title: Running custom linux images on Azure functions consumption plan
body: <p>Looks like Linux hosting for custom Functions containers are only supported on Dedicated (App Service) plans and Premium plans but not consumption plans. When I tried to do that I got errors about Linux workers not being available in the resource group.
  While I can get my custom image to run on the premium plan, it is turning out to be far too expensive. Is there a work-around to running it in the consumption plan? Is there a consumption plan exclusively with Linux workers?
  Also, what are cheaper alternatives for running a service (so far I have looked into Web Apps and Azure Container Instances) and I am looking for something cheaper. </p>
  
  <p>My service will be rarely called and will include un-trusted code (coming from client in the form of JS), so I am looking for something that is cheap, responsive and can be integrated with container registries (I am running a Node svc). </p>
