Github Vs Gitlab Vs Argo Workflow

As developers strive to deliver high-quality code at a rapid pace, the use of CI/CD pipelines has become increasingly essential. CI/CD Pipelines automate the process of building, testing, and deploying software, enabling teams to streamline their development workflows and deliver value to customers quickly. While there could be several version control systems that allow seamless CI/CD pipeline automation, GitLab and Argo Workflow are some of the most popular CI/CD platforms. GitHub, on the other hand, is a leading version control system that provides Github Actions as a strong CI/CD tool. Each platform has its strengths and features, making them suitable for different use cases and project requirements. In this article, we will explore the capabilities of each platform and compare them in the context of building Continuous Integration and Continuous Deployment pipelines for faster software releases. Also, we will discuss how engineering platforms like Atmosly further make your application deployment pipelines easier, faster, and more secure.

Github, Gitlab, and Argo Workflow Comparison 

Below are comparison metrics or factors you should watch out for;

Combining Argo Workflow and ArgoCD

By definition, ArgoCD is a declarative, GitOps continuous delivery tool for Kubernetes. It allows you to maintain and manage Kubernetes resources using Git repositories as the source of truth for the declared desired states of applications. Typically, ArgoCD simplifies application deployment, configuration management, and GitOps practices.  But what makes ArgoCD truly compelling is its ability to integrate seamlessly with other tools like GitHub, GitLab, and Argo Workflows. WIth ArgoCD, you can build your Kubernetes workflow. 

ArgoCD offers you the following features that would be beneficial:

GitOps Model:

• ArgoCD follows the GitOps model, where desired configuration changes are pushed to Git repositories.
• The cluster state automatically syncs to the desired state defined in Git.
• This ensures consistency and traceability.

Declarative Configuration Synchronization:

• ArgoCD synchronizes application state with declarative configuration stored in Git.
• Any drift between desired and actual states is automatically corrected.

Web User Interface (UI) and CLI:

• ArgoCD provides both a visual web UI and a command-line interface (CLI).
• The UI allows easy management of applications and monitoring of sync status.

Configuration Drift Detection:

• ArgoCD detects configuration drift and alerts when the actual state deviates from the desired state.
• It helps maintain consistency across environments.

Role-Based Access Control (RBAC):

• Fine-grained RBAC ensures secure multi-cluster management.
• Control who can manage applications and access resources.

Single Sign-On (SSO):

• ArgoCD integrates with identity providers (e.g., GitLab, GitHub, OAuth2).
• Users log in using existing credentials.

Webhooks for Automation:

• ArgoCD supports webhooks triggered by Git events.
• Automate synchronization and deployment based on changes.

Integration with CI Pipelines:

• ArgoCD seamlessly integrates with existing CI/CD pipelines.
• It automates application deployment based on GitOps workflows.

Setting up your first Gitlab pipeline:

In this tutorial, we'll walk through the process of creating a new project in GitLab and pushing your first file to the repository.

1. Log in to GitLab

First, log in to your GitLab account at gitlab.com.

2. Create a New Project

Once logged in, create a new project by clicking on the "New project" button. Choose a name for your project, add a description, and select whether you want it to be private or publicly visible.

3. Configure Git

Open your Git Bash and configure your user name and email ID using the following commands:

git config --global user.name "Your Name"
git config --global user.email "your.email@example.com"

4. Create a Local Repository

Create a new directory for your project and navigate into it:

mkdir my-project
cd my-project

5. Initialize a Git Repository

Initialize a Git repository in your project folder:

git init

6. Create a New File

Create a new file in your project folder. For example, you can create a text file using the following command:

touch input.txt

7. Add and Commit Changes

Add the new file to the staging area and commit it to the repository:

git add .
git commit -m "Add input.txt"

8. Push to GitLab

Push your changes to the GitLab repository. Copy the remote repository URL from your GitLab project page and use it in the following command:

git remote add origin <repository-url>

3. Creating Your First Workflow

To create a new workflow, you'll need to define a workflow template in YAML format. Here's an example of a simple workflow that runs a single job:

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
 generateName: hello-world-
spec:
 entrypoint: whalesay
 templates:
 - name: whalesay
 container:
 image: docker/whalesay
 command: [cowsay]
 args: ["Hello, Argo Workflows!"]

Save this YAML file as hello-world.yaml and submit it to Argo Workflows:

“argo submit hello-world.yaml”

4. Monitoring Your Workflow

You can monitor the progress of your workflow using the Argo Workflows UI or the command line. To list all running workflows, use the following command:

argo list

To get more detailed information about a specific workflow, use the following command:

argo get <workflow-name>

5. Advanced Workflow Features

Argo Workflows supports many advanced features, such as parallelism, conditionals, and loops. You can use these features to create complex workflows that orchestrate multiple jobs.

6. Integrating with Other Tools

Argo Workflows can be integrated with other tools and services to further automate your workflows. For example, you can use Argo Events to trigger workflows based on external events, or use Argo CD to automatically deploy your application after a successful workflow run.
