Add dockerhub repo

[klauspost]

Add to dockerhub.

It should be possible to set up so tags are automatically updated.

Docker repository vivino/rankdb has been created and connected with GitHub. New releases should automatically be built and published.

@zvymazal Should we release a new version to test it?

[zvymazal]

Yes 👍

[klauspost]

Will do. I have a dependency update as well.

[klauspost]

We might as well include #4 as well, but maybe with Go 1.13?

I had to add another GITHUB_TOKEN to travis, since releases are seen as branches and it was only available to master.

Anyway releases are working, but not so sure about dockerhub. Shouldn't there be something here: https://hub.docker.com/r/vivino/rankdb

[zvymazal]

There was some configuration missing. I'm testing it now.

The Docker image builds are breaking on these two:

COPY api/conf/conf.stub.toml /conf/conf.toml -> COPY conf/conf.stub.toml /conf/conf.toml
COPY deploy/docker-entrypoint.sh /usr/bin/ -> ?

[klauspost]

Still have the file. Lemme update.

🎉 https://hub.docker.com/r/vivino/rankdb/tags

[zvymazal]

The rules are configured to build master and release tags 🤞
