Modern, composable deployment engine #12996

Overview

Track the work required to make the Radius deployment engine modern, composable, and usable consistently from CI/CD systems, GitOps controllers, and agents.

This initiative covers:

• Supported deployment integration with GitHub Actions
• Pull-based deployment through GitOps and Argo CD
• Portable deployable artifacts
• Dry-run / "what if" deployment plans
• Stable deployment primitives for agents and automation

Outcomes

• Radius applications can be built independently from the environment where they are deployed.
• GitHub Actions and Argo CD use documented, supported Radius contracts.
• Users can inspect expected deployment changes before resources are mutated.
• Agents can build, plan, deploy, and monitor applications without parsing human-oriented terminal output.
• Artifact, plan, and operation formats are versioned, machine-readable, and safe for automation.

Completion criteria

• Each capability is covered by an approved specification or an implementation issue with testable completion criteria.
• GitHub Actions and Argo CD reference supported Radius deployment contracts.
• A portable artifact can be produced and deployed in separate processes.
• A deployment plan reports expected changes without mutating deployment state.
• Agent-facing operations expose structured results, errors, and status.
• End-to-end documentation demonstrates the supported CI/CD, GitOps, and agent workflows.
