This is because I only installed docker in my Ubuntu and don't have docker desktop.

Deleting below line

"credsStore": "desktop",

from ~/.docker/config.json can fix this issue.

The final argument right at the back of the Docker build command from the preceding is not a typo. That is an important argument that is needed to indicate the folder, which we would use as a reference for the Dockerfile to build it from. In most
cases, Dockerfiles tend to be at the root of subprojects, and the current symbol of “.” indicates the current directory is usually the correct parameter to use in most cases.
