Experience
Self-service Kubernetes for Internal Development Teams
I designed and implemented a self-service Kubernetes cluster provisioning platform to streamline internal development workflows. My goal was to provide development teams with an easy, consistent way to spin up disposable clusters for testing and development.
I gathered requirements from multiple teams, defined baseline configurations and common patterns, and built automation workflows with enough flexibility to support advanced use cases. I implemented the core interface using GitHub Actions, enabling developers to request new clusters by submitting a simple, schema-validated YAML file. Defaults ensured ease of use, while teams with higher demands could specify custom configurations within predefined limits.
I provisioned the underlying infrastructure using Terraform, deploying Amazon EKS clusters and supporting AWS resources, including VPC, S3, and IAM. To bootstrap base services into the clusters, I integrated Argo CD. I also implemented monitoring and cost-control mechanisms, feeding insights into Grafana dashboards and automating background processes to detect and clean up unused resources such as Amazon EBS and Amazon EC2. These optimizations helped manage capacity and reduce waste.
