Did you need to run dep ensure to see if Gopkg.lock needs updating?

We should look into possibly improving the CLI to leverage this in the future.

I don't know if you need to run dep ensure. Maybe run it anyway.

Note to self on testing:

It takes up to 20s for a new pod to come up locally. So the 3s retry is not long enought to outlast this. Modify the timeout to be >20s (e.g. 30s).

Then, delete the repo-server:

kubectl delete $(kubectl get pods -o name|grep repo-server) && watch kubectl get pods

And hard refresh an app.
