docker push 403

A "docker push 403" error occurs when you try to push a Docker image to a Docker registry, but you do not have permission to do so. This error is usually caused by one of the following reasons:

1. Authentication failure: You may not have the correct credentials to access the Docker registry. Make sure you have logged in to the registry using the correct username and password.

2. Permission denied: The Docker registry may not have given you the necessary permissions to push images. Check with the registry owner to see if you have the required permissions.

3. Incorrect Docker configuration: Your Docker configuration may be misconfigured, causing the push to fail. Check your Docker configuration settings to make sure they are correct.

To fix the "docker push 403" error, you may need to check your Docker configuration, ensure you have the correct credentials, or contact the Docker registry owner to request permission to push images.
