Необходимо достать отсюда только первый столбец, преобразовав его строки, из формата demomed-analysis-service-6f955bff79-cqjv9 должно получиться demomed-analysis-service, только там, где это необходимо. Достать только первый столбец получилось без проблем, а вывести его строки без лишнего не получается. Помогите пожалуйста :)
