Run a Docker image

Creates a container and runs an image in it.

sp_docker_run(image_tag, options = "", command = "", args = "")

Arguments

image_tag	character: a valid image tag (name) for the docker image. If it doesn't exist locally, `docker run` will try to download it. If the download then fails, the function will stop with an error message. Note that the full syntax of an image tag is `<repository>/<name>:<tag>`. For example, the PostgreSQL 10 image we use is `docker.io/postgres:10`.
options	character: the options to use when running the image. Default is the empty string. You will usually need at least the `--name` option to give the container a name.
command	character: the command to run after the container boots up. Default is an empty string, which uses the startup command defined in the image.
args	character: the arguments for the command. Default is an empty string.

Result of Docker command if it succeeded. Stops with an error message if it failed.

Do docker run --help in a command prompt to see all the options, of which there are many.
