The following command creates both for "testuser" with password "testpassword".

```console
$ docker run --rm --entrypoint htpasswd registry:2 -Bbn testuser testpassword > auth/nginx.htpasswd
$ docker run --rm --entrypoint htpasswd httpd:2.4-alpine -Bbn testuser testpassword | tee -a auth/nginx-ro.htpasswd auth/nginx-rw.htpasswd > /dev/null
```
