k8s-launch-kit-dryrun
Use this skill when the user wants to preview what k8s-launch-kit (l8k) would deploy without making changes, or wants to safely validate their configuration before applying. Activate for: dry-run, preview, validation, 'what would happen if', testing configurations, schema discovery, checking generated manifests, or any cautious pre-deployment step. Also use when the user asks 'is my config valid' or 'show me what would be created' -- even without mentioning dry-run explicitly.

# l8k: Dry Run & Validation
> **PREREQUISITE:** Read `../k8s-launch-kit-shared/SKILL.md` for install paths, global flags, and output modes.
Preview what l8k would deploy without making cluster changes, or validate a configuration.
## Usage
```bash
# Generate-only (no --deploy, no cluster changes)
l8k generate --user-config <CONFIG> --fabric <FABRIC> --deployment-type <TYPE> \
--save-deployment-files <DIR>
# Dry-run with deploy flag (validates against live cluster but doesn't apply)
l8k generate --user-config <CONFIG> --fabric <FABRIC> --deployment-type <TYPE> \
--save-deployment-files <DIR> --deploy --dry-run [--kubeconfig <PATH>]
```
## Modes
| Mode | Flags | Cluster Access | What It Does |
|------|-------|----------------|--------------|
| Generate-only | No `--deploy` | Not needed | Renders templates, writes YAMLs to disk |
| Dry-run | `--deploy --dry-run` | Needed | Generates + validates against cluster, doesn't apply |
## Examples
```bash
# Preview generated files (no cluster needed)
l8k generate --user-config cluster-config.yaml \
--fabric ethernet --deployment-type sriov \
--save-deployment-files ./output
# Dry-run against live cluster
l8k generate --user-config cluster-config.yaml \
--fabric ethernet --deployment-type sriov \
--save-deployment-files ./output \
--deploy --kubeconfig ~/.kube/config --dry-run
# Agent mode: get manifest list as JSON
l8k generate --user-config cluster-config.yaml \
--fabric ethernet --deployment-type sriov \
--save-deployment-files ./output \
--deploy --dry-run --kubeconfig ~/.kube/config \
--output json
# Schema discovery (list capabilities)
l8k schema
```
## JSON Output (Dry-Run)
```json
{
"success": true,
"phase": "generate",
"profile": {"fabric": "ethernet", "deployment": "sriov"},
"generatedFiles": ["output/network-operator/10-nicclusterpolicy.yaml", "output/.l8k/resolved-config.yaml"],
"deployed": false,
"dryRun": true
}
```
## Tips
- Generate-only is the safest starting point — inspect the YAMLs before applying.
- Use `l8k schema` to programmatically discover available profiles and flags.
- Combine `--dry-run --output json` for CI validation gates.

## OpenShift
For OpenShift, use `--flavor ocp`; NV-IPAM IPPool validation may be deferred because its CRD appears only after live NCP reconciliation. A deferred check is not a pass.
