It will also build `linux/amd64,linux/arm64` which you can override with `PLATFORMS`.

You can also build a set of images instead of all of them:

```bash
docker buildx bake --push examples-helloworld-v1 tcp-echo-server
```

## Updating images

When updating images, increment the version for the image in the `tags` config.
You will also want to update the sample YAMLs
