3-9: LGTM: Section block is well-structuredThe section block effectively communicates the pipeline failure and uses markdown formatting for emphasis. The dynamic environment variable is correctly implemented.
Consider adding more context to the message, such as the branch name or commit SHA, to help identify the specific pipeline run. For example:
- "text": "*:rotating_light: Pipeline failing for *${{ env.ENVIRONMENT }}* :rotating_light:*\n\nPlease check the workflow for more details." + "text": "*:rotating_light: Pipeline failing for *${{ env.ENVIRONMENT }}* :rotating_light:*\n\nBranch: `${{ github.ref_name }}`\nCommit: `${{ github.sha }}`\n\nPlease check the workflow for more details."
11-23: LGTM: Actions block provides useful quick accessThe actions block is well-structured and includes a button that links directly to the GitHub Actions run, which is very helpful for quick troubleshooting.
Consider enhancing the button's visibility and clarity:
{ "type": "button", "text": { "type": "plain_text", - "text": "View Run" + "text": "View Run :arrow_right:", + "emoji": true }, + "style": "primary", "url": "https://github.com/${{ github.repository }}/actions/runs/${{ github.run_id }}" }This change adds an arrow emoji to the button text, enables emoji rendering, and sets the button style to "primary" for better visibility.

153-169: LGTM with suggestions for improvementThe implementation of the
send-slack-messagejob is well-structured and serves its purpose of notifying about pipeline failures. Here are some suggestions to enhance its robustness and flexibility:
Consider adding error handling and logging for the Slack message sending step. This will help diagnose issues if the notification fails to send.
The payload file path is currently hardcoded. For better flexibility, consider parameterizing this path, especially if you plan to use multiple templates in the future.
Here's a suggested improvement for error handling and logging:
- name: Send GitHub slack message id: slack env: SLACK_BOT_TOKEN: ${{ secrets.SLACK_BOT_TOKEN }} ENVIRONMENT: test uses: slackapi/[email protected] with: channel-id: ${{ secrets.SLACK_CHANNEL_ID_FOR_RELEASES }} payload-file-path: "./.github/slack-templates/pipeline-failed.json" - name: Check Slack message status if: failure() run: | echo "Failed to send Slack message" echo "Slack API Response: ${{ steps.slack.outputs.slack-result }}"For parameterizing the payload file path:
env: SLACK_PAYLOAD_PATH: "./.github/slack-templates/pipeline-failed.json" ... with: payload-file-path: ${{ env.SLACK_PAYLOAD_PATH }}This allows you to easily change the payload file path for different scenarios if needed in the future.
155-155: Consider more granular failure notificationsThe current setup notifies on any workflow failure, which is good for overall monitoring. However, you might want to consider more granular notifications for specific job failures. This could help in quickly identifying which part of the pipeline failed without needing to check the GitHub Actions interface.
You could achieve this by:
- Creating separate Slack message templates for different types of failures.
- Using job outputs to pass failure information to the
send-slack-messagejob.- Conditionally selecting the appropriate template based on which job(s) failed.
This approach would require restructuring the
send-slack-messagejob and creating additional templates, but it could significantly improve the speed of identifying and responding to specific types of failures..github/workflows/ci-cd-prod.yml (1)
138-154: LGTM! Consider adding a comment for clarity.The implementation of the
send-slack-messagejob looks good. It's correctly set up to trigger on failure of the deployment jobs and uses the Slack GitHub action to send notifications.Consider adding a brief comment above the job to explain its purpose, for example:
# Notify team via Slack if any deployment job fails send-slack-message: name: Send Slack message on failure ...This would enhance readability and make the workflow's structure more immediately clear to other developers.

.github/slack-templates/pipeline-failed.json (3)
1-25: LGTM: Overall structure is correctThe JSON structure follows the Slack Block Kit format, which is appropriate for creating custom Slack messages. The use of a "blocks" array allows for a flexible and well-structured message layout.
10-10: LGTM: Divider block is correctly implementedThe divider block provides a clear visual separation between the message content and the action button.
1-25: Overall: Well-structured Slack message template for pipeline failuresThis JSON file effectively defines a Slack message template for alerting about pipeline failures. It uses Slack's Block Kit format correctly and includes all necessary components: a clear message, visual separation, and an action button for quick access to the failing run.
The use of GitHub Actions context variables ensures that the message will be dynamically populated with relevant information. The suggested enhancements, if implemented, would further improve the clarity and usability of the message.
Great job on implementing this alerting mechanism!
.github/workflows/ci-cd-staging.yml (3)
117-133: Summary: Changes align well with PR objectives.The addition of the
send-slack-messagejob successfully implements an alerting mechanism for failing pipelines, which aligns perfectly with the PR objectives. The job is well-integrated into the existing workflow and follows good practices for GitHub Actions:
- It runs only on workflow failure, ensuring notifications are sent when needed.
- It uses secrets for sensitive information, maintaining security.
- It depends on the relevant jobs in the workflow, ensuring it runs after all critical steps.
With the minor suggestions for improvement addressed (updating the Slack GitHub Action version and verifying the template file), this implementation will provide valuable notifications for pipeline failures in the staging environment.
119-119: Verify the existence of all dependent jobs.The
send-slack-messagejob depends on several other jobs. Let's ensure all these jobs exist in the workflow:#!/bin/bash # Verify the existence of all dependent jobs dependent_jobs=("deploy-infra-staging" "deploy-apps-staging" "deploy-slack-notifier-staging" "run-e2e-tests" "publish-schema-npm") missing_jobs=() for job in "${dependent_jobs[@]}"; do if ! grep -q "name: $job" .github/workflows/ci-cd-staging.yml; then missing_jobs+=("$job") fi done if [ ${#missing_jobs[@]} -eq 0 ]; then echo "All dependent jobs exist in the workflow." else echo "Error: The following dependent jobs are missing from the workflow:" printf '%s\n' "${missing_jobs[@]}" exit 1 fi
117-133: LGTM: Well-implemented Slack notification for pipeline failures.The new
send-slack-messagejob is well-structured and correctly integrated into the workflow. It's set to run on failure, which aligns with the PR objective of alerting on failing pipelines.Consider updating the Slack GitHub Action to the latest version.
The current implementation uses
slackapi/[email protected]. Consider updating to the latest version (v1.28.0 as of this review) to ensure you have the most recent features and bug fixes.You can update the action version like this:
- uses: slackapi/[email protected] + uses: slackapi/[email protected]Verify the existence of the Slack message template file.
The job references a Slack message template file at
./.github/slack-templates/pipeline-failed.json. Ensure this file exists in your repository and contains the appropriate message structure.✅ Verification successful
