GitOps with GitLab: Turn a GitLab agent for Kubernetes installation to manage itself

The blog post series explores using GitLab as a GitOps tool, focusing on managing Kubernetes deployments with a GitLab agent. The article builds on previous tutorials, guiding users to self-manage a GitLab agent for Kubernetes, enabling it to handle its deployment and upgrades within a GitOps framework. This approach offers benefits such as code-based management, facilitating processes like Merge Requests and approvals, and simplifying upgrades by managing agent configurations in code. The tutorial explains using kpt and kustomize for managing deployment manifests and Bitnami's Sealed Secrets for secure secret management. It highlights the role of inventory policies in managing resources and the importance of appropriate role-based access control (RBAC) settings. Finally, the article demonstrates automating deployment updates through GitOps pipelines and provides an example of upgrading agent deployments by modifying version settings, emphasizing the streamlined management of multiple deployments. This installment concludes the series on GitOps with GitLab.
