Continuous Integration/Continuous Deployment - open-telemetry/opentelemetry-dotnet

Continuous Integration/Continuous Deployment (CI/CD) is a critical practice in modern software development that enables automated building, testing, and deployment of applications. This section will discuss managing CI/CD for the OpenTelemetry.NET project, which is an open-source automatic instrumentation library for .NET applications.

CI/CD Options for OpenTelemetry.NET

  1. GitHub Actions: GitHub Actions is a popular CI/CD tool integrated with GitHub, making it a natural choice for OpenTelemetry.NET, which is hosted on GitHub. The OpenTelemetry.NET project uses GitHub Actions for its CI/CD pipelines, as shown in their GitHub repository (https://github.com/open-telemetry/opentelemetry-dotnet).

Here’s an example of a GitHub Actions workflow for building and testing the OpenTelemetry.NET project:

name: Build and Test

on:
push:
branches: [ main ]
pull_request:
types: [ opened, synchronize, reopened ]

jobs:
build-and-test:
runs-on: windows-latest

steps:
- uses: actions/checkout@v2

- name: Setup .NET SDK
uses: actions/setup-dotnet@v2
with:
dotnet-version: 6.0.x

- name: Restore dependencies
run: dotnet restore

- name: Build
run: dotnet build --configuration Release

- name: Test
run: dotnet test --configuration Release

This workflow runs on push and pull request events, performing build, test, and other tasks.

  1. Azure Pipelines: Another option for managing CI/CD for OpenTelemetry.NET is Azure Pipelines. Azure Pipelines is a cloud-based CI/CD service that works with any language, platform, or cloud. It offers tight integration with GitHub and other version control systems.

Here’s an example of an Azure Pipelines YAML configuration for building and testing the OpenTelemetry.NET project:

trigger:
branches:
include:
- main

pool:
vmImage: 'windows-latest'

steps:
- task: UseDotNet@2
inputs:
packageType: 'sdk'
version: '6.0.x'

- script: |
dotnet restore
dotnet build --configuration Release
displayName: 'Restore and Build'

- script: |
dotnet test --configuration Release
displayName: 'Test'

This configuration runs on the main branch, sets up the .NET SDK, restores dependencies, builds, and tests the project.

  1. GitLab CI/CD: GitLab CI/CD is another CI/CD tool that can be used for managing OpenTelemetry.NET’s CI/CD pipelines. GitLab CI/CD offers a seamless experience for GitLab users, with tight integration with GitLab repositories.

Here’s an example of a GitLab CI/CD configuration for building and testing the OpenTelemetry.NET project:

stages:
- build
- test

build_job:
stage: build
image: mcr.microsoft.com/dotnet/sdk:6.0
script:
- dotnet restore
- dotnet build --configuration Release

test_job:
stage: test
image: mcr.microsoft.com/dotnet/sdk:6.0
script:
- dotnet test --configuration Release

This configuration defines two stages, build and test, and performs the respective tasks for the OpenTelemetry.NET project.

Conclusion

OpenTelemetry.NET can be integrated with various CI/CD tools, including GitHub Actions, Azure Pipelines, and GitLab CI/CD. Each tool offers unique features and benefits, allowing teams to choose the one that best fits their needs and preferences. The OpenTelemetry.NET project currently uses GitHub Actions for its CI/CD pipelines, as shown in their GitHub repository.
