Push the docker image to dockerhub at each autokeras release

[gabrieldemarmiesse]

We now have a working docker image, we should:

• push it to dockerhub at each release with github action

• Maybe give instructions on how to use it? I'm not sure. People use docker images in all kinds of way, Usually, if they go for the docker image instead of a pip install, it means they already know how to use docker well.

We will use the README file in the docker folder as the documentation. Would you help us update the autogen.py to use it?

For DockerHub, I can add the secrets to the repo and let's use this action to do it:
https://github.com/marketplace/actions/publish-docker
The docker will be uploaded to https://hub.docker.com/repository/docker/haifengjin/autokeras
I can add you as a collaborator on DockerHub.
Let me know your DockerHub ID.

Thanks.

My dockerhub username is gabrieldemarmiesse

Do you tyink it would make sense for us to have a repository on dockerhub for keras projects?

[haifeng-jin]

@gabrieldemarmiesse I have added you as a collaborator.
I think you mean an organization on DockerHub with repositories for different Keras projects.
That would be great.
We can use my account before this organization is created.
And move to it whenever it is ready.

@fchollet Do we have a Keras organization or something similar on DockerHub? Thanks.
