Learning Approach

This is a REFERENCE guide!

Use on-the-job: Build real integrations for Platform
Hands-on first: Try features in a test workspace
Just-in-time: Read sections when you need them

Quick Start

Immediate Actions (Day 1):

Create a Slack App:

# Go to: https://api.slack.com/apps
# Create New App → From scratch
# Name: "Platform Bot" (or similar)
# Pick your workspace

Enable Incoming Webhooks:

# In your app settings:
Features → Incoming Webhooks → Activate
# Add New Webhook to Workspace
# Select a test channel

Test your first webhook:

curl -X POST -H 'Content-type: application/json' \
--data '{"text":"Hello from Platform!"}' \
YOUR_WEBHOOK_URL

Key Skills to Master

Week 1:

Send formatted messages with Webhooks
Use Block Kit for rich layouts
Route messages to correct channels
Create simple slash commands

Week 2:

Build a Slack bot with Python Bolt
Handle button clicks & modal interactions
Subscribe to events (mentions, reactions)
Thread messages for context

Week 3:

Aggregate alerts to reduce noise
Implement severity-based routing
Integrate with Tekton pipelines
Build incident management workflow

Tips for Platform Integration

Start with Webhooks:
Simple CI/CD notifications
Pipeline success/failure alerts
Don't over-engineer early
Reduce Noise from Day 1:
Use threads for related updates
Aggregate similar alerts
Different channels by severity
Make Alerts Actionable:
Add "View Logs" button
Link to dashboards
Include relevant context (commit SHA, PR link)
Security:
Never commit webhook URLs to git
Use environment variables
Rotate tokens regularly

Common Use Cases

Use Case 1: Pipeline Failure Alert

Pipeline Failed: build-service

Pipeline: platform-build-123
Commit: abc123 (fix: update deps)
Author: demo_user
Duration: 5m 32s

[View Logs] [Rerun Pipeline] [View PR]

Use Case 2: Incident Notification

CRITICAL: High Error Rate Detected

Service: tekton-controller
Error Rate: 15% (threshold: 5%)
Time: 2026-03-03 14:23 UTC

[View Dashboard] [Create Incident] [Acknowledge]

Use Case 3: Daily Digest

Platform Daily Summary - 2026-03-03

Successful: 142 pipelines
Failed: 8 pipelines
Avg Duration: 3m 45s
Top Failure: image-build (5 failures)
