    Set Up n8n Automation Workflows for CI/CD Integration


    Overview

    n8n automates deployment pipelines by integrating with GitHub, triggers builds in Jenkins, and deploys Docker containers when new code is pushed.

    Prerequisites

    • n8n installed.

    • GitHub repository with webhook support.

    • Jenkins server with API token.

    • Docker Hub account and credentials.

    Workflow Setup

    1. Prepare n8n Environment

    • Navigate to http://localhost:5678 and log in.
    • Click “Workflows,” then “+ New” and name it (e.g., “CI/CD Pipeline”).
    • Click “+” to add nodes.

    2. Trigger Node: GitHub Webhook

    Node: Webhook

    Settings:

    • Path: github-push
    • GitHub Webhook: https://<n8n-host>/webhook/github-push for push events

    Output: Push event data (e.g., {{ $json.repository.full_name }}).

    3. Build Node: Jenkins

    Node: Jenkins

    Settings:

    • Credentials: Jenkins API token
    • Job Name: build-job
    • Parameters: Commit SHA {{ $node["Webhook"].json.after }}

    Output: Build triggered.

    4. Deploy Node: Docker

    Node: Docker

    Settings:

    • Credentials: Docker Hub credentials
    • Operation: Run
    • Image: my-app:latest

    Output: Container deployed.

    Workflow Summary

    • Flow: Webhook (GitHub) → Jenkins (build) → Docker (deploy).

    • Execution: ~2 minutes.

    Benefits

    • Speeds up delivery cycles by ~70%.

    • Reduces deployment errors with automation.

    • Ensures repeatable CI/CD processes.

    Troubleshooting

    • Webhook Fail: Verify GitHub webhook URL.

    • Jenkins Issues: Check API token and job name.
