Could someone explain why it would be beneficial to record the CIRCLE_SHA1
when checking out the code from Github and cache it?
version: 2
jobs:
checkout_code:
docker:
- image: circleci/node:latest
working_directory: ~/my-project
steps:
- checkout
- attach_workspace:
at: ~/my-project
- run: echo $CIRCLE_SHA1 > .circle-sha
- save_cache:
key: v1-repo-{{ .Branch }}-{{ checksum ".circle-sha" }}
paths: .circle-sha
- persist_to_workspace:
root: .
paths: .
