Enabling "scaling to zero" functionality on faasd

[DanieleLattaioli]

My actions before raising this issue

• [ ] Followed the troubleshooting guide
• [ ] Read/searched the docs
• [ ] Searched past issues I've read this OpenFaas documentation https://docs.openfaas.com/architecture/autoscaling/ and under the section "Scaling up from zero replicas" it says that faasd can scale up from zero replicas. I've modified my function's yaml like this,

  version: 1.0
  provider:
  name: openfaas
  gateway: http://192.168.65.15:8080
  functions:
  hello:
  lang: python3
  handler: ./hello
  image: danielelattaioli/hello:latest
  annotations:
    com.openfaas.scale.min: "0"
    com.openfaas.scale.factor: "60"
    com.openfaas.scale.zero: "true"

Why do you need this?

I have some functions that are not triggered for a long time

Expected Behaviour

I would like to scale my functions replicas to zero

Current Behaviour

When I deploy the function with faas-cli deploy -f hello.yml and then faas-cli list, there is a replica of hello function

danielelattaioli@MBPdiDaniele2 Multipass % faas-cli list
Function                        Invocations     Replicas
hello                           1               1

Hi

Please refer https://github.com/openfaas/faasd/issues/353. Scale to zero is not supported in any community edition implementation of OpenFaas.

Thanks for the interest. The documentation you're referring to is about OpenFaaS on Kubernetes, the Community Edition of faasd doesn't support scaling to zero, however after a reboot, all functions start off at 0/0 replicas.
