Integrating Helm Charts in GitLab

Integrate Helm Charts in GitLab Pipelines & Streamline Your Application Deployments

Introduction:

As organizations embrace cloud-native architectures and containerization, deploying applications efficiently and consistently becomes paramount. Helm, a popular package manager for Kubernetes, simplifies the deployment and management of applications by defining and managing Kubernetes resources as charts. GitLab, a powerful DevOps platform, offers robust CI/CD capabilities with its pipelines feature. By integrating Helm charts into GitLab pipelines, you can automate the deployment of your applications, enabling seamless and reliable releases. In this article, we will explore the steps to integrate Helm charts into GitLab pipelines and reap the benefits of streamlined application deployments.
