   - `docker build`: This is the primary command used to build a Docker image
     from a Dockerfile and a context. The context is typically a set of files at
     a specified location, often the directory containing the Dockerfile.
   - `-t basic-nlp`: This is an option for tagging the image. The `-t` flag
     stands for tag. It assigns a name to the image, which in this case is
     `basic-nlp`. Tags are a convenient way to reference images later,
     especially when pushing them to a registry or running containers.
   - `.`: This is the last part of the command and specifies the build context.
     The period (`.`) denotes the current directory. Docker will look for a
     Dockerfile in this directory. The build context (the current directory, in
     this case) is sent to the Docker daemon to enable the build. It includes
     all the files and subdirectories in the specified directory.

   For more details, see the [docker build CLI reference](/reference/cli/docker/buildx/build/).

   Docker outputs several logs to your console as it builds the image. You'll
   see it download and install the dependencies. Depending on your network
   connection, this may take several minutes. Docker does have a caching
   feature, so subsequent builds can be faster. The console will
   return to the prompt when it's complete.

2. Run the image as a container.

   In a terminal, run the following command.

   ```console
   $ docker run -it basic-nlp 03_text_classification.py
   ```

   The following is a break down of the command:

   - `docker run`: This is the primary command used to run a new container from
     a Docker image.
   - `-it`: This is a combination of two options:
     - `-i` or `--interactive`: This keeps the standard input (STDIN) open even
       if not attached. It lets the container remain running in the
       foreground and be interactive.
     - `-t` or `--tty`: This allocates a pseudo-TTY, essentially simulating a
       terminal, like a command prompt or a shell. It's what lets you
       interact with the application inside the container.
   - `basic-nlp`: This specifies the name of the Docker image to use for
     creating the container. In this case, it's the image named `basic-nlp` that
Title: Building and Running the Docker Image
Summary
Docker outputs logs during the build process, showing dependency downloads and installations. The caching feature can speed up subsequent builds. Then, the process of running the image as a container is explained using the `docker run` command. The command breakdown includes the function of `docker run`, the combination of `-it` options for interactive and TTY allocation, and the specification of the `basic-nlp` image for creating the container.
