Not everything on the net can be pinged; that’s not necessarily a problem. The docker CLI knows how to contact DockerHub automatically, so you need to:

  • Use docker login to present your credentials to the CLI
  • Tag your image as DOCKER_USERNAME/YOUR_IMAGE_NAME:IMAGE_TAG.
  • Push the image with docker push DOCKER_USERNAME/YOUR_IMAGE_NAME:IMAGE_TAG, which should push your image from your local docker server to DockerHub.

i log in using : docker login -u username , and pushed with docker push DOCKER_USERNAME/YOUR_IMAGE_NAME:IMAGE_TAG. thank you sir
