+# Ещё больше улучшений в конфиге CI/CD
+
+## 1. Добавляем helm linter и вывод манифестов.
+
+Добавляем новые шаги:
+
+```
+helm_lint:
+  stage: linter
+  image: centosadmin/kubernetes-helm:3.3.4
+  environment:
+    name: production
+  script:
+    - helm lint .helm
+        --set image=$CI_REGISTRY/$CI_PROJECT_NAMESPACE/$CI_PROJECT_NAME
+        --set imageTag=$CI_COMMIT_REF_SLUG.$CI_PIPELINE_ID
+  only:
+    - master
+```
+
+```
+template:
+  stage: template
+  image: centosadmin/kubernetes-helm:3.3.4
+  environment:
+    name: production
+  script:
+    - helm template $CI_PROJECT_PATH_SLUG .helm
+        --set image=$CI_REGISTRY/$CI_PROJECT_NAMESPACE/$CI_PROJECT_NAME
+        --set imageTag=$CI_COMMIT_REF_SLUG.$CI_PIPELINE_ID
+  only:
+    - master
+```
+
+Заносим их в список стейджей
+
+```
+stages:
+  - linter
+  - build
+  - test
+  - cleanup
+  - push
+  - template
+  - deploy
+```
+
+Или копируем готовый файл `.gitlab-ci.yml` в репозиторий xpaste.
+
+Пушим, смотрим результат.
+
+## 2. Самостоятельная работа
+
+Исправляем Error в выводе линтера, Warning можно пропустить.
+
+PS: В принципе можно убрать ключ `--debug` из шага deploy.
