Pass veraiable across different jobs

Actions

As title, how to pass variable across different jobs?

I have tried this one, but no luck with gitea action.

What’s your configuration or workflow file?

3 
name: Build arm64 image
run-name: ${{ gitea.actor }} build invidious.
on:
  workflow_dispatch:
  schedule:
    - cron: "1 1 1 * *" # Every on first day everymonth
  push:
    branches:
      - main
    paths-ignore:
      - LICENCE

jobs:
  build-arm64:
    runs-on: [arm64]
    container:
      image: ${{ secrets.DOCKER_REPO }}/actbuildx:latest

    steps:
      - name: Set RELEASE_DATE
        id: build-arm64
        run: |
          echo "RELEASE_DATE=$(date --rfc-3339=date)" >> ${GITHUB_ENV}
          echo "RELEASE_DATE2=$(date --rfc-3339=date)" >> ${GITHUB_OUTPUT}

  build-multi-architecture:
    needs: build-arm64
    runs-on: ubuntu-latest
    container:
      image: ${{ secrets.DOCKER_REPO }}/actbuildx:latest

    steps:
      - name: Set RELEASE_DATE
        run: |
          set -x
          echo "${{ steps.build-arm64.env.RELEASE_DATE }}"
          echo "${{ needs.steps.build-arm64.env.RELEASE_DATE }}"
          echo "${{ steps.build-arm64.outputs.RELEASE_DATE2 }}"
          echo "${{ needs.steps.build-arm64.outputs.RELEASE_DATE2 }}"

Would you please show us correct example? or any document link?
Thank you.

Did you mean read the output variables of one step from another step? Or you mean global variables?

6

Yes, I want export variable in first job, then read it in second job.
btw, can I export variable as a global variables? (then even read it in other workflow?)

Ok, I found the solution

jobs:
build-arm64:
runs-on: [arm64]
container:
image: ${{ secrets.DOCKER_REPO }}/actbuildx:latest

outputs:
  release_date: ${{ steps.build-arm64.outputs.RELEASE_DATE }}
steps:
  - name: Set RELEASE_DATE
    id: build-arm64
    run: |
      echo "RELEASE_DATE=$(date --rfc-3339=date)" >> ${GITHUB_OUTPUT}

  - name: Get RELEASE_DATE
    run: |
      set -x
      echo "${{ steps.build-arm64.outputs.RELEASE_DATE }}"

build-multi-architecture:
needs: build-arm64
runs-on: ubuntu-latest
container:
image: ${{ secrets.DOCKER_REPO }}/actbuildx:latest

steps:
  - name: Get RELEASE_DATE
    run: |
      set -x
      echo "$RELEASE_DATE"
    env:
      RELEASE_DATE: ${{ needs.build-arm64.outputs.release_date }}
