Kured

This repository uses Kured to ensure the cluster nodes are properly rebooted during a scheduled OS upgrade reboot event.

Slack

Slack notifications can be enabled, allowing the end-user to receive notifications when each cluster node is rebooted.

Slack Application

Create a new application from scratch, named Kured, and assign it to the intended workspace where Kured notifications will be received.

Webhook

Activate incoming webhooks and create a new webhook, specifying in what channel Kured will have permissions to post cluster updates. The webhook will have the following format:


https://hooks.slack.com/services/<token>/<token>/<token>

Notify URL

Encrypt the global_map.credentials.kured.slack.notify.url value with ansible-vault and insert it into the all.yaml group variables file. Notify URL decrypted format:


global_map:
  credentials:
    kured:
      slack:
        notify:
          url: slack://<token>/<token>/<token>
