I checked the log of Kube-slack and I noticed this error in both K8s clusters that I run in Azure.

Cluster 1

My configuration: K8s 1.12.7 deployed with Kubespray Kube-Slack v4.2.0 deployed with helm

The pods are not restarted and work fine but this is still an issue.

@whs could you please take a look?

@pierluigilenoci helm install stable/kube-slack --set envVars.SLACK_URL="URL" --set envVars.SLACK_USERNAME="USERNAME" --set envVars.SLACK_CHANNEL="CHANNEL" --name kube-slack

The SLACK_USERNAME and SLACK_CHANNEL seem to also be required
