Try setting must_run = false in docker_container.foo

[Junkern]

The behaviour is expected and not an issue with the provider itself. The terraform code of yours is an equivalent to running docker run ubuntu. This command also exits immediately since we did not provide any command to run. Please use the command attribute to specify a command to run.

Or you use must _run = false to get rid of the error message (but then you still won't have a running container, as it exits immediately without a proper command)
