 # github-common-actions
 Reusable composite actions used from other Weaviate workflows to avoid code duplication
+
+## weaviate-version-in-image
+
+### Description
+Retrieves the Weaviate version from a given Weaviate Docker image.
+
+### Inputs
+- `image_tag` (required): The Weaviate Docker image to retrieve the version from. Default: `latest`.
+- `registry` (optional): The Docker registry and namespace to pull the image from. Default: `docker.io/semitechnologies/weaviate`.
+
+### Usage
+```yaml
+name: Retrieve Weaviate Version
+on: [push]
+
+jobs:
+    retrieve-version:
+        runs-on: ubuntu-latest
+        steps:
+            - name: Checkout repository
+                uses: actions/checkout@v2
+
+            - name: Retrieve Weaviate Version
+                uses: ./.github/actions/weaviate-version-in-image
+                id: weaviate-version
+                with:
+                    image_tag: 'latest'
+                    registry: 'docker.io/semitechnologies/weaviate'
+
+            - name: Output Weaviate Version
+                run: echo "Weaviate Version: ${{ steps.weaviate-version.outputs.weaviate_version }}"
+```
+
+### Runs
+This action runs using `composite` with the following steps:
+1. **Set globals**: Sets global variables for action timeout and port.
+2. **Start Weaviate service**: Starts the Weaviate Docker container.
+3. **Wait for .well-known/ready API to be ready**: Waits until the Weaviate service is ready.
+4. **Set the Weaviate version as an output**: Retrieves and sets the Weaviate version as an output.
