    First encountered this error myself in step 4 of the hands-on lab for week 2 of the introduction to containers course.

    this line:
    ```
    docker build -t us.icr.io/$MY_NAMESPACE/hello-world:1 . && docker push us.icr.io/$MY_NAMESPACE/hello-world:1
    ```

    errors out with
    ```
    invalid argument "us.icr.io/sn-labs-/hello-world:1" for "-t, --tag" flag: invalid reference format
    See 'docker build --help'.
    ```
