docker under macOS: cannot run

Under macOS 10.13.6 I installed current stable version of Docker, opened Docker.app, signed in there, created ~/Documents/webwork_docker, cd'd to that folder, and then in Terminal attempted to execute:

docker run -d -p 80:80 --name webserver nginx

This gave error:

Unable to find image 'nginx:latest' locally

docker: Error response from daemon: Get https://registry-1.docker.io/v2/library/nginx/manifests/latest: unauthorized: incorrect username or password.

See 'docker run --help'.


In fact, I get a similar error just trying to execute:

docker run hello-world


Any idea how to fix this?
