How do I push the docker image to dockerhub? I use docker push <myuserid>/hellodocker. This gives a 'no such id` error. What am I missing? Thanks in advance.
You either need to tag it as <myuser>/hellodocker when you build it, e.g.
docker build -t <myuser>/hellodocker:mytag .
or create a new tag tied to the same image, i.e.
docker tag hellodocker:mytag <myuser>/hellodocker:mytag
