Use environment variable in github action if

I'm trying to use an environment variable in an if condition in github actions like so:

name: Worfklow
on:
  push

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1

      - name: EXIT step
        if: $GITHUB_REF == 'specific-branch'
        run: exit 1

I want to exit if the current branch is equal to a specific branch.

Unfortunately, the github actions console displays an error:

Unexpected symbol: '$GITHUB_REF'

I can use $GITHUB_REF in a run: (where it contains the current branch), but not in an if:. What am I doing wrong?

Solution

  • do it like this:

    if: github.ref == 'specific-branch'

    reference branch conditional
