Ummm. Confused what example you're using.

It says: kedge create -f examples/guestbook/db.yaml

Yet our folder-name is guestbook-demo ?

Nvm, I am getting the same error too:

The old-example works (using the bitnami container). We'll have to trouble-shoot this and fix up the current container we use.

▶ ./kedge apply -f backend.yaml -f frontend.yaml -f db.yaml

hmm, that is strange it works on OpenShift but not on Kubernetes (minishift/minikube). We should report it so it can be fixed. Those CentOS images are in really bad shape.

[cdrage]

Hey @kadel I was toying the idea of changing our Guestbook-go example to reflect the official one (using redis + redis clusters, go application rather than PHP, etc.). Have you already begun work on this, and if not, mind if I take up this issue?

[cdrage]

Nevermind, I see @surajnarwade has already began that. What's the status of your work @surajnarwade ? I could provide some help.

[surajnarwade]

@cdrage @kadel @containscafeine , I have started working on it.
so @cdrage , I am following this official example https://kubernetes.io/docs/tutorials/stateless-application/guestbook/

[cdrage]

Okay! Push to a fork or GitHub PR if you need help. I started on it for a bit before I realized that you had already began.
