Deploying GitLab with Helm on Kubernetes: A Guide

Deploying GitLab with Helm on Kubernetes: A Guide

As data scientists, we constantly seek to streamline our workflows and enhance our productivity. One such way is by deploying GitLab with Helm on Kubernetes. This guide will walk you through the process, ensuring you can leverage the power of these tools to supercharge your data science projects.

What is GitLab, Helm, and Kubernetes?

GitLab is a web-based DevOps lifecycle tool that provides a Git-repository manager, providing wiki, issue-tracking, and continuous integration/continuous deployment pipeline features.

Helm is a package manager for Kubernetes that allows developers and operators to more easily package, configure, and deploy applications and services onto Kubernetes clusters.

Kubernetes is an open-source platform designed to automate deploying, scaling, and operating application containers.

Why Deploy GitLab with Helm on Kubernetes?

Deploying GitLab on Kubernetes using Helm offers several benefits:

• Scalability: Kubernetes can automatically scale your applications based on resource usage or custom metrics.
• High Availability: Kubernetes ensures that your applications are always available to your users.
• Rolling Updates & Rollbacks: Kubernetes can update your applications without downtime and roll back to previous versions if something goes wrong.

Prerequisites

Before we start, ensure you have the following:

• A Kubernetes cluster up and running.
• Helm installed on your local machine and Tiller on your Kubernetes cluster.
• kubectl installed on your local machine.

Step-by-Step Guide to Deploy GitLab with Helm on Kubernetes

Step 1: Add the GitLab Helm Chart Repository

First, we need to add the GitLab Helm chart repository to our Helm client. Run the following command:

helm repo add gitlab https://charts.gitlab.io/

Step 2: Update Helm

Next, update Helm to ensure you have the latest charts from the GitLab repository:

helm repo update

Step 3: Configure GitLab

Now, we need to configure GitLab. Create a gitlab.yaml file and add the following content:

global:
  gitlab:
    host: gitlab.example.com
    https: true
certmanager-issuer:
  email: admin@example.com

Replace gitlab.example.com with your domain and admin@example.com with your email.

Step 4: Install GitLab

Finally, we can install GitLab using the Helm chart:

helm upgrade --install gitlab gitlab/gitlab \
  -f gitlab.yaml \
  --timeout 600s \
  --set global.hosts.domain=example.com \
  --set certmanager-issuer.email=admin@example.com

Replace example.com with your domain and admin@example.com with your email.

Step 5: Verify the Installation

To verify the installation, run:

kubectl get services

You should see GitLab running.

Conclusion

Deploying GitLab with Helm on Kubernetes is a powerful way to streamline your data science workflows. It provides scalability, high availability, and seamless updates and rollbacks. With this guide, you should be able to deploy GitLab on your Kubernetes cluster and start leveraging these benefits.
