@gaocegege Do you want to assign a reviewer from Caicloud?

[gaocegege]

@jlewi

I think everyone could review it and most of us are on holiday now 😄

[jimexist]

related to the release cycle of this repo - i think we need to give our audience some expectation of release cycles, and to delete some code they have to be deprecated for at least two or three releases so that people don't get broken code.

[jimexist]

@gaocegege @jlewi i think you need to update the ref in https://coveralls.io/github/tensorflow/k8s, i.e. change the repo name.

[gaocegege]

SGTM, then it could be blocked until that time

[jlewi]

Tests should be fixed.
Please sync and rerun the tests.

dashboard/backend/handler/api_handler.go:143: job.Spec.TensorBoard undefined (type "github.com/kubeflow/tf-operator/pkg/apis/tensorflow/v1alpha1".TFJobSpec has no field or method TensorBoard)

I will fix it.

@gaocegege Is this PR still blocked?

No, I will update it soon.

examples/tf_job_tensorboard_azure.yaml, line 1 at r2 (raw file):

apiVersion: "kubeflow.org/v1alpha1"

We could probably just delete this file. I think the whole point of this file was to provide an example of TB on Azure. Now that we no longer support TB its not relevant.

pkg/apis/tensorflow/v1alpha1/types.go, line 55 at r2 (raw file):

	// TFImage defines the tensorflow docker image that should be used for default parameter server
	TFImage string `json:"tfImage,omitempty"`

Can we delete this now? Do we use this image for anything now? Maybe add a TODO.

I think we could add a TODO and set the issue to be good first issue, and maybe we could attract more contributors. If no one is interested and I could fix it in another PR. WDYT

I think we should add more contributor-friendly issues in the repo. Now we only have some regular contributors from several companies, it is not good, IMO

A TODO seems good to me. I'm also fine with just filing an issue for this and not blocking this PR.
