@icewizardry the container image you are targeting, xprobe/xinference:v0.14.0, has no entrypoint or cmd information, so the container can't start on its own without explicitly specifying what needs to execute inside of the container.

If you run docker inspect xprobe/xinference:v0.14.0 you will see that in the "Config" section "Cmd" is null and "Entrypoint" is null. It appears that the image was created with the ENTRYPOINT [] instruction, which reset the container startup information.

To deal with container images like that you need to specify the entrypoint and/or cmd info using the --entrypoint and --cmd flags.
