TODO: This section needs to be updated

Tensorboard is deployed just before training starts. To connect:
Configure TensorBoard to point to your model location

```
PODNAME=$(kubectl get pod -l app=tensorboard-${JOB_NAME} -o jsonpath='{.items[0].metadata.name}')
kubectl port-forward ${PODNAME} 6006:6006
ks param set tensorboard --env=${KSENV} logDir ${LOGDIR}

```

Assuming you followed the directions above if you used GCS you can use the following value

```
LOGDIR=gs://${BUCKET}/${MODEL_PATH}
```

Then you can deploy tensorboard

```
ks apply ${KSENV} -c tensorboard
```

To access tensorboard using port-forwarding

```
kubectl -n jlewi port-forward service/tensorboard-tb 8090:80
```
Tensorboard can now be accessed at [http://127.0.0.1:8090](http://127.0.0.1:8090).
