Simple Kubernetes management with GitLab

The tutorial simplifies the process of setting up and managing a Kubernetes cluster using infrastructure as code (IaC) in under 20 minutes, leveraging Terraform and Helm with GitLab CI/CD pipelines. It guides users through creating two IaC repositories: "gitlab-terraform-k8s" for provisioning and managing Kubernetes infrastructure via Terraform, and "cluster-management" for defining the desired state using the GitLab Agent for Kubernetes and Helm. Essential prerequisites include an AWS or GCP account, a GitLab account, and access to a GitLab Runner. The tutorial covers setting up the GitLab Terraform Kubernetes Template, registering the GitLab Agent, and adding cloud credentials to CI/CD variables for AWS EKS or GCP GKE. It also explains setting up the Kubernetes Cluster Management Project using a GitLab template and configuring the CI/CD pipeline to deploy applications like ingress, cert-manager, prometheus, and Vault. This approach allows comprehensive cluster management entirely through code, with the potential to deploy custom applications by updating the cluster-management helmfile.
