Building a Deployment Platform on Self-Managed Infrastructure with k3s

Short summary

Infrastructure team consolidated production workloads from AWS, Contabo, and GoDaddy onto a unified k3s-based platform to reduce costs and standardize deployment workflows. GitHub Actions enforced consistent CI across repositories, while Ansible automated server provisioning and cluster setup. They built a custom Go-based operator to replace Helm, simplifying deployment definitions from repetitive YAML to code-driven abstractions.

• •Consolidated multi-cloud infrastructure (AWS, Contabo, GoDaddy) to k3s cluster for cost reduction
• •Standardized CI/CD with GitHub Actions, making deployment validation consistent across repos
• •Automated provisioning with Ansible; built custom Go operator to replace Helm templates
