Slack Deploy Pipeline Notifications

Post GitHub Action deploy workflow progress notifications to Slack.

Features

• Posts summary message at beginning of the deploy workflow, surfacing commit message and author
• Maps GitHub commit author to Slack user by full name, mentioning them in the summary message
• Threads intermediate stage completions, sending unexpected failures back to the channel
• Updates summary message duration at conclusion of the workflow
• Supports pull_request, push, release, schedule, and workflow_dispatch event types

Setup

1. Create a Slack App for your workspace
2. Under OAuth & Permissions, add two Bot Token Scopes:
   1. chat:write to post messages
   2. chat:write.customize to customize messages with GitHub commit author
   3. users:read to map GitHub user to Slack user
3. Install the app to your workspace
4. Copy the app's Bot User OAuth Token from the OAuth & Permissions page
5. Create a GitHub secret with this token, named SLACK_DEPLOY_BOT_TOKEN
6. Invite the bot user into the Slack channel you will post messages to (/invite @bot_user_name)
7. Click the Slack channel name in the header, and copy its Channel ID from the bottom of the dialog
