Deployment notifications

Create deployment notifications. Spike?

A deployment to test / preprod / prod should trigger a notification to a channel. The notification should contain all relevant commit messages, clearly state which environment is being referenced, and clearly show the success / fail state of the deployment.

The comms method - which Slack or MS Teams channel - could vary depending on environment, so plan for this. For example:

• Notify catalogue team on deploy to dev & test
  • Test, because we want to know it's working. Dev notification as a sort of "FYI, hey, I'm using dev for {something}"
• Notify a "preview stakeholders" group of upgrades to preprod
  • Bonus points for conditional notification - successful deploys to stakeholders, failed deploys to catalogue team only?
• Notify an "all users" group of successful upgrades to prod
  • Bonus points for conditional notification - successful deploys to stakeholders, failed deploys to catalogue team only?

Initially just Slack for now until / if we get a Teams channel to notify DIP team. But if there's spare time and someone wants to try creating Teams notifications, I've added some notes in a comment below

What notifications we want

Test

• Once a new deployment has passed tests
• If a new deployment fails automated tests / any other part of the workflow

Pre prod

• Deployment completed

Prod

• Deployment completed

If anyone has spare time and wants to try setting up Teams notifications, I've created a Catalogue Notifications channel and added an incoming webook. This is stored in 1Password and also an environment secret for preprod in the f-m-d repo.

Jeremy, Sean and Yvan are team owners so can help with access.

Example GHA step:

preprod-release-notify:
    name: Send staging release message to Teams
    runs-on: ubuntu-latest
    needs: build-deploy-preprod
    steps:
      - name: Microsoft Teams Notification
        uses: skitionek/notify-microsoft-teams@master
        if: always()
        with:
          webhook_url: ${{ secrets.MICROSOFT_TEAMS_WEBHOOK_URI }}
          needs: ${{ toJson(needs) }}
          job: ${{ toJson(job) }}
          overwrite: "{title: `Deployed a new release to preproduction`}"
