CI/CD Deployment

The current implementation of the OpenTelemetry .NET project does not have CI/CD configured. Below are the next steps recommended for setting up a CI/CD pipeline to facilitate automated deployments.

Steps to Set Up CI/CD

1. Select a CI/CD Tool: Choose a service that supports building and deploying .NET applications. Popular options include GitHub Actions, Azure DevOps, CircleCI, Travis CI, and Jenkins.

2. Create CI/CD Configuration File: Depending on the selected tool, create a configuration file in the repository.

   • For GitHub Actions: Create a .github/workflows/ci.yml file with the following content:

     name: CI
     
     on:
       push:
         branches:
           - main
       pull_request:
         branches:
           - main
     
     jobs:
       build:
         runs-on: ubuntu-latest
     
         steps:
           - name: Check out code
             uses: actions/checkout@v2
     
           - name: Set up .NET
             uses: actions/setup-dotnet@v1
             with:
               dotnet-version: '8.0.x'
     
           - name: Restore dependencies
             run: dotnet restore ./examples/MicroserviceExample/WorkerService
     
           - name: Build
             run: dotnet build ./examples/MicroserviceExample/WorkerService --configuration Release
     
           - name: Publish
             run: dotnet publish ./examples/MicroserviceExample/WorkerService --configuration Release --output ./out
     
           - name: Build Docker image
             run: docker build -t opentelemetry-example-workerservice -f ./examples/MicroserviceExample/WorkerService/Dockerfile .
     
           - name: Publish Docker image
             run: docker push opentelemetry-example-workerservice
     

   • For Azure DevOps: Create a azure-pipelines.yml file:

     trigger:
       - main
     
     pool:
       vmImage: 'ubuntu-latest'
     
     steps:
       - task: DotNetCoreCLI@2
         displayName: 'Restore'
         inputs:
           command: 'restore'
           projects: './examples/MicroserviceExample/WorkerService/WorkerService.csproj'
     
       - task: DotNetCoreCLI@2
         displayName: 'Build'
         inputs:
           command: 'build'
           projects: './examples/MicroserviceExample/WorkerService/WorkerService.csproj'
           arguments: '--configuration Release'
     
       - task: DotNetCoreCLI@2
         displayName: 'Publish'
         inputs:
           command: 'publish'
           projects: './examples/MicroserviceExample/WorkerService/WorkerService.csproj'
           arguments: '--configuration Release --output ./out'
     
       - task: Docker@2
         displayName: 'Build Docker image'
         inputs:
           command: 'build'
           Dockerfile: './examples/MicroserviceExample/WorkerService/Dockerfile'
           tags: 'opentelemetry-example-workerservice'
     

3. Define Docker Image Management: Ensure that Docker is set up correctly in your CI/CD tool, with permissions to build and push Docker images.

4. Environment Variables: Securely manage environment variables needed for the builds, such as database connection strings or API keys, using the secret management features of your CI/CD tool.

5. Set Up Deployment: Add deployment steps to your CI/CD configuration.

   • For GitHub Actions, include a job to deploy the Docker container:

     deploy:
       runs-on: ubuntu-latest
       needs: build
       steps:
         - name: Check out code
           uses: actions/checkout@v2
         
         - name: Login to Docker Hub
           run: echo "${{ secrets.DOCKER_HUB_PASSWORD }}" | docker login -u "${{ secrets.DOCKER_HUB_USERNAME }}" --password-stdin
         
         - name: Push Docker image
           run: docker push opentelemetry-example-workerservice
         ```
     

6. Testing: Integrate testing within your pipeline by adding steps for unit or integration tests, as applicable.

7. Monitor and Improve: Post-deployment, set up monitoring for your application to collect metrics and logs. Use OpenTelemetry to capture distributed traces for further insight.

8. Documentation: Update any necessary documentation for your team to understand the CI/CD workflows in place.

These steps provide a structured approach to implement CI/CD for the OpenTelemetry .NET project and ensure smooth deployment processes moving forward.

Quoting the provided docker configuration files and setup instructions informs the structure and handling of environments necessary for deployment activities within the project context.
