when building docker image, "no basic auth credentials"

> To build the docker image, call `docker build .`.

When trying to build the image, this is what I get:
```
Sending build context to Docker daemon  1.631MB
Step 1/11 : FROM griffig.xyz/base
Head "https://griffig.xyz/v2/base/manifests/latest": no basic auth credentials
```
The build process stops there.
