What is the right way to inform Nomad a job using the docker runner has a new image available and should be redeployed?
How about changing the docker tag in the job file and resubmit the job?
“psychic debugging” tells me that you could possibly mean that you are rebuilding the image with the same tag and want the Nomad agent to pull the newer image with the same tag.
This can be done with the force_pull option, but you will have to resubmit the job anyway (I think).
(That’s all what comes to mind for now 
)
Yes, the same tag and force_pull. Submitting the same job unchanged is all I need?
