"The push refers to a repository"

Docker Hub
,

I have downloaded an image and modified it for my own front-end build requirements. Now I’d like to push it to the hub.

I have tried to run:

docker login
docker push marknorgate/apptitude-front-end-build

But this produces the following:

The push refers to a repository [docker.io/marknorgate/apptitude-front-end-build]
An image does not exist locally with the tag: marknorgate/apptitude-front-end-build

What am I doing wrong? I am using Docker v.1.12.1,

Sorted! Found a post - which I’m afraid I’ve lost - that fixed this.

For the sake of anyone reading later - was it that you needed to tag it before pushing? (Or can you share what you did?)

To be honest, I have just realised I totally misunderstood Docker. I’m just wading my way through the docs, so when I become more knowledgeable I shall come back and explain where I went wrong! That’s the best I can offer at the moment I"m afraid.

If anyone else gets here:
Be sure to build your code first with your username/repo before trying to push it.

Example:
docker build -t <username>/<repo>:<tag> .
Then you can push
docker push <username>/<repo>:<tag>

Hope this helps.

Thank you. jmmann. So that’s why.

For me, before “push” this works:

$ docker login -u your_username -p your_password

We are talking about your credentials for DockerHub
