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 }}"

For anyone seeing this,
this echo "::set-output ..." syntax won't work when run from inside a script
example :

# sample.sh
echo "::set-output name=ip-address::$(curl -s ifconfig.me)"

# workflow
  steps:
      - name: step-1
        id: xyz
        run: source sample.sh
      - name: step-2
        run: echo "${{ steps.xyz.outputs.ip-address }}"

This will fail to ::set-output

is there a way to solve it?

maybe set the value as an environment variable

run: echo "ip_address=$(curl -s ifconfig.me)" >> $GITHUB_ENV

and access it, anywhere using

run: echo IP Adress is: ${{ env.ip_address }}

For people finding this: "::set-output" does work within a script; you don't have to put it in the action YAML. (It's possible GitHub has changed something since the comment above saying the opposite, but I just tried it and it worked for me.)
