[PATCH 3/5] fix: comprehensive code review and bug fixes - rollback/config.py: remove duplicate TYPE_CHECKING block and RollbackCallable alias; fix Version dataclass using bare defaults (now uses field(default_factory)) - rollback/handler.py: fix over-indented early-return guard in execute_rollback_version_files - rollback/signal.py: fix duplicate word in log message - rollback/command.py: fix inverted tree-prefix logic in list_rollback - scenario_plugins/abstract_scenario_plugin.py: remove stale krkn_config param from docstring; fix typos 'suceeded' and 'wating' - scenario_plugins/scenario_plugin_factory.py: move loaded_plugins and failed_plugins from class-level to instance-level to prevent shared state - scenario_plugins/native/plugins.py: add missing kraken_config parameter to Plugins.run() - scenario_plugins/native/native_scenario_plugin.py: pass kraken_config to PLUGINS.run() - scenario_plugins/hogs/hogs_scenario_plugin.py: fix has_selector always True, making random single-node selection unreachable - scenario_plugins/container/container_scenario_plugin.py: fix list.remove() return value bug (was assigning None to killed_container_list) - scenario_plugins/pod_disruption/pod_disruption_scenario_plugin.py: add missing return after namespace validation error - scenario_plugins/network_chaos_ng/network_chaos_ng_scenario_plugin.py: fix inverted random.sample condition (was sampling when count > len, crashing) - scenario_plugins/time_actions/time_actions_scenario_plugin.py: fix bare except clause referencing undefined variable e - scenario_plugins/service_hijacking, syn_flood, pvc: remove redundant inline imports inside static rollback methods - cerberus/setup.py: fix inverted logic in publish_kraken_status; fix local variable shadowing global check_application_routes in get_status; fix typo check_applicaton_routes - prometheus/client.py: fix variable shadowing in nested for k,v loops in metrics() - template_manager.py: fix chaos_scenarios wrapped as dict instead of list; remove unused optparse import; replace Values({}) with types.SimpleNamespace - utils/TeeLogHandler.py: move logs from class-level to instance-level - utils/HealthChecker.py: move current_iterations/ret_value to instance-level - utils/VirtChecker.py: move current_iterations/ret_value to instance-level - tests/rollback_scenario_plugins/simple.py: remove extra krkn_config param from run() signature - tests/test_rollback.py: fix TestScenarioPlugin.run() signature; remove krkn_config kwarg from run() call - tests/test_cerberus_setup.py: fix typo

-1. **Test in Non-Production**: Always test templates in development/staging environments first. -2. **Check Prerequisites**: Ensure all prerequisites are met for the target template. -3. **Monitor Resources**: Verify sufficient cluster resources are available. -4. **Backup Data**: Ensure critical data is backed up before running high-risk templates. - -### During Execution - -1. **Monitor Health**: Watch cluster and application health metrics. -2. **Check Logs**: Monitor KRKN and application logs for issues. -3. **Abort if Necessary**: Stop execution if unexpected issues occur. -4. **Document Results**: Record outcomes and observations. - -### After Execution - -1. **Verify Recovery**: Ensure all resources have recovered properly. -2. **Review Logs**: Analyze logs for insights and improvements. -3. **Update Configurations**: Adjust application configurations based on results. -4. **Document Learnings**: Record findings for future reference. - -## Risk Management - -### Risk Levels - -- **Low**: Minimal impact, unlikely to cause service disruption -- **Medium**: May cause temporary service disruption -- **High**: Can cause significant service disruption - -### Safety Measures - -1. **Start Small**: Begin with low-risk templates and low intensity settings. -2. **Gradual Increase**: Slowly increase intensity and complexity. -3. **Time Restrictions**: Run chaos experiments during maintenance windows. -4. **Rollback Plans**: Have clear rollback procedures ready. - -## Integration with CI/CD - -### GitHub Actions Example - -```yaml -- name: Run Chaos Test - run: | - python krkn-template run pod-failure \ - --param name_pattern="^app-.*$" \ - --param namespace_pattern="^testing$" -``` - -### Jenkins Pipeline Example - -```groovy -stage('Chaos Test') { - steps { - sh 'python krkn-template run network-latency --param latency="50ms"' - } -} -``` - -## Troubleshooting - -### Common Issues - -1. **Template Not Found**: Check template name spelling and templates directory path. -2. **Permission Denied**: Verify RBAC permissions for KRKN service account. -3. **Resource Not Found**: Ensure target resources exist and are accessible. -4. **Timeout Errors**: Increase timeout values for slow clusters. - -### Debug Mode - -Enable debug logging for detailed troubleshooting: - -```bash -python krkn-template run pod-failure --debug -``` - -### Log Locations - -- KRKN logs: Console output and report files -- Application logs: Kubernetes pod logs -- System logs: Node system logs (if accessible) - -## Contributing Templates - -### Creating New Templates - -1. Create directory under `templates/chaos-scenarios/` -2. Add `scenario.yaml`, `metadata.yaml`, and `README.md` -3. Follow the established structure and naming conventions -4. Test thoroughly before submitting - -### Template Guidelines - -- Use descriptive names and clear documentation -- Include comprehensive parameter descriptions -- Provide multiple usage examples -- Include troubleshooting sections -- Follow KRKN coding standards - -## Support - -For issues related to the template system: - -1.
