GitLab CI/CD on Google Kubernetes Engine in 15 minutes or less

What this post added

This post details the integration of GitLab CI/CD with Google Kubernetes Engine (GKE). It outlines the prerequisites for this integration, including a configured GitLab instance with Google OAuth2 OmniAuth Provider and a Google Cloud project with necessary APIs enabled. The post provides a step-by-step guide for administrators to add a Kubernetes cluster on GKE, install Helm Tiller, and then install the GitLab Runner application on the cluster. This enables shared runners for CI pipelines directly on GKE, with guidance on configuring the number of nodes for simultaneous job execution.
