 1. Both are eventually calling `make release`, so environment must be different.

 1. A few directions we could go here:
     1. Update the `k8s-ci-builder` image to you use newer version of Docker
     1. Update the `k8s-ci-builder` image to ensure that
-       `DOCKER_CLI_EXPERIMENTAL=enabled` is set
+`DOCKER_CLI_EXPERIMENTAL=enabled` is set
     1. Update the `release.sh` script to set `DOCKER_CLI_EXPERIMENTAL=enabled`
 
 1. Making the `release.sh` script more flexible serves the community better
-   because it allows for building with more environments. Would also be good to
-   update the `k8s-ci-builder` image for this specific case as well.

 1. Job turns green! But how?
 1. [Buildx](https://github.com/docker/buildx) is versioned separately than
