# Docker image ID

A Github action to retrieve the image id for an image name.

This is useful if you want to check if images have been updated (comparing new vs old id). Mostly in case of images that are being used as base image in your image and you would like to re-create your image if the base image has changed.

## Usage

```yml

  - name: Image ID

    id: image-id

    uses: s3vt/docker-image-id@v1.0.0

    with:

      image_name: "s3vt/java:18"

```

This can be used in sample projects as 

```yml

on:

  push:

jobs:

  image-query:

    runs-on: ubuntu-latest

    name: Get Image ID

    steps:

      - name: Image ID

        id: image-id

        uses: s3vt/docker-image-id@v1.0.0

        with:

          image_name: "s3vt/java:17"

      - name: Print the image ID

        run: echo "Image ID is ${{ steps.image-id.outputs.image_id }}"

     

```
