* Docs(KEP): Go SDK for X-Definition Authoring (defkit) Introduces KEP proposal for defkit, a Go SDK that enables platform engineers to author X-Definitions using native Go code instead of CUE. Key proposed features: - Fluent builder API for Component, Trait, Policy, and WorkflowStep definitions - Transparent Go-to-CUE compilation - IDE support with autocomplete and type checking - Schema-agnostic resource construction - Collection operations (map, filter, dedupe) - Composable health and status expressions - Addon integration with godef/ folder support - Module dependencies for definition sharing via go get Signed-off-by: Anoop Gopalakrishnan <anoop2811@aol.in> * Fix(KEP): Examples and minor api changes given in the document Signed-off-by: Anoop Gopalakrishnan <anoop2811@aol.in> * Fix(KEP): align defkit examples - Fix golang version in CI - Fix variable declaration in example for testing - Add Is() comparison method to status check Signed-off-by: Anoop Gopalakrishnan <anoop2811@aol.in> * Docs(KEP): add security considerations section - Add goal #7 for secure code execution model - Add Security Considerations section covering: - Code execution model (compile-time only, not runtime) - Security benefits over CUE (static analysis, dependency scanning) - Threat model with mitigations Addresses PR feedback about code execution safety. Signed-off-by: Anoop Gopalakrishnan <anoop2811@aol.in> * Docs(KEP): add module versioning and definition placement sections - Add Module Versioning section explaining git-based version derivation - Add Definition Placement section covering: - Motivation for placement constraints in multi-cluster environments - Fluent API for placement (RunOn, NotRunOn, label conditions) - Logical combinators (And, Or, Not) - Module-level placement defaults - Placement evaluation logic - CLI experience for managing cluster labels - Add Module Hooks section for lifecycle callbacks - Minor fixes and clarifications throughout Signed-off-by: Anoop Gopalakrishnan <anoop2811@aol.in> * Docs(KEP): add module hooks and update addon integration sections - Add Module Hooks section covering: - Use cases (CRD installation, setup scripts, post-install samples) - Hook configuration in module.yaml (pre-apply, post-apply) - Hook types (path for manifests, script for shell scripts) - waitFor field with condition names and CUE expressions - CLI usage (--skip-hooks, --dry-run) - Update Addon Integration section with implementation details: - godef/ folder structure with module.yaml - CLI flags (--godef, --components, --traits, --policies, --workflowsteps) - Conflict detection and --override-definitions flag - Development workflow Signed-off-by: Anoop Gopalakrishnan <anoop2811@aol.in> * Docs(KEP): address PR review comments and clarify placement labels - Fix misleading "Sandboxed Compilation" claim (cubic-ai feedback) - renamed to "Isolated Compilation" and clarified that security relies on trust model, not technical sandboxing - Fix inconsistent apiVersion in module hooks example (defkit.oam.dev/v1 → core.oam.dev/v1beta1) - Clarify that placement uses vela-cluster-identity ConfigMap directly, not the vela cluster labels command (which is planned for future) - Add --stats flag to apply-module CLI documentation Signed-off-by: Anoop Gopalakrishnan <anoop2811@aol.in> * Docs(KEP): fix API documentation Signed-off-by: Anoop Gopalakrishnan <anoop2811@aol.in> * Docs(KEP): add forward-reference for RawCUE() escape hatch Signed-off-by: Anoop Gopalakrishnan <anoop2811@aol.in> --------- Signed-off-by: Anoop Gopalakrishnan <anoop2811@aol.in>
Introduction
KubeVela is a modern application delivery platform that makes deploying and operating applications across today's hybrid, multi-cloud environments easier, faster and more reliable.
Highlights
KubeVela practices the "render, orchestrate, deploy" workflow with below highlighted values added to existing ecosystem:
Deployment as Code
Declare your deployment plan as workflow, run it automatically with any CI/CD or GitOps system, extend or re-program the workflow steps with CUE. No ad-hoc scripts, no dirty glue code, just deploy. The deployment workflow in KubeVela is powered by Open Application Model.
Built-in observability, multi-tenancy and security support
Choose from the wide range of LDAP integrations we provided out-of-box, enjoy enhanced multi-tenancy and multi-cluster authorization and authentication, pick and apply fine-grained RBAC modules and customize them as per your own supply chain requirements. All delivery process has fully automated observability dashboards.
Multi-cloud/hybrid-environments app delivery as first-class citizen
Natively supports multi-cluster/hybrid-cloud scenarios such as progressive rollout across test/staging/production environments, automatic canary, blue-green and continuous verification, rich placement strategy across clusters and clouds, along with automated cloud environments provision.
Lightweight but highly extensible architecture
Minimize your control plane deployment with only one pod and 0.5c1g resources to handle thousands of application delivery. Glue and orchestrate all your infrastructure capabilities as reusable modules with a highly extensible architecture and share the large growing community addons.
