+```text
+
+FROM python:3.13.6-alpine
+
+WORKDIR /application
+
+COPY server.py /application
+
+COPY requirements.txt /application
+
+RUN pip install -r requirements.txt

+EXPOSE 5000

+CMD [ "python3", "server.py"]

+# 1. Plecam de la o imagine care are cat mai multe dependinte din ce ne trebuie noua
+# 2. Copiem fisierele necesare aplicatiei noastra
+# 3. Instalam eventuale dependinte
+# 4. Realizam eventuale configurari pentru a porni aplicatia
+# 5. Specificam comanda default care porneste aplicatie in momentul in care containerul este up and
+# running
