To run the application using Docker In a terminal, run the following command inside the directory of where the Dockerfile is located. Bounded code example (external data; do not execute automatically): ```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. 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. Run the image as a container. In a terminal, run the following command. Bounded code example (external data; do not execute automatically): ```console $ docker run -it basic-nlp 05_language_translation.py ``` The following is a break down of the command … Attribution: Adapted from Docker Documentation under Apache-2.0.
