-Images are normally built (or "bootstrapped") from a base image indicated by `FROM`. This base image is composed of one or more layers that will be pulled from the appropriate [container registry](registries.md) during buildtime. In this example, version 22.04 of the Ubuntu operating system is specified as the base image. Docker pulls from Ubuntu's [DockerHub container registry](https://hub.docker.com/_/ubuntu) by default. The ability to use a different base image provides a way to use packages which may work more easily on a specific operating system distribution. For example, the Linux distribution on Kestrel is CentOS, so building the above image would allow the user to install packages from Ubuntu repositories.

 The `RUN` portion of the above Dockerfile indicates the command to run *during the image's buildtime*. In this example, it installs the Python 3 package. Additional commands such as `COPY`, `ENV`, and others enable the customization of your image to suit your compute environment requirements.
