💬 Slack

Use the interactive kwatch manager to configure Slack alerts. It stores credentials in Kubernetes Secrets and verifies the installation. The configuration fragments below explain provider settings; they are not separate installation steps.

If you want to enable Slack, provide either a webhook URL or a bot token with channel.

Webhook mode:

Parameter	Description	Required
alert.slack.webhook	Slack webhook URL	Yes
alert.slack.channel	📢 Override channel	No
alert.slack.title	✏️ Custom title	No
alert.slack.text	✏️ Custom text	No
alert.slack.compact	📏 Single-line mode	No

Bot Token mode:

Parameter	Description	Required
alert.slack.token	Slack bot token (xoxb-...)	Yes
alert.slack.channel	📢 Channel to post to	Yes
alert.slack.title	✏️ Custom title	No
alert.slack.text	✏️ Custom text	No
alert.slack.compact	📏 Single-line mode	No

💡 Pro tip: When using bot token mode, alerts become threaded conversations — root message on first alert, updates as replies. Clean and organized! 🧹

Compact mode

  slack:
    webhook: "${file:/config/slack-webhook}"
    compact: true
