Add Comprehensive Slack Notification Support for All MAS Pipelines

🎯 Overview

This PR adds complete Slack notification support for all MAS DevOps pipelines, enabling real-time notifications for pipeline execution status. This is a brand new feature that provides:

• ✅ Install Pipeline - Notifications for MAS instance installation
• ✅ Upgrade Pipeline - Notifications for MAS instance upgrades
• ✅ Update Pipeline - Notifications for cluster-wide catalog updates
• ✅ Uninstall Pipeline - Notifications for MAS instance removal

CLI PR: ibm-mas/cli#2195
TDD: https://github.ibm.com/maximoappsuite/tdd/blob/master/docs/2025/6640-cli-slack-integration.md

Users can now receive Slack notifications at every stage of pipeline execution, including pipeline start, Ansible task progress, and pipeline completion with success/failure status.

🔄 Flow of Changes

High-Level Flow (All Pipelines)

User runs any MAS pipeline command with Slack credentials
    ↓
CLI validates and prepares namespace
    ↓
Secret creation function is called (prepareInstallSecrets or prepareUpdateSlackSecrets)
    ↓
Checks if target namespace exists (mas-{instanceId}-pipelines or mas-pipelines)
    ↓
Creates `mas-devops-slack` secret with SLACK_TOKEN and SLACK_CHANNEL
    ↓
Pipeline runs with Slack notifications enabled
    ↓
Notifications sent to Slack at each pipeline stage:
    • Pipeline Start - Creates thread
    • Ansible Task Start - Posts task start message
    • Ansible Task Complete - Updates with success/failure
    • Pipeline Complete - Posts final status and cleans up

Example Commands

Install Pipeline:

mas install --instance-id dev1 --slack-token xoxb-xxx --slack-channel "#mas-notifications"

Upgrade Pipeline:

mas upgrade --instance-id dev1 --slack-token xoxb-xxx --slack-channel "#mas-notifications"

Update Pipeline:

mas update --slack-token xoxb-xxx --slack-channel "#mas-notifications"

Uninstall Pipeline:

mas uninstall --instance-id dev1 --slack-token xoxb-xxx --slack-channel "#mas-notifications"

Detailed Notification Flow

1. Pipeline Start: Creates Slack thread in mas-pipelines namespace
2. Ansible Task Start: Posts task start message to thread
3. Ansible Task Complete: Updates task message with success/failure status
4. Pipeline Complete: Posts final status and cleans up ConfigMap

📋 Behavior in Different Conditions

Condition 1: Instance-Specific Pipelines (Install/Upgrade/Uninstall)

When: Pipeline has an instance ID (e.g., mas install --instance-id dev1)

Behavior:

• Namespace: mas-{instanceId}-pipelines (e.g., mas-dev1-pipelines)
• Secret: mas-devops-slack created in instance namespace
• ConfigMap: slack-thread-{instanceId}-{pipelineName} (e.g., slack-thread-dev1-Install)
• Secret contains: MAS_INSTANCE_ID, SLACK_TOKEN, SLACK_CHANNEL

Example:

mas install --instance-id dev1 --slack-token xoxb-xxx --slack-channel "#mas-notifications"

Condition 2: Update Pipeline (Cluster-Wide)

When: Pipeline has NO instance ID (e.g., mas update)

Behavior:

• Namespace: mas-pipelines (cluster-wide namespace)
• Secret: mas-devops-slack created in cluster namespace
• ConfigMap: slack-thread-update-{pipelineName} (e.g., slack-thread-update-Update)
• Secret contains: SLACK_TOKEN, SLACK_CHANNEL (no instance ID)

Example:

mas update --slack-token xoxb-xxx --slack-channel "#mas-notifications"

Condition 3: No Slack Credentials Provided

When: User doesn't provide --slack-token or --slack-channel

Behavior:

• No secret created
• Pipeline runs without Slack notifications
• No errors or warnings

Condition 4: Empty Channel List

When: Notification function called with empty channels list

Behavior:

• Function exits early with informative message
• Returns appropriate value (None or False)
• No Kubernetes or Slack API calls made

Condition 5: Namespace Doesn't Exist

When: Target namespace (mas-pipelines or mas-{instanceId}-pipelines) doesn't exist

Behavior:

• Secret creation skipped
• Warning logged
• Pipeline continues without Slack notifications

📝 Changes Made

Common Changes

Core Functionality:

• ✅ Extended Slack notification system to support pipelines without instance IDs
• ✅ Added namespace existence validation before secret creation
• ✅ Added empty channel list validation for all notification functions
• ✅ Unified ConfigMap naming convention for both pipeline types

Error Handling:

• ✅ Graceful handling of missing namespaces
• ✅ Early exit for empty channel lists
• ✅ Proper return types for all error conditions

Modified Files

1. src/mas/devops/tekton.py

Changes:

• Added new function prepareUpdateSlackSecrets() (lines 618-680)
  • Validates mas-pipelines namespace exists
  • Creates mas-devops-slack secret with SLACK_TOKEN and SLACK_CHANNEL
  • Only creates secret when both token and channel are provided
  • Includes comprehensive error handling and logging

Key Code:

def prepareUpdateSlackSecrets(dynClient: DynamicClient, slack_token: str = None, slack_channel: str = None) -> None:
    """Create or update Slack secret for MAS Update pipeline (cluster-wide)."""
    namespace = "mas-pipelines"
    
    # Check if namespace exists
    namespaceAPI = dynClient.resources.get(api_version="v1", kind="Namespace")
    try:
        namespaceAPI.get(name=namespace)
    except NotFoundError:
        logger.warning(f"Namespace {namespace} does not exist. Skipping Slack secret creation.")
        return
    
    # Only create secret if both token and channel provided
    if not slack_token or not slack_channel:
        logger.info("Slack token or channel not provided. Skipping Slack secret creation.")
        return
    
    # Create secret...

2. /Users/anilprajapati/ibm/mas/cli/python/src/mas/cli/update/app.py

Changes:

• Added import for prepareUpdateSlackSecrets (line 26)
• Added call to create Slack secret after namespace preparation (lines 207-215)
• Includes user feedback with Halo spinner

Key Code:

from mas.devops.tekton import prepareUpdateSlackSecrets

# After namespace preparation
if slack_token and slack_channel:
    with Halo(text='Preparing Slack notification secrets', spinner='dots') as spinner:
        prepareUpdateSlackSecrets(dynClient, slack_token, slack_channel)
        spinner.succeed('Slack notification secrets prepared')

3. bin/mas-devops-notify-slack

Changes:

• Updated notifyPipelineStart() (lines 100-157)

  • Added empty channel list validation (lines 101-104)
  • Added support for None/empty instance ID (lines 105-108)
  • Uses mas-pipelines namespace for update pipeline

• Updated notifyAnsibleStart() (lines 160-217)

  • Added empty channel list validation (lines 161-164)
  • Added support for None/empty instance ID (lines 166-169)

• Updated notifyAnsibleComplete() (lines 219-306)

  • Added empty channel list validation (lines 220-223)
  • Added support for None/empty instance ID (lines 225-228)

• Updated notifyPipelineComplete() (lines 309-387)

  • Added empty channel list validation (lines 310-313)
  • Added support for None/empty instance ID (lines 315-318)

Key Pattern:

# Exit early if no channels provided
if not channels or len(channels) == 0:
    print("No Slack channels provided - skipping notification")
    return None  # or False for bool functions

# Handle update pipeline (no instance ID)
if instanceId is None or instanceId == "":
    namespace = "mas-pipelines"
else:
    namespace = f"mas-{instanceId}-pipelines"

4. src/mas/devops/slack.py

Changes:

• Updated createThreadConfigMap() (lines 274-303)

  • Uses "update" as identifier when instanceId is None/empty

• Updated getThreadConfigMap() (lines 306-337)

Key Pattern:

# Use "update" as identifier for update pipeline
instance_identifier = instanceId if instanceId else "update"
configmap_name = f"slack-thread-{instance_identifier}-{pipelineRunName}"

🔍 Key Technical Details

ConfigMap Naming Convention

• Instance-specific: slack-thread-{instanceId}-{pipelineName}
  • Example: slack-thread-dev1-Install
• Update pipeline: slack-thread-update-{pipelineName}
  • Example: slack-thread-update-Update

Namespace Selection Logic

if instanceId is None or instanceId == "":
    namespace = "mas-pipelines"  # Cluster-wide
else:
    namespace = f"mas-{instanceId}-pipelines"  # Instance-specific

Secret Structure

Instance-Specific Pipeline:

apiVersion: v1
kind: Secret
metadata:
  name: mas-devops-slack
  namespace: mas-{instanceId}-pipelines
type: Opaque
data:
  MAS_INSTANCE_ID: <base64-encoded-instance-id>
  SLACK_TOKEN: <base64-encoded-token>
  SLACK_CHANNEL: <base64-encoded-channel>

Update Pipeline:

apiVersion: v1
kind: Secret
metadata:
  name: mas-devops-slack
  namespace: mas-pipelines
type: Opaque
data:
  SLACK_TOKEN: <base64-encoded-token>
  SLACK_CHANNEL: <base64-encoded-channel>
