docker -t devguides/hello-world:latest .

docker push devguides/hello-world:latest

Add Additional Tags to Your Docker Image

You often want to include tags like version in addition to the latest tag. To add a version tag you write the following commands:

docker tag devguides/hello-world:latest devguides/hello-world:1.0.0
docker push devguides/hello-world:1.0.0

The commands above will create a version tag called 1.0.0 and push the tag to Docker Hub.
