Get the current pushed tag in Github Actions

Question

Is there a way to access the current tag that has been pushed in a Github Action? In CircleCI you can access this value with the $CIRCLE_TAG variable.

So thanks to all the help from @peterevans I managed to achieve the result I wanted which was:

• to tag a commit
• push the tag to trigger the github action
• github action sets the git tag as an env var
• run install & build
• use chrislennon/action-aws-cli action to install aws cli using secrets for keys
• run command to sync the build to a new S3 bucket using the tag env var as the dir name

Here is an example of the what I ran using Chris Lennon's action:

on:
  push:
    tags:
      - 'v*.*.*'
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - name: Set env
        run: echo ::set-env name=RELEASE_VERSION::$(echo ${GITHUB_REF:10})
      - name: yarn install & build
        run: |
          yarn install
          yarn build
      - uses: chrislennon/action-aws-cli@v1.1
      - name: Publish to AWS S3
        env:
          AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
          AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          AWS_S3_BUCKET: ${{ secrets.AWS_S3_BUCKET }}
        run: aws s3 sync dist s3://$AWS_S3_BUCKET/$RELEASE_VERSION/ --acl public-read
