GitHub Actions example workflow — Outputs 2

09-outputs-2.yml

name: outputs-2
on: workflow_dispatch
jobs:
  my-job:
    runs-on: ubuntu-latest
    steps:
      - name: step-1
        id: xyz
        run: echo "::set-output name=ip-address::$(curl -s ifconfig.me)"
      - name: step-2
        run: echo "${{ steps.xyz.outputs.ip-address }}"

"::set-output" is supposed to still work, but its deprecated. Blog post about how to migrate, which is essentially @mraarif's answer above: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/
