# Project Status Meeting 4

> This article discusses the fourth project status meeting focusing on CI/CD workflows for Node.js, Java, and Python applications using GitHub Actions and Kubernetes.

Welcome to the fourth project status meeting for Dasher Technologies. In this session, we’ll review our progress on GitHub Actions workflows and plan out a reusable deployment strategy across Node.js, Java, and Python applications.

## Agenda

* Recap: Node.js CI/CD with GitHub Actions
* Expansion plan for Java and Python services
* Designing a reusable Kubernetes deployment workflow
* Action items and next steps

## Recap: Node.js CI/CD Implementation

In our previous meeting, Alice’s team successfully implemented a CI/CD pipeline for their Node.js application using GitHub Actions. The workflow performs the following steps:

1. Check out the repository
2. Install dependencies
3. Run unit tests
4. Build and push the Docker image
5. Deploy to Kubernetes

```yaml theme={null}
# .github/workflows/nodejs-ci.yml
name: Node.js CI/CD

on:
  push:
    branches: [ main ]

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2

      - name: Set up Node.js
        uses: actions/setup-node@v2
        with:
          node-version: '14'

      - run: npm install
      - run: npm test

      - name: Build and push image
        uses: docker/build-push-action@v2
        with:
          context: .
          push: true
          tags: ${{ secrets.DOCKER_HUB }}/app-node:latest

      - name: Deploy to Kubernetes
        uses: azure/k8s-deploy@v1
        with:
          manifests: k8s/deployment.yml
```

## Expansion to Java and Python Applications

Dasher Technologies will now extend this CI/CD pattern to its Java and Python services. Because all three microservices share the same Kubernetes deployment model, we’ll extract common steps into a single reusable workflow.

| Service   | Language | CI/CD Workflow File |
| --------- | -------- | ------------------- |
| Service A | Node.js  | `nodejs-ci.yml`     |
| Service B | Java     | `java-ci.yml`       |
| Service C | Python   | `python-ci.yml`     |

  Extracting shared deployment steps into a reusable workflow ensures consistency, reduces duplication, and makes future updates easier.
</Callout>

## Designing the Reusable Deployment Workflow

We’ll create a reusable workflow at `.github/workflows/deploy.yml` containing the standardized Kubernetes deployment logic:

```yaml theme={null}
# .github/workflows/deploy.yml
name: Reusable Kubernetes Deployment

on:
  workflow_call:

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2

      - name: Set up kubectl
        uses: azure/setup-kubectl@v1

      - name: Authenticate to Kubernetes
        run: |
          kubectl config set-context ${{ secrets.K8S_CONTEXT }}

      - name: Apply manifests and rollout
        run: |
          kubectl apply -f k8s/deployment.yml
          kubectl rollout status deployment/${{ github.job }}
```

Each service-specific workflow will call this reusable deployment:

```yaml theme={null}
# .github/workflows/nodejs-ci.yml (excerpt)
...
jobs:
  build:
    # build steps here

  deploy:
    uses: ./.github/workflows/deploy.yml
    with:
      # pass any required inputs or secrets
```

## Action Items

* Finalize and review `deploy.yml` template
* Update Java and Python workflows to invoke the reusable deployment
* Run end-to-end tests for all three services
* Document the new CI/CD pattern for the engineering team
