The GitHub action for Kubeflow triage is currently using the image hamelsmu/kubeflow-triage

https://github.com/kubeflow/code-intelligence/blob/9fceba0c7141ab8e02b0f049ee696194cdf24eb4/.github/workflows/build_image.yaml#L15

https://github.com/kubeflow/code-intelligence/blob/9fceba0c7141ab8e02b0f049ee696194cdf24eb4/Issue_Triage/action/action.yml#L20

We should instead push the image to Docker in the kubeflow organization and then update the image to use that.

Note GitHub actions doesn't currently support GCR.

We have the kubeflow github organization https://hub.docker.com/orgs/kubeflow

We have the kubeflowrobot account for automating pushes to kubeflow

I created a personal access token for this account. This is currently stored in google's internal secret management system; Google team can access it.

I replaced the DOCKER_USERNAME and DOCKER_PASSWORD secrets on kubeflow/code-intelligence with kubeflowrobot and the associated access token.

When the action triggered we got a permission error trying to push to DockerHub https://github.com/kubeflow/code-intelligence/commit/ea1e5995d7e9bc8e6326c1adf9c5149af2294ced/checks?check_suite_id=329459221

I'm going to try reproducing it locally; by logging in as the kubeflow robot to docker and building the image.

I got the same error.

It looks like I had to do a couple things

1. In Docker hub I had to create the repository kubeflow/kubeflow-triage
2. I had to add the developer team with read/write permissions on that repository

I was then able to successfully run docker push using the kubeflowrobot account
