May 1, 2026

May 2026 monthly highlights across harness-go-sdk and terraform-provider-harness focusing on QoS-enabled autostopping and configuration hygiene. Key features delivered include priority-driven autostopping scheduling and a user-controllable priority attribute for fixed schedules, with cross-repo dependency alignment. Major cleanup work also updated documentation/configuration to reduce misconfig risks.

April 2026: Delivered Autostopping Rules Custom Domain Support in harness/terraform-provider-harness, enabling custom domain configuration for Instance, ECS, and Scale group autostopping rules. This enhances deployment flexibility, aligns autostopping behavior with domain routing strategies, and reduces manual configuration. Included a focused fix CCM-32143 to ensure custom domains are applied only to the intended rule types.

Feb 1, 2026

February 2026 monthly summary for the harness-go-sdk and Terraform provider harness teams. This period delivered substantial AutoStopping enhancements, drift detection improvements, and expanded IaC capabilities, driving reliability, security, and business value across platforms. Key features delivered: - AutoStopping API Suite: Added V2 Get API for autostopping rules with x-api-key authentication and improved response structure; introduced Autostopping Alerts API (create/update/delete/retrieve) with API key authentication and documentation. This enhances monitoring, alerting, and secure access. - Drift detection and resource schema improvements: Implemented drift detection for VM resources and autostopping load balancer/proxy resources; cleaned up resource parameters to improve accuracy; deprecated/removal of hostname parameter for LB/proxy resources; API/data structure updates to reflect state. - Flexible autostopping rule configuration: Added tag-based autostopping rule creation and a new path parameter to support routing options based on tags or VM IDs. - Kubernetes (K8s) AutoStopping Rules support: Terraform provider now supports Kubernetes-based autostopping rules with new resources/data sources, schemas, and YAML validation. - Autostopping alerts and connectivity enhancements: Added alert management (email/Slack) for rule events; exposed TCP ports as Terraform outputs and introduced a connect block to manage source ports for SSH/RDP and custom TCP ports for VM rules. Major bugs fixed: - Stabilized API behavior and documentation by implementing API key authentication and correcting swagger header handling for the V2 APIs. - Fixed alert entity structure and base path issues in the Autostopping Alerts API, improving reliability of create/read/update/delete flows. - Various cleanup commits addressing dependencies and consistency across the go modules and SDKs to ensure stable builds. Overall impact and accomplishments: - Strengthened security and access control for AutoStopping APIs through API key authentication and better documentation. - Increased reliability and accuracy of state tracking via drift detection and cleaned resource schemas. - Expanded IaC capabilities with tag-based rule configuration, Kubernetes support, and richer networking outputs, enabling faster implementation and safer changes. - Enhanced operational visibility through alerts and improved telemetry around autostopping events. Technologies/skills demonstrated: - Go (SDK) development, API design, authentication mechanisms, and API documentation. - Terraform provider development, resource/schema design, and data source implementations. - Terraform outputs/connect blocks for server connectivity and port management. - Kubernetes rule support, YAML validation, and provider integration. - CI/CD-ready code changes and multi-repo coordination across harners-go-sdk and terraform-provider-harness.

November 2025: Delivered Terraform AutoStopping rules for Auto Scaling Groups in harness/terraform-provider-harness. Implemented new resources and data sources to configure and retrieve ASG AutoStopping rules, aligned with CCM-27128. Registered new resource harness_autostopping_rule_scale_group and integrated provider wiring, docs, and tests. This enables automated idle-instance management, cost optimization, and improved governance for Terraform-managed deployments. Demonstrated Terraform provider development, resource/data-source modeling, and end-to-end test coverage.
