Docker Maven Plugin Push to Dockerhub

[Ben Gill]

Hi,

I am having trouble getting push to work to my personal DockerHub registry.  I have tried a number of combinations, but none seem to work:

<registry>registry.hub.docker.com:443</registry>

<image>
    <alias>base-web</alias>
    <name>base-web</name>

    <!-- https://registry.hub.docker.com/repos/<my username> is resolvable -->
    <registry>registry.hub.docker.com:443</registry>

    <build>
        <assembly>
            <dockerFileDir>base-web</dockerFileDir>
        </assembly>
    </build>

</image>  

I have tried an auth setting using properties, <authConfig> and 

It is not clear to me what the relationship is between docker.io and dockerhub, or what the URL scheme is behind personal / org scoped Dockerhub repositories.

Is there an example anywhere?

Kind Regards

Do you mean your personal account on DockerHub (the public registry) ?
If so, then you dont need to configure any extra registry, since this is
the default.

Indeed you need to authenticate with your DockerHub account's
credentials. The recommended way is to do this in your
~/.m2/settings.xml as described in
http://fabric8io.github.io/docker-maven-plugin/authentication.html

For a first check -Ddocker.username=... -Ddocker.password=... on the
command line would do, too.

Your account needs to be configured as the user part of the image name.
So, in your example you want an image "base-web" and your account is
"ben" then you should use a <name>ben/base-web</name> in the configuration.

In general, the image name is "registry/user/image-name:tag", however
the registry part can be omitted when talking to DockerHub or when using
the <registry>private-registry</registry> part.

Yes my personal account on DockerHub.  Ok, I have removed the registry setting.

Ok, so all I need is ben/image-name, when I do that, I get this:

[INFO] DOCKER> ... The push refers to a repository [docker.io/bendg25/base-web]

[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.14.2:push (default-cli) on project docker: Unable to push 'bendg25/base-web': Repository does not exist: bendg25/base-web -> [Help 1]

You need to docker:build the image first so that it is available in your
Docker daemon (you must be able to see it with 'docker images'). The
push always goes from Docker daemon --> Docker registry (not directly).

Hi,

Thanks Roland, that has sorted it out.  So basically I have ommited the repository and just added <docker hub user id>/<my image name> and it works fine (using -Ddocker.username=foo -Ddocker.password=bar authentication properties).
