Add ValidCloudInitYaml validation rule to ensure cloud-init scripts are properly formatted before saving. The validator supports: - Cloud-config YAML (with or without #cloud-config header) - Bash scripts (starting with #!) - Empty/null values (optional field) Uses Symfony YAML parser to validate YAML syntax and provides detailed error messages when validation fails. Added comprehensive unit tests covering: - Valid cloud-config with/without header - Valid bash scripts - Invalid YAML syntax detection - Complex multi-section cloud-config Applied validation to: - ByHetzner component (server creation) - CloudInitScriptForm component (script management) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |
