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

# 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

# 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 --yes 2>/dev/null
