You can use your docker images hosted on https://hub.docker.com/.

Overview

You can use your public images without the need to set any configuration. In order to push private docker images to docker hub, you need to set access credentials.

Create a secret containing the credentials to use with docker hub

{
    "auths": {
        "https://index.docker.io/v1/": {
            "auth": "YW11cmRhY2Esdfdsflkdjsf==",
            "email": "[email protected]"
        }
    }
}

or

{
    "auths": {
        "https://index.docker.io/v1/": {
            "auth": "YW11cmRhY2Esdfdsflkdjsf=="
        }
    }
}

N.B. that the auth must contain a concatenation of the username, a colon, and the password, i.e. user:password, you can find the auths in your $HOME/.docker/config.json for instance, or you can create this auth using a simple python script:

import base64
base64.b64encode("user:secret".encode())
kubectl create secret generic docker-conf --from-file=config.json=./config.json -n polyaxon

Add the secret to the connections catalog

If you are using Kaniko

  - name: docker-connection
    kind: registry
    schema:
      url: destination
    secret:
      name: docker-conf
      mountPath: /kaniko/.docker

If you are using dockerizer using the default root user:

  - name: docker-connection-dockerizer
    kind: registry
    schema:
      url: destination
    secret:
      name: docker-conf
      mountPath: /root/.docker
