Final answer:
To create a Docker container, use the ‘docker run’ command with the image name and optional commands and arguments. If the image is not available locally, Docker will pull it from the registry. Customize the container creation with additional options as needed.
Step-by-step explanation:
To create a Docker container from an image, you need to execute a command via the Docker CLI (Command Line Interface). The basic syntax for creating a container is docker run [OPTIONS] IMAGE [COMMAND] [ARG...]. Here are the steps you typically follow:
- Choose a Docker image that you want to use for your container. You can find Docker images on Docker Hub or create your own.
- Open a terminal on your computer.
- Type the docker run command followed by the name of the image. For example, if you're creating a container from the latest Ubuntu image, you would enter docker run -it ubuntu /bin/bash to run an interactive bash shell within the container.
- If necessary, customize the command with additional options like port mapping (-p) if you need to access network services on the container, or mount volumes (-v) to persist data.
Once the command is executed, Docker will create a new container from the specified image. If the image is not available locally, Docker will attempt to pull it from the configured registry, such as Docker Hub.
