GitHub Actions comparison in Jenkins - Commands & Configuration

Introduction

GitHub Actions and Jenkins are tools that help automate tasks like testing and deploying code. They solve the problem of doing these tasks manually, which can be slow and error-prone.

When you want to automatically test your code every time you save changes.

When you need to deploy your app to a server without doing it by hand.

When you want to run simple automation directly inside GitHub without extra servers.

When you have complex workflows that need many steps and plugins.

When you want to share automation scripts easily with your team.

Commands

Check the installed Jenkins version to ensure Jenkins is set up correctly.

Terminal

jenkins --version

Expected Output

2.387.1

List GitHub Actions workflows in the current repository to see what automation is available.

Terminal

gh workflow list

Expected Output

build.yml

deploy.yml

test.yml

Trigger a Jenkins pipeline named 'example-pipeline' to run the automation defined there.

Terminal

jenkins-cli build example-pipeline --wait

Expected Output

Started build #15

Waiting for build to complete...

Build #15 SUCCESS

→

--wait - Wait for the build to finish before returning

Show recent GitHub Actions runs to check the status of automated workflows.

Terminal

gh run list

Expected Output

1234567890abcdef build.yml completed success

abcdef1234567890 deploy.yml completed failure

Key Concept

If you remember nothing else from this pattern, remember: GitHub Actions is tightly integrated with GitHub for simple automation, while Jenkins offers more customization and control for complex pipelines.

Common Mistakes

Trying to run Jenkins commands without Jenkins server running

Jenkins CLI requires the Jenkins server to be up and accessible to work.

Start the Jenkins server before running Jenkins CLI commands.

Assuming GitHub Actions workflows run outside GitHub

GitHub Actions run inside GitHub's infrastructure and require the repository to be on GitHub.

Use GitHub Actions only with repositories hosted on GitHub.

Summary

Use 'jenkins --version' to verify Jenkins installation.

Use 'gh workflow list' to see GitHub Actions workflows in a repo.

Trigger Jenkins pipelines with 'jenkins-cli build' and wait for completion.

Check GitHub Actions run status with 'gh run list'.
