github actions outputs

The following workflow provides an example of using outputs. step1 generates the outputs. The name is defined by the outputs in job1. 

Then job2 refers to it using job1.outputs.output1.  needs is use to define dependencies between jobs.

jobs:

  job1:

    runs-on: ubuntu-latest

    # Map a step output to a job output

    outputs:

      output1: ${{ steps.step1.outputs.test }}

      output2: ${{ steps.step2.outputs.test }}

    steps:

      - id: step1

        run: echo "test=hello" >> "$GITHUB_OUTPUT"

      - id: step2

        run: echo "test=world" >> "$GITHUB_OUTPUT"

  job2:

    runs-on: ubuntu-latest

    needs: job1

    steps:

      - env:

          OUTPUT1: ${{needs.job1.outputs.output1}}

          OUTPUT2: ${{needs.job1.outputs.output2}}

        run: echo "$OUTPUT1 $OUTPUT2"

       

After running, the output will be "hello world" as shown in diagram below:
