What commands are typically used in the command line to define the build process of a container in a Dockerfile?

In a Dockerfile, the following instructions are usually used to define the container build process:

• FROM — specifies the base image from which to start the build.
• RUN — executes commands during the build process (e.g., installing packages).
• COPY or ADD — copies files from the build context into the image.
• CMD — sets the command to be executed when the container starts.
• ENTRYPOINT — sets the entry point for the container.
• ENV — sets environment variables.
• WORKDIR — sets the working directory inside the container.

Example:

FROM python:3.9-slim
WORKDIR /app
COPY requirements.txt ./
RUN pip install -r requirements.txt
COPY . .
CMD ["python", "app.py"]
