I'm trying to push my docker image up into the public docker registry:

$ docker login Username (binarybana):  WARNING: login credentials saved in /home/jknight/.dockercfg.

[Y/n]: Y The push refers to a repository [docker.io/binarybana/fedora-dev] (len: 0) FATA[0002] Repository does not exist: docker.io/binarybana/fedora-dev

Yet, I've already created the repository (viewable here). And I've also tried to push to repository names that I haven't already created (the first try in the example above).

I think the (len: 0) has something to do with it, but I can't google it. Also I originally created the image from a dockerfile as:

docker build -t binarybana/fedora-dev .

Thanks.

How do I push an image to Docker Hub public repository?

To push an image to Docker Hub, you must first name your local image using your Docker Hub username and the repository name that you created through Docker Hub on the web. You can add multiple images to a repository by adding a specific :<tag> to them (for example docs/base:testing ).

Does docker build push to registry?

The built image is then pushed to the Docker Hub registry. You can still use docker push to push pre-built images to repositories with Automated Builds configured. If you have automated tests configured, these run after building but before pushing to the registry.

Always build your image with "username" and "tag"

docker build -t <username>/dev-fedora:latest .

After building push the image

docker push <username>/dev-fedora:latest
