Create Slack channel for Incident Management

Overview

Streamline incident response with this self-service action. It automatically creates dedicated Slack channels for your services, optionally adding key team members during setup.

Key Benefits

• Faster Incident Response: Instantly create communication channels when issues arise.
• Consistent Process: Ensure standard channel naming and member inclusion.
• Developer Self-Service: Empower teams to create incident channels without needing extra Slack permissions.
• Reduced Manual Steps: Automate a routine task, freeing up time for your team.

Prerequisites

1. Port's GitHub app needs to be installed.

2. Setup Slack App:

   1. Create a slack app and install it on a workspace.
   2. Add the following permissions to the slack app:
      • Create channel (Required) : channels:manage groups:write im:write mpim:write
      • Find a user with an email address (Optional) : users:read.email
      • Invite users to channel (Optional) : channels:write.invites groups:write.invites mpim:write.invites
   warning

   Without scopes for Find a user with an email address and Invite users to channel, the channel will be created but users will not be added to it.

   3. Then install the app in your slack workspace.
   4. Navigate back to the OAuth & Permissions page. You'll see an access token under OAuth Tokens for Your Workspace that you will use in the BOT_USER_OAUTH_TOKEN GitHub secret.
   
   

3. In your GitHub repository, go to Settings > Secrets and add the following secrets:

   • BOT_USER_OAUTH_TOKEN - Slack Bot User Oauth Token generated for the slack app.
   • PORT_CLIENT_ID - Your port client id.
   • PORT_CLIENT_SECRET - Your port client secret.

4. Create a service blueprint with the following JSON definition:
