+# Лабораторная 2
+## Вариант 9
+
+## Задание
+Разработать два приложения такие, что результат первого является исходными данными для второго.
+
+Описание задач двух программ:
+- Берёт из каталога /var/data случайный файл и перекладывает его в /var/result/data.txt.
+- Ищет наибольшее число из файла /var/data/data.txt и сохраняет его вторую степень в /var/result/result.txt.
+
+## Описание Программы
+
+### Как запустить?
+
+```docker compose up -d```
+
+### Созданные файлы:
+
+**Dockerfile**
+
+Они идентичны
+
+```
+FROM python:3.11
+WORKDIR /app
+COPY . .
+CMD ["python", "worker_1.py"]
+```
+**docker-compose**
+
+```
+version: "3"
+services:
+  worker1:
+    build:
+      context: ./worker1
+      dockerfile: Dockerfile
+    volumes:
+      - ./data:/var/data
+      - ./result:/var/result
+
+  worker2:
+    depends_on:
+      - worker1
+    build:
+      context: ./worker2
+      dockerfile: Dockerfile
+    volumes:
+      - ./result:/var/data
+      - ./result:/var/result
+
+```
+
+**Исходные файлы**
+
+Файлы содержат абсолютно рандомные числа:
