🚀 How to Build & Push Express.js API to GitLab Private Registry | GitLab CI/CD Series Ep. 09 🔥

Welcome to Episode 09 of our GitLab CI/CD Mastery Series! 🎉 In this exciting tutorial, we’ll walk you through creating a robust CI/CD pipeline using GitLab CI to build and push your Express.js REST API Docker image to GitLab's Private Container Registry. Whether you're a beginner or looking to level up your DevOps skills, this video will show you how to streamline your workflow with GitLab's powerful CI/CD features.

In this episode, we’ll cover the following topics:

Writing and structuring the .gitlab-ci.yml pipeline to automate the build process.
Building a Docker image for your Express.js REST API directly in GitLab CI/CD.
Pushing the built Docker image to your GitLab Private Container Registry for secure storage and easy access.
Setting up Docker authentication to interact with the GitLab container registry.
Optimizing the pipeline for faster builds and automated deployment.
With GitLab CI/CD, you can automate your entire development lifecycle — from code commit to deployment — and in this episode, we show you how to integrate Docker into that pipeline, ensuring that your API is always built, tested, and deployed efficiently.
