Introduction
Continuous Integration (CI) and Continuous Deployment (CD) have become essential practices in modern software development. In the context of Go projects, CI/CD pipelines can help automate tasks such as testing, building, and deploying your applications. In this blog post, we will explore how to set up CI/CD for Go projects using popular tools like GitHub Actions and Jenkins.
Setting up CI with GitHub Actions
GitHub Actions is a powerful tool for automating workflows on GitHub repositories. To set up a CI pipeline for your Go project, you can create a .github/workflows/ci.yml file in your repository. Here’s an example workflow that runs tests on your Go code:
1

name: CI
on:
push:
branches: [main]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Set up Go
uses: actions/setup-go@v2
with:
go-version: 1.17
- name: Run tests
run: go test ./...
In this workflow, we specify that the CI job should run on every push to the main branch. The job sets up the Go environment using the actions/setup-go action and then runs tests using the go test command.
Setting up CD with Jenkins
Jenkins is a popular open-source automation server that can be used to set up CI/CD pipelines for your Go projects. To set up a CD pipeline for your Go project, you can create a Jenkins pipeline script. Here’s an example pipeline that builds and deploys a Go application:
1

pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'go build -o app'
}
}
stage('Deploy') {
steps {
sh 'scp app user@server:/path/to/deployment'
}
}
}
}
In this pipeline, we define two stages: Build and Deploy. The Build stage builds the Go application using the go build command, and the Deploy stage deploys the built application to a server using the scp command.
Conclusion
Setting up CI/CD pipelines for your Go projects can help improve the quality and efficiency of your development process. By automating tasks such as testing and deployment, you can ensure that your applications are always up-to-date and functioning correctly. Whether you choose to use GitHub Actions, Jenkins, or another CI/CD tool, the key is to streamline your development workflow and make it as efficient as possible.
