Building and Running the Docker Image

editor. As the sample contains several applications, the script lets you specify which application to run when the container starts. ## Run the application To run the application using Docker: 1. Build the image. In a terminal, run the following command inside the directory of where the `Dockerfile` is located. ```console $ docker build -t basic-nlp . ``` The following is a break down of the command: - `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 02_name_entity_recognition.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

This section details how to build the Docker image using the `docker build` command, explaining the command's components such as the `-t` tag and the build context (`.`). It also mentions the Docker build process and the caching feature for faster subsequent builds. The section then moves on to running the built image as a container using the `docker run` command, breaking down the command's options, including `-it` for interactive mode.
