| # При обычном коммите делает тег main (ветка) вместо latest. Логично, но некрасиво. Ниже изменения | |
| # 1. Применяет тег "latest", если текущий ref является тегом | |
| # 2. Применяет тег, основанный на имени ветки | |
| # 3. Применяет тег, основанный на хэше коммита | |
| # 4. Применяет тег, аналогичный тегу рефа, если текущий ref является тегом | |
| # Альтернативный вариант: https://github.com/strato-earth/workflow-task-template/blob/038f51662aff7e1b9fd6cf98c13e0e3ee8c65855/github/build.yml#L34-L44C17 | |
