GuestBook demo Admin GUI refuses connection


#1

Hi,

We’ve been testing Replicated over the past couple of weeks. Last week we were able to run the Kubernetes GuestBook application and deploy releases over the unstable channel, but this week the Replicated UI becomes unresponsive.

The connection seems to get blocked. “Error while checking for updates: Error: Request has been terminated Possible causes: the network is offline, Origin is not allowed by Access-Conrol-Allow-Origin, the page is being unloaded.”

We are running this on an AWS ubuntu instance as the demo describes. Any insights on what could be wrong or has changed.

Thanks.

You can check that all replicated and retraced pods are running using kubectl get pods

Also there will usually be relevant errors in the replicated container logs kubectl logs <replicated pod name> replicated

Thank you. From that I was able to determine that your GuestBook application is now unable to run on an AWS with the default storage of 8GB. I had to increase the storage of the instance and am now able to run. Here was the clue.

cron pod had an entry in the events saying that it was terminated because “The node was low on resource: imagefs”.

You might want to include the required disk size in your server specifications for the Guestbook guide if the default size is no longer sufficient.

Thanks for the assistance.
