# "Get Docker Image Label" Github Action

This Github action inspects a given Docker image and returns the value

of a specified label.

Consider a Docker image tagged as "flownative/php:7.4". This image

contains a label "org.label-schema.version" in its metadata which tells

the full PHP version number "7.4.4". Using this action, you can retrieve

this version number for further processing in your workflow.

## Example workflow

````yaml

# …

jobs:

  build:

    runs-on: ubuntu-latest

    steps:

# …

      - name: Determine latest version

        id: latest_php_version

        uses: flownative/action-docker-get-label@v1

        with:

          image: flownative/php:7.4

          label: org.label-schema.version

          registry_username: github

          registry_password: ${{ secrets.GITHUB_BOT_TOKEN }}

          registry_endpoint: https://docker.pkg.github.com/v2/

      - name: Build Docker image

        uses: flownative/action-docker-build@v1

        env:

          PHP_VERSION: ${{ steps.latest_php_version.outputs.value }}
