 In essence, a `docker_builder` is basically [a `task`](writing-tasks.md) that is executed in a VM with pre-installed Docker. 
 A `docker_builder` can be defined the same way as a `task`:
 
-```yaml
-docker_builder:
-  build_script: docker build --tag myrepo/foo:latest .
-```
+=== "amd64"

+    ```yaml

 Under the hood a simple integration with [Google Compute Engine](supported-computing-services.md#compute-engine)
