy (or use artifacts in other ways) multiple times. Problem: the output directory does not survive across tasks. I can use an S3 bucket or something like that to persist the artifact across builds, but that's a pretty big detour to cache some files between tasks.

It would be very convenient if there was a "local disk resource" that I could put outputs in and get in other tasks in the pipeline. Does something like this exist?

To clarify, I don't want to use S3 for a few reasons:

• Requires configuration of additional keys
• Network penalty in ever task using it
• Retains artifacts that I don't really need
