+# ecr-build-push-pull
+
+Builds a Docker image and pushes it to ECR, or pulls it if the tag already exists.
+ECR is also used as the BuildKit layer cache.
+
+## Usage
+
+```yaml
+- uses: ./.github/actions/ecr-build-push-pull
+  with:
+    image-tag: ${{ env.DOCKER_IMAGE_TAG }}
+    isaacsim-base-image: nvcr.io/nvidia/isaac-sim
+    isaacsim-version: 6.0.0
+    dockerfile-path: docker/Dockerfile.base
+    cache-tag: cache-base
+    ecr-url: (optional, complete url for ECR storage)
+```
+
+## ECR URL resolution order
+
+1. `ecr-url` input
+2. `ECR_CACHE_URL` environment variable on the runner
+3. SSM parameter `/github-runner/<instance-id>/ecr-cache-url`
+4. If none resolve, ECR is skipped and the image is built locally
