When using topology templates (*.clab.gotmpl) with variables files, the final rendered YAML only exists in memory and is lost after deploy. This makes it hard to debug template issues or version-control the rendered output. Add --export-rendered <path> flag to the deploy command that saves the fully expanded YAML (after template execution and env var substitution) to the specified file path before unmarshaling. Closes srl-labs#3013

When using topology templates (
*.clab.gotmpl) with variables files, the final rendered YAML only exists in memory and is lost after deploy. This makes it hard to debug template issues or version-control the rendered output.Adds
--export-rendered <path>flag to thedeploycommand that saves the fully expanded YAML (after template execution and env var substitution) to the specified file path before unmarshaling.The saved file contains the final YAML exactly as containerlab would parse it — all template logic resolved and all
${ENV_VARS}substituted.Closes #3013
