ACI deployment - don't register every new container during spin up

Hello,

I've deployed SHIR as ACI.
Successfully tested reaching a private endpoint in our VNET.

I want to optimize the cost so I have created a pipeline where I will start cointainer before and stop after Data operation.
As the ACI will spin up a new container, Check-Is-Registered() will be always false and a new container will be registered to Data factory.

In the end several dead and one working container will be under Self Hosted Runtime item in ADF.

Is there any workaround or solution?

The only way I will try is to run "setup.ps1" as RUN command.
In this case I need to pass an AUTH_KEY via ARG in Dockerfile.

Thanks

R.V.
